Embodiments of the present disclosure are directed to systems, devices, and methods for automation and energy management. More particularly, the present disclosure is directed to sensing and controlling the energy consumption of electrical devices based on one or more characteristics of the 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, or school. 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 electrical 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 light, a vacuum cleaner, a life support device, or another electrical 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 in the prior art 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.

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.
a and 6b depict flowcharts of exemplary methods for maintaining a constant level of light with an embodiment of an automation system disclosed herein, in accordance with the present 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.
Embodiments of the present disclosure including, among other things, an automation system with a controller, remote switches, and remote outlets. The remote outlets may be configured to monitor power consumed by one or more electrical devices, such as, e.g., appliances, plugged into or otherwise coupled (e.g., wirelessly) to the outlets. In addition, the system may be configured to make a determination about the one or more electrical devices. The determination may include identifying a category or type of device for the one or more electrical devices. Based on the determination, the system may modify how power is supplied, if at all, to various electrical devices coupled to the system.
In another embodiment, the disclosed automation system may be configured to automatically determine whether a device requires a constant supply of electrical energy or whether energy supply may be temporarily terminated or otherwise reduced to lower energy costs. For example, the disclosed automation system may identify critical devices, such as, e.g., a clock radio, refrigerator, and/or medical devices, and ensure such devices receive continuous electrical energy. On the other hand, the automation system may identify non-critical devices, such as, e.g., a television and/or stereo, and terminate energy delivery after, e.g., an extended period of inactivity. Such functionality may also be associated with potentially dangerous home devices, such as, e.g., an iron. It is contemplated that the disclosed automation systems are capable of making such identifications without user intervention.
In a further embodiment, the automation system may be configured to determine the presence of a device, such as a fan, and based on the presence reduce the energy consumption of a second device, such as, e.g., an air conditioning, heating, or humidifying device. This modification would occur without any user intervention.
It some embodiments, the characteristic of a load or electrical device coupled to the home automation system may be determined by monitoring and analyzing the noise in power supply lines. One exemplary method of such monitoring and analyzing is discussed in U.S. Pat. No. 8,094,034 entitled “Detecting Actuation of Electrical Devices Using Electrical Noise Over a Power line”.
According to a further embodiment of the present disclosure, the disclosed systems, apparatus, and methods may be used to monitor an entire structure, such as, e.g., a home, office, school, hospital, or sporting complex, to determine what loads are turned on or off and the user activity may be then inferred. In another embodiment, the disclosed systems, apparatus, and methods may be configured to monitor a plurality of independent structures to determine what loads are active, infer usage activity from the determination, and control usage in a manner to optimize efficiency and/or energy consumption.
By monitoring a device's power consumption characteristics at the outlet, various features or use parameters of the device may be determined, In other words, the outlet, and the automation systems disclosed herein, may be able to “learn” an identity or category of the device and/or usage characteristics. Based on the identified features/parameters/characteristics, the device 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 television after a predetermined time and/or upon detection of an unoccupied viewing area. On the other hand, however, an outlet providing power to a clock radio would remain energized, regardless of time or occupancy in the immediate area. That is, if an outlet of the present disclosure determines that the load (i.e., the electrical device drawing power from the outlet) is a clock radio, the outlet may ignore commands to disable power, thereby allowing the clock radio to continue its normal function of waking an individual sleeping nearby.
In another example, if the load is determined to be an incandescent lamp, the outlet may allow dimming to provide ambiance or conserve energy. However, if the load is determined to be fluorescent, dimming would be restricted, since the ballasts typical of such lights malfunction at reduced voltages.
In a further example, a portable battery charger, such as, e.g., the charger of a laptop or cellular phone battery, may be coupled to an outlet according to the present disclosure. In this example, the outlet could monitor the outlet power transfer characteristics to identify that the load is a battery charger. The disclosed automation systems could then ensure the charger remains energized so as to allow complete charging of the battery. Once the battery is charged, the charger may switch to maintenance mode and would therefore reduce the amount of power it draws from the outlet. Once the charger's reduction in energy consumption is detected by the outlet, the automation system of the present disclosure may terminate energy to the outlet, thereby conserving the energy that would have been consumed by the charger when in maintenance mode.
Accordingly, the principles of the present disclosure serve to enhance a user's environment and reduce energy consumption through the use of an easy-to-setup automation system.
The embodiments of the present disclosure can be further understood with references to

For example, upon sensing moisture or gas in the vicinity of outlet 130, switch 120 may interrupt power supply to outlet 130. Like outlet 130, switch 120 may also include one or more sensors for sensing, among other things, temperature, motion, air quality, pollutants, contaminants, light, sound, humidity, liquid, air flow, and/or certain signals, such as, e.g., radio frequencies (RF) or infrared. The inputs from such sensors may also cause switch 120 to temporarily interrupt, change, adjust, and/or meter the supply of power to outlet 130.

In some embodiments, control 110 may reside in the Internet cloud, and the functions of control 110 (or any of the microprocessors disclosed herein) maybe executed on any suitable server located in the Internet cloud or storing data/algorithms relating to control 110. If control 110 is located in the Internet cloud, connections 115, 116, and 119 may include connections to the Internet cloud to the control 110. For example, outputs from sensors 240/340 may be communicated to the Internet cloud.

