Embodiments of the present disclosure relate to systems, devices, and methods for automation and energy management. More particularly, the present disclosure is directed to initializing and associating (e.g., by pairing, coupling, or linking) one or more energy consumption devices with appropriate control devices.
Conventional home automation systems have been available in the marketplace for many years. For example, the internationally-known X10 standard was one of the first standards commercialized for automating systems within a home, office, school, or other structure or dwelling. The X10 standard enables commands to be sent over the existing wiring in a structure, so that a controller can send messages to a controlled device. That is, one or more devices may communicate with one another over existing electrical wiring using the X10 standard. Controllers and controlled devices can be paired by manually setting the address or identifying information on the respective devices. Recent efforts to conserve energy have sparked additional interest in home automation. The existing and available solutions in the prior art, however, require large expenditures of capital and/or expert domain knowledge to facilitate installation. The current known prior art solutions are further limited by the fact that conventional outlets function in the same way regardless of the load (e.g., the particular electronic device) operably coupled to the outlet. In other words, a conventional outlet functions exactly the same regardless of whether a refrigerator, a clock radio, an incandescent, LED, or fluorescent light, a vacuum cleaner, a life support device, or another electronic device is plugged into the outlet. Such inflexible and non-discriminatory outlet set-up is not cost efficient, and does not optimize energy conservation.
There are solutions to differentiate the type of loads connected to an electrical network. For example, U.S. Pat. No. 8,094,034, entitled “Detecting Actuation of Electrical Devices Using Electrical Noise Over a Power Line,” discloses apparatus and methods for detecting electrical device actuation using electrical noise over a power line.
In addition, conventional power outlets do not readily allow differing controllers to regulate power delivery from the outlet. That is, conventional outlets are typically controlled by a single controller, such as, e.g., a switch, which may be disposed remotely of the outlet. Therefore, among other things, a more convenient method is needed to map or remap remote switches to remote outlets. In addition, an improved method and solution are needed to facilitate easy association of devices and their controllers that are part of a home automation system.
The previously mentioned disadvantages and limitations are overcome and other advantages are achieved with the embodiments described below.
In one embodiment, the present disclosure describes an automation system, including, but not limited to, a controller, remote switches, and remote outlets. The remote outlets may be configured to monitor power consumed by appliances plugged into the outlets, and the system may be configured to make a determination about the appliance. The determination may include identifying one or more characteristics of the appliance. In addition, the present disclosure describes, among other things, a method for selectively controlling an outlet or an appliance electrically coupled to the outlet by way of a pairing procedure. In one embodiment, when a pairing is performed, an appliance may be powered on or off to facilitate identifying control by a user interface, and allowing the user to select whether the subject appliance or another appliance is desired to be controlled by, e.g., a remote switch.
In another embodiment, a web application or an application on a mobile device may be capable of identifying candidate or otherwise controllable devices and remote switches, while enabling the user to select which devices should be paired with which remote switches. Embodiments of the disclosed method may also enable a remote switch to be paired with multiple outlets or candidate devices, so that a single switch can be easily paired to and control multiple devices.
Embodiments of the present disclosure are directed to systems, devices, and methods for intelligently controlling one or more energy consuming devices in a structure, including, but not limited to, a home, office, hospital, sporting complex, or school.

It may be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the present disclosure and together with the description, serve to explain the principles of the disclosure.
Reference now will be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts and/or components.
In one embodiment, a home automation system may include one or more switches and one or more outlets, with the user desiring which outlet or outlets are controlled by a particular switch or switches. Existing X10 devices require the user to manually set an address on the switch and the outlet, thereby encoding the outlet and switch so that they may communicate with one another. That is, an outlet would respond to a switch with an identical address, which would allow the switch to enable or disable power to the outlet on command of the identically addressed switch. This existing method may be limited to the available addresses which can be mechanically selected, and also requires physical access to the switch and the device (e.g., an outlet) being controlled. In addition, this existing method may create conflicts in situations in which one or more outlets and one or more switches share a particular encoding. Furthermore, some newly constructed buildings have the outlets in the ceiling to facility low cost remodeling and to enable the building to accommodate future equipment, such as, e.g., a projector. In such situations, it would be inconvenient to require a person to climb a ladder any time a ceiling mounted outlet or ceiling fixture was to be controlled by a remote switch.
Normal operation for a switch is for the user to turn the switch to an “ON” position to enable electrical energy to flow to the correspondingly controlled outlet (or device coupled to the outlet), and turn the switch to an “OFF” position to terminate the flow of electrical energy to the outlet (or device coupled to the outlet). In some cases, the switch may include an intermediate position, which meters an amount of voltage or current delivered to the outlet. In one embodiment of the present disclosure, turning the switch on and off several times in a short time, or executing some other user input pattern, may signal a desire to pair the switch with an outlet or device, which may be remote to the switch.
In accordance with one embodiment, a switch of the present disclosure may be in communication with all possible outlets that can be controlled. The outlets include a power monitor configured to determine if an appliance is connected to the outlet and if the appliance is drawing power from the outlet. The home automation system may be configured to create a list of outlets that are in communication with the switch and, e.g., have a device electrically coupled to the outlet. The list may include information relating to an identifying characteristic of the device(s) coupled to the outlet.
In one embodiment, when the user causes a switch to enter a pairing mode, as described in greater detail below, the automation system would create (or populate) a list of outlets that can be controlled by the switch and terminate delivery of electrical energy (i.e., power) to those outlets, pause power delivery for a predetermined time period such as, e.g., 2 seconds, and then re-enable power delivery to the outlets. In this manner, the user would see the controllable appliances that can be controlled turn off and then on, informing the user which devices are capable of being paired with the switch.
Further operations of the switch, e.g., would momentarily terminate power delivery to successive outlets in the previously compiled list. After the last device is selected by flipping the switch between the “ON” and “OFF” positions, the selection would proceed back to the beginning of the list. Thus, the user could, by means of flipping the switch between the “OFF” and “ON” positions, cycle through outlets (and devices coupled thereto) capable of being controlled by the switch.
Once the user has identified an outlet/device to be paired with the switch, the user may leave the switch in position for a pre-determined time period, such as, e.g., 5 seconds. The selected device would be powered off and then on to indicate it has been selected and the switch would exit pairing mode.
In some embodiments, however, it may be detrimental to interrupt power delivery to certain devices/outlets solely for the sake of pairing a control switch. In such embodiments, the switches and/or outlets may include indication means, capable of communicating information to a user. For example, rather than interrupting power as described above, a light source or speaker on an outlet/switch may be activated to indicate to a user whether a particular switch is in pairing mode, whether a particular outlet may be paired with a switch, and when a particular outlet is indeed paired with a switch.
This method enables the user to easily change which switch controls which outlet without adding extra switches or user interface components. In addition. the appliances themselves become part of the user interface in an intuitive user-friendly method.
Embodiments of the present disclosure can be further understood with references to
System 100 also includes other automation enhancements such as, e.g., a controller 160 (e.g., a mechanical controller) for, among other things, controlling the operation of, e.g., remote window coverings, doors, window panes, skylights, vent covers, fans, ducts, etc. Controller 160 may have any of the features of the controller described in U.S. application Ser. No. 13/672,534, entitled “SYSTEMS, DEVICES, AND METHODS FOR AUTOMATION AND ENERGY MANAGEMENT,” filed on Nov. 8, 2012, the entirety of which is incorporated herein by reference. Controller 160 may be configured to receive instructions from the control 110 via wired or wireless connection 119. The remote switch 120 may also communicate with controller 160 using wired or wireless means, although this connection is not shown in
A mobile device 170 may be wirelessly connected to the automation system 100 via wireless connection 175. The wireless connection 175 may be to the remote switch 120 as shown, it may also be to the remote outlet 130, controller 160, control 110, or any combination of these devices. The wireless transceiver in the mobile device 170 may include a method to measure received signal strength. The mobile device 170 may be connected through a Wi-Fi network and/or a cellular network (e.g., GSM or LTE).
With the transceiver 230, the switch 200 is able to send commands to a control device 110, such as the one described in
With continued reference to
In addition, switch 200 may include a mechanism for monitoring a state of switch 200. That is, the mechanism may be capable of determining whether the switch 200 is in a first (which may be an “ON”) position, a second (which may be an “OFF”) position, or an intermediate position. Further, switch 120 may be capable of monitoring the time between a transition from the “ON” position to the “OFF” position.
In one embodiment, the outlet 300 may include a microprocessor 310 that may be configured to run software stored in a memory 315. A wireless transceiver 320 connects the outlet 300 to a control device such as, but not including, the switch device 120 or control 110. The transceiver may operate on any suitable protocol, including, but not limited to, 802.11, zigbee, X10, or any other wired or wireless protocol known in the art. Line power from, e.g., a main power grid of a structure, enters the device at connection 350 to a power switch 330 controlled by the microprocessor 310. The power switch 330 may be operable to connect or disconnect the line power to the outlet 300 and any load(s) 360 connected thereto. Power switch 330 may be manually controlled and/or may be remotely controlled via, e.g., control 110 and/or mobile device 170. The power switch 330 also may be operable to reduce the voltage and/or current delivered to the load 360, thereby providing a dimming function. Power monitor 340 may be configured to measure the consumption of power by the load 360 coupled to outlet 300. The measured power data is sent to the microprocessor 310, and may be transmitted to another device/component in the automation system 100 using the wireless transceiver 320. The power monitor 340 may also measure noise on the line to the outlet 300, as described in U.S. application Ser. No. 13/672,534, entitled “SYSTEMS, DEVICES, AND METHODS FOR AUTOMATION AND ENERGY MANAGEMENT,” filed on Nov. 8, 2012, the entirety of which is incorporated herein by reference. Outlet 300 may include an interface to load 360 (e.g., a receptacle) that can be any connection to provide power to a device including standard 2 or 3 pin power outlets, 220V outlets, international standard outlets, and may also include wireless transfer of power such as a wireless charger.
Monitoring and analyzing the noise on the power supply can be used to determine the type of load present, as discussed and taught in detail in U.S. Pat. No. 8,094,034. According to one embodiment of the present disclosure, the apparatus and method disclosed herein may be used to further monitor an entire structure to determine what loads are turned on or off and corresponding user activity is then inferred.
By monitoring the power consumption characteristics of the load coupled to the outlet 300, characteristics of the device may be determined, using the techniques taught in U.S. Pat. No. 8,094,034. In addition to the methods thought in the '034 patent, any suitable means for identify one or more characteristics of a load may be used. Based on the characteristics, the load (e.g., an electrical device coupled to the outlet) can be beneficially and intelligently controlled, for example an outlet supplying power to a television may disable power to reduce the power drawn by the device, but an outlet providing power to a clock radio or a refrigerator would remain energized, and thus to enhance the users environment, reduce energy consumption, and ease setup of automation systems.
At step 410, a monitoring mechanism in the switch 120 may monitor the state of the switch and identify whether the switch is an “ON” position, an “OFF” position, or an intermediate position. The monitoring mechanism may also be configured to monitor whether the state of the switch has been changed multiple times within a predetermined period of time or otherwise put in a pairing mode. If the switch is activated multiple times such as, e.g., on/off/on/off within a predetermined time period such as, e.g., 3 seconds, then the switch may enter a pairing mode and execution proceeds to step 420. If the switch is not activated multiple times in a predetermined time period such as 3 seconds, the switch remains in normal operation mode. That is, the switch continues to control power delivery to whatever outlet or load it is already controlling. In one embodiment, the monitoring mechanism may be configured to detect a position of the switch 120. In another embodiment, the monitoring mechanism may be configured to determine whether energy is flowing through the switch 120.
At step 420, the automation system 100 creates a list of all the outlets 130 that the particular switch 120 can communicate with. The list can be determined by the switch 120 sending a signal, e.g., a wireless signal, using, e.g., WiFi Transceiver 230 or transceiver 235, the signal causing outlets or devices that receive the signal to respond with the identity of any loads coupled thereto. As alluded to above, the identity of particular loads may be determined e.g., by comparing power consumption and electrical noise generated by a particular load. In some embodiments, the list may be preprogrammed into a memory of the automation system 100, or the list may be determined using other means as is known in the art. It is envisioned that a single outlet with, e.g., two plug receptacles may be treated as two items for this list, thus enabling two devices plugged into a single outlet to be individually or collectively controlled. That is, each plug receptacle of an outlet 300 may be configured to independently communicate with a switch 120 in response to a signal emitted by the switch 120.
At step 430, the list of outlets or devices may be reduced. For example, outlets without connected appliances or other electrical devices that are not drawing power may be removed from the list. Remote outlets such as outlet 130 may include a power monitor 340 that enables the outlet to determine if an appliance is connected and drawing power. Thus, an outlet may determine if an appliance/electrical device is plugged in and turned on, and the information may be communicated by the outlet 130 to control 110, switch 120, or any component of automation system 100. Outlets or devices without loads may be removed from the list. It is envisioned that step 420 and 430 may be combined in some embodiments. The remote switch 120 may send a message using WiFi transceiver 230 or transceiver 235 requesting outlets respond if a power consuming device is coupled thereto. The outlet 130 would determine if an appliance is attached and drawing power, and respond with the identity of devices connected thereto. An outlet with multiple receptacles may respond with a single identity if a single device is plugged in and drawing power, may respond with multiple identities if the outlet has multiple receptacles and more than one receptacle has an appliance plugged in and drawing power, or may not respond if the outlet does not detect a connected appliance drawing power or if the connected appliance is not drawing power exceeding a threshold. By responding, it is envisioned that the outlet will be configured to receive a signal, e.g., an electrical or radiofrequency signal, emitted by a switch, and then in turn emit a response signal which will be received by the switch. The response signal may include information pertaining to one or more characteristics of a load coupled to the outlet 130. In an alternate embodiment, the outlet may respond with and indication that no load is present.
At step 440, a list is generated, the list including the outlets and corresponding devices that can be controlled by the switch 120, and have appliances attached. In some embodiments, the list may be further reduced by eliminating those outlets coupled to a load that is in an inoperative, not present, or operating in a reduced power consumption state. In addition, the list may be arranged in any suitable order. For example, the list of outlets may be ordered by decreasing signal strength. This would roughly order the outlets and corresponding devices that can be controlled by the switch, in a sequence of those closest near the top of the list with the highest signal strength, to those farthest at the bottom of the list with the lowest signal strength.
At step 440, the list may also be reduced by any devices or appliances that are essential and cannot or should not experience an interruption in power supply. As alluded to above, outlets 130 may include a include power monitor 340 that can detect if the connected appliance is drawing power as well as characteristics of the power drawn such as, e.g., quantity, time characteristics, noise characteristics, etc. By monitoring these characteristics and comparing them to a database of devices and their power characteristics, the type or category of electrical device/appliance may be identified. If the device is determined to be a refrigerator, clock radio, a ventilator, or another device that may be identified as not switchable or incapable of experiencing an interruption in power delivery, then the device may be removed from the list, even though the device is connected and drawing power. The database may be stored in the automation system 100 or may be remotely accessible via the cloud 140. The comparison may be performed in or by the control 100, the outlet 130, the switch 120, or in a remote server accessible through cloud 140.
It is envisioned that steps 420, 430, and 440 may be combined or be performed in any suitable order, with one or more portions of any of these steps being omitted. A single message signal may be sent from the switch 120 to outlets 130 and devices coupled thereto and/or controller 160, where the devices and outlets respond with information relating to an identity of a device coupled to the outlet 130 or controller 160 if the outlet is connected to an appliance, the appliance is drawing power in excess of a threshold, and/or the appliance is not identified by the power consumption characteristic as an essential appliance for which power supply should not be interrupted.
During step 450, all outlets 130 and devices coupled thereto that remain in the list may be turned off, a time period is waited such as, e.g., 2 seconds, and the devices and outlets are turned back on. In other words, delivery of electrical energy to all outlets and corresponding devices is interrupted for a predetermined period of time. This would allow the user to see the devices turn off and on, thereby providing indication of which devices are available for pairing with the switch that has been put into pairing mode. As discussed herein, the outlets 130 may include other means (e.g., an LED light or a speaker) for providing an indication to a user which outlets are available for pairing with a particular switch.
At step 460, if the user does not activate the switch 120 within a predetermined time period, such as, e.g., 5 seconds, execution of the method may proceed to step 486. If the user does activate the switch 120, however, where the activation may include turning the switch on and then turning the switch off at step 460, then execution may proceed to step 470, where power delivery to the first member of the set of outlets and coupled devices is interrupted for a predetermined time period, such as, e.g., 2 seconds, and then the power is turned back on. This will indicate to the user that the first device will be paired with the switch 120 if the switch 120 is not activated again while in pairing mode.
Following pairing with a particular outlet 130 or device coupled to an outlet 130, the switch 120 may transmit a signal (e.g., a wireless signal) to all outlets 130 informing those devices and outlets to cancel any pairing with the switch that is in pairing mode. Since the user has put the switch into pairing mode, and selected a possible device for pairing, control of any previously paired device should be also disabled. This may be accomplished by the switch 120 sending/emitting a signal carrying the switch's identification and a request to cancel prior pairings. All devices and outlets receiving the message would compare the identity of the switch 120 to information stored in the device or outlet memory. If the identification of the switch sending the signal matches information stored in the device or outlet memory, such as memory 315, then the device or outlet may modify information stored in the memory so that the device or outlet will no longer respond to the switch in pairing mode. This facilitates remapping switches to new devices or outlets.
At step 470, the user may activate the switch 120 again before a time period expires such as, e.g., 5 seconds. If the user does activate the switch 120 before the time period expires, execution of the method may proceed to step 485 where the next member of the set of outlets and devices is turned off, and then turned back on after a short time period, execution then passes back to step 480. If the end of the list is encountered at step 485, the next member selected may be the first member of the set.
If the user does not activate switch 120 during step 480 before the time period expires, then execution proceeds to step 486. At step 486, if the user has not activated the switch 120 at least once after pairing mode was entered, then the user may have entered pairing by mistake, no change is made to the pairing of the switch 120, and the switch 120 exits pairing mode at step 488. The switch 120 may be configured to wait another predetermined period of time (e.g., 10 seconds) to determine if it will be activated when in pairing mode before pairing mode is exited.
At step 486, if the switch has been activated at least once within the predetermined time period after entering pairing mode, then execution proceeds to step 487. During step 487, the last member of the set of outlets for which power was interrupted is paired with the switch. Subsequently, power delivery to the paired outlet/device is interrupted twice for a brief pre-determined period of time, such as, e.g., 2 seconds. Doing so will provide an indication to the user that the selected outlet/device has been paired with the switch 120. In addition, outlets 130 and switches 120 may include an integrated light source, such as, e.g., an LED. Thus, rather than interrupting power delivery to the outlet and any coupled devices, the LED on particular outlets may flash to indicate when, e.g., they are selected for pairing and/or paired with a particular switch. In this manner, it is contemplated that interruption of power delivery may be avoided during a pairing exercise, so as to avoid electrical malfunction of devices/appliances.
If the user does not activate the switch 120 within a time period such as, e.g., 5 seconds after the switch 120 enters pairing mode, then execution proceeds to step 488 and the switch 120 exits pairing mode. If the switch 120 is on, any paired device is turning on, if the switch 120 is off, the paired device is turned off. Alternately, the switch 120 may request that the outlet 130 toggle operation when the switch 120 is activated, for example, if the outlet is on and the switch is activated, the outlet may toggle off, or, alternatively, if the outlet is off and the switch is activated, the outlet may toggle on. That is, if the device or outlet is on, and the switch 120 is activated, then the device or outlet 130 may be turned off, and if the device or outlet 130 is turned off when the switch is activated, then the device or outlet maybe turned on, regardless of the switch position relative to its “ON”/“OFF” positions prior to pairing.
In some embodiments, after a switch is paired, entry into pairing mode for that particular switch may be disabled so that multiple operations within a predetermined time period may no longer enable the pairing mode. In addition, a user may be capable of manually disabling pairing mode by adjusting a safety control on a switch 120. This may be advantageous to prevent inadvertent activations from, e.g., children causing a switch 120 to enter pairing mode and affecting current pairings. If the remote switch loses pairing information, or the remote outlet no longer responds to the remote switch, then the pairing mode may again be permitted. A light source may be activated on a switch experiencing pairing difficulties such as, e.g., loss of pairing information. It is expected that the switch may send a message when the user changes the state of the switch. A paired device would react to the message and may send a response to the switch acknowledging that the message was received. If a message is not acknowledged, the switch may declare that the pairing is no longer valid, and re-enable pairing mode. Then, future multiple activations would enable pairing mode in the switch.
In some embodiments, it is envisioned that a device capable of being paired with a switch 120 may be controller 160, e.g., which can close, open or otherwise control, e.g., a window treatment such as a shade, blinds, drapes, LCD film, or any other window covering or treatment. In addition, any suitable enhancements, such as, e.g., irrigation control, that can be controlled by controller 160 may be paired with a switch of the present disclosure. Method 400 is expected to apply to allow these enhancements to also be paired with remote switches. For example, a remote switch turned on may be equivalent to opening a window treatment, and a remote switch turned off may be equivalent to closing the window treatment. A remote switch that allows continuous input, such as a dimmer switch, may be paired to a window treatment control and may continuously adjust the state of the window treatment instead of strictly opening or closing the treatment. In addition, continuous input remote switches may also control intermediate states of operation.
The execution of method 400 may occur in the microprocessors located in the control 110, the switch 120, the outlet 130, controller 160, a server accessible via the internet cloud 140, or a combination of these.
Method 400 allows the user to step through the available outlets and corresponding devices for pairing by manually operating the switch to advance through a list of available outlets and corresponding devices. Alternately, once the switch is in pairing mode, the switch may automatically advance through the list, cycling power at each available outlet or device, with a time period pause between devices. Power delivery to the device or outlet would be briefly interrupted in a predetermined pattern such as on/off/on to indicate which outlet/device is presently selected. The user could manually operate the switch to indicate which outlet/device is to be paired. The switch may sequentially cycle through the list of possible outlets and devices one, two, or more cycles to provide the user multiple opportunities to select a desired outlet/device. If the user does not select an outlet or device within a predetermined time period, or a predetermined number of cycles, the switch would exit pairing mode after cycling through the list one or more times. If the user does indicate a selection for pairing by operating the switch when the desired outlet or device is selected, then the switch may send out a message to all devices to unpair (i.e., effectively clearing any previous pairings) the switch as a control device and then send a message to the user-specified device that it should pair with the switch.
At step 520, the mobile device 175 may communicate with remote switches (e.g., switches 120), remote outlets (e.g., switches 130), and other devices within range of the mobile device or within a particular structure. The mobile device 175 may send a signal asking for remote switches to respond, the switches may reply with their identity and the state of the switch. In other words, the mobile device 175, via, e.g., the Internet or cloud 140, may send a signal to all switches that are part of a structure. All switches receiving the signal may then respond with another signal including information relating to, e.g., the switch's location and whether the switch is in an “ON” position, an “OFF” position, or an intermediate position. The mobile device 175 may collect and tabulate the responses it receives. In addition, the mobile device may include software configured to create a list of the remote switches that respond. Furthermore, the list of remote switches may be arranged in any suitable order. For example, in one embodiment, the list of remote switches may be ordered by decreasing received signal strength, which may correspond to distance away from the mobile device. In addition, remote switches may be arranged or grouped by their location within a structure such as, e.g., by floor or room. In embodiments where response signal strength is used, the switches may be configured to receive and emit a wireless signal (via e.g., Bluetooth or radiofrequency). Accordingly, the mobile device 175 also may be configured to receive and emit a wireless signal. This will result in a list where the closest switch is near the top of the list, switches further from the mobile device would be further down the list. The list may include the switches and the state of each switch (e.g., whether the switch is in an “ON” position, an “OFF” position, or any suitable intermediate position). In addition, the mobile device 175 may be configured to display any pre-existing pairing relationships any of the switches may already have.
At step 530, the user adjusts a position or state of the switch (by, e.g., flipping the switch) that the user desires to pair to an outlet/device. The subject switch may then send out a message via a wireless signal that the switch state has changed, the mobile device or another control panel may receive the message, and consequently update the user interface (e.g., in real-time) to show the switch changing state. The user may then select one of the listed switches to be paired on the user interface of the mobile device. Multiple switches also may be selected. The user may then select one or more outlets/devices to be paired with the selected outlets/devices, as discussed in greater detail below.
At step 540, the mobile device communicates with remote outlets 130 and devices that can be controlled such as a controller 160 for, e.g., a window treatment. The mobile device would send out a request via a wireless signal to outlets and devices. The outlets and device may respond with a wireless signal including information relating to one or more characteristics of the outlets and/or devices coupled thereto. The outlets and devices may include information on the appliance/device electrically coupled to the outlet. If the automation system 100 has determined or received information relating to identity characteristics of any of the appliances coupled to controlled outlets, this information may be communicated to the mobile device and displayed on the mobile device user interface. For example, if it is determined that a television is coupled to a controlled outlet, a graphic (including, e.g., symbols, letters, and/or images) may be displayed adjacent the outlet 130 to which the television is coupled. With reference to
At step 550, using mobile device user interface, the user may select one or more outlets or devices coupled thereto. The user may indicate that an outlet/device should be turned off by, e.g., touching the user interface, the mobile device sends a message (e.g., via a wireless signal) to the indicated outlet/device, and power delivery to the outlet/device may be terminated and/or reduced, which would turn off any device connected thereto. Thus, the user can confirm that the selected outlet on the user interface is actually correlated with the device the user wishes to control with a remote switch. Any suitable representation other than line 1060 may be used, however.
At step 560, using the mobile device user interface, the user selects to pair one or more selected switches with one or more outlets and/or corresponding devices. Subsequently, the mobile device may send a message via a wireless signal to the automation system 100 to pair the selected outlet(s)/device(s) with the desired switch(es). As alluded to above, more than one switch and outlet may be selected and paired.
By manipulating the user interface, the user may access each outlet or receptacle and selectively turn each outlet or receptacle on or off, independently or collectively. The user may also access information from each of the home automation devices such as model number, software version, hardware version, data from the power monitor of any device, data from sensors located in any device, and/or any identifying characteristics of a load connected to one or both receptacles of the outlet.
In one embodiment, the user interface may be configured to allow a user to intelligently control the power delivery to one or more outlets and/or devices coupled thereto. That is, the automation system and/or user interface may be configured to execute pairing or unpairing of switches and outlets based on pre-programmed instructions. For example, the user interface may allow automatic pairing or de-pairing at certain times of the day, certain days of the week, or certain months of the year. In addition, the user interface may allow preferred pairing based on an identity of certain devices. That is, the user interface may be programmed to always pair a single switch with any outlet to which a particular device/appliance is connected.
It is proposed that an outlet or device with multiple outputs or receptacles may have some of the outputs activated and some deactivated. For example, in
Some devices plugged into the outlets may be identified as a protected class. Devices in the protected class may be appliances identified as a device not to be disabled, such as a refrigerator or a clock radio, security system component, medical device, or any other device or appliance that may be determined to be detrimental to disable the power to the device. The device or appliance may be identified by a characteristic of the power drawn by the device, it may be identified by a characteristic of the noise the device generates in a power line, it may be identified by a sensor attached to the automation system such as a camera, the device may communicate to the home automation system over a wired or wireless connection and identify itself, or the user may identify the device by manipulating a user interface to enter data about the device into the automation system. When a protected class device is known to be connected to the automation system, it may be displayed on a user interface to indicate that the outlet or receptacle providing power to the device should not be disabled. The user interface may further indicate that a receptacle or outlet powering a protected class device is not a valid selection for pairing. Should the user manipulate the user interface on the controller or mobile device to turn off an outlet or receptacle powering a protected device, the user interface may indicate that executing the chosen action would disable a protected device. A password may be required prior to executing the action of disabling a protected class device or appliance.
In another embodiment, switch 120 may be removably attached to a wall. When removed from the wall, prongs for a wall plug extending from switch 120 may be moved from a stored position to an extended position allowing the switch 120 to be plugged into an outlet 130. When the switch is plugged into an outlet the switch may recharge a battery associated with the switch. When the switch is plugged into an outlet, the switch may associate with the outlet so that after unplugging the switch from the outlet, operation of the switch user interface will control (e.g., wirelessly) the outlet the switch was plugged into. Moving the plug of the switch into an extended mode may cause the switch to enter into a pairing mode, a charging mode for a battery, or both a pairing and a charge mode. Moving the plug of the switch into a stored position may cause the switch to resume a normal operating mode, where operation of the switch controls a paired device or outlet.
The switch may include a user input device such as a button, slide, touch screen, etc., which may enable the switch to pair with an outlet when plugged in. The switch could be plugged into a first outlet, and the user interface of the switch may be manipulated by the user enabling the switch to pair with the outlet. The switch may then be plugged into a second outlet, for example an outlet located above a kitchen counter. The switch would draw power from the second outlet, and operating the switch may control the first outlet that is paired with the switch.