In some embodiments, switch 200 may also include a second wireless transceiver 235 for allowing switch 200 to communicate with one or more devices (e.g., outlet 130 or any electrical load coupled to outlet 130) being controlled by switch 200. As those of ordinary skill in the art will recognize, first and second wireless transceivers 230, 235 may allow for communication over one or more communication protocols. In addition, first wireless transceiver 230 may be configured to communicate over a protocol that is different from the communication protocol of second wireless transceiver 235. Moreover, in some embodiments, switch 200 may only include a single transceiver for communication with both control 110 and multiple controlled devices. In such embodiments, the single transceiver may be also replaced by a suitable single wired communication mode. Even further, switch 200 may include a transceiver for each device it controls. Furthermore, second wireless transceiver 235 may be configured to send/receive messages to/from a user's portable communication device and/or local emergency authorities, For example, in the event of a system malfunction, system 100 may notify a user by sending, e.g., a text message to a user's cell phone or e-mail account. In addition, if one or more sensors detect, e.g., the presence of gas or temperatures associated with fire, the system 100 may automatically alert local emergency officials.

Electrical power received at connection 350 may first pass to a power switch 330, which may be controlled by microprocessor 310. Power switch 330 may be also manually controlled by a user. Further, power switch 330 may be remotely controlled by a user via, e.g., web-enabled application and/or a mobile platform. The power switch 330 is operable to connect or disconnect the line power to/from the outlet 300 and any connected load 360 (e.g., any electrical device coupled to outlet 300). In some embodiments, power switch 330 may be configured to control (e.g., interrupt, change, adjust, terminate and/or meter) the quantity of electrical energy delivered to outlet 330.

In some embodiments, microprocessor 310 may be coupled to power monitor 341 by any suitable connection. The power monitor 341 may also measure noise in the connection to load 360. Connection 360 can be any connection known in the art for providing power to electrical devices. Such connections may include standard 2 or 3 pin power outlets, 110V/220V outlets, international standard outlets, and may also include wireless transfer of power by, e.g., means of induction. The connection may also allow direct wired connection to a load such, for example, a ceiling fan, a flood lamp, light fixtures, or other devices which maybe directly connected to the power grid in a building.
Outlet 300 may be also operably coupled to one or more sensors 340. Sensors 340 may be configured to sense, among other things, light, motion, sound, temperature, humidity, air quality, pollutants, contaminants, water quality, air flow, and/or certain signals, such as, e.g., radio frequencies (RF) or infrared.

In one embodiment, it is contemplated that automation system 100 may terminate power delivery to an outlet 300 if outlet 300 or an associated switch detects a nearby RF or infrared source. Particularly, it is contemplated that an infrared or RF generating device may be worn by, e.g., a toddler or a pet. If the toddler or pet approaches to within, e.g., 1-3 feet of a particular outlet 300, the outlet 300 and/or switch 200 may detect the infrared/RF source, and automation system 100 may temporarily terminate power delivery to that outlet 300. Doing so, may prevent accidental electrocutions should the toddler or pet insert a metal object (e.g., a fork) into the outlet 300.
Like switch 200, outlet 300 may be a standalone device configured to be installed in, e.g., a home, and work seamlessly with pre-existing wiring. In some embodiments, outlet 300 may be an adaptor configured to be plugged into pre-existing electrical outlets. In such embodiments, the adapter may include a plurality of electrical pins for coupling with an existing electrical outlet. The adaptor may also include a plurality of ports to receive the electrical pins of an electrical device. The adaptor may have all of the components and features of outlet 300 discussed above. In one embodiment, the adaptor may be configured to plug into existing electrical outlets. In this embodiment, for example, the line power 350 is provided to the adaptor from the existing electrical outlet. The adaptor may also have the form of an extension cable, where the adaptor includes at one end of a power cord having a plug configured for connection to an existing electrical outlet, and may include a receptacle at a second end to accept a plug from an electrical device, where the components of outlet 300 may be included in the cable, or one of the ends of the cable. It is also envisioned that the adaptor may be in the form of a power strip that includes one or more electric receptacles, with a power cord to attach to an existing receptacle. The adaptor advantageously enables building automation to be added to existing structures without re-wiring existing electrical service.

At step 401, for example, power monitor 341 of outlet 300 may monitor the power consumed by the various loads 360 plugged into a plurality of outlets 300. The power monitor 341 may also analyze the noise generated by each of the loads to identify each load and/or group/characterize loads by category. The monitored data may be communicated to microprocessor 310. The automation system 100 may also monitor the usage of one or more loads, step 402. More particularly, in addition to monitoring the power consumption of a load, automation system 100 may monitor the use characteristics of one or more loads 360. For example, automation system 100 may track and store historical data of, e.g., when certain loads are typically used, the duration of each use, and the like. For example, automation system 100 may identify that a particular load connected to one outlet 300 is a washing machine. Automation system 100 may also monitor and store the usage trends of the washing machine, which may be, e.g., 2 hours once a week on Sunday. Further, at step 403, e.g., automation system 100 may monitor various conditions nearby one or more outlets 300 by monitoring the inputs of one or more sensors 340.
The monitored data may be captured and sent to the microprocessor 310.
The data may be analyzed by microprocessor 310, or sent via transceiver 320 to switch 200 and processed in microprocessor 210 or sent to another computing device connected to switch 200 or outlet 300. As alluded to above, the data may be analyzed to determine the nature of the load. For example, the characteristics of the load, such as, e.g., power consumption and/or noise generated in the power lines, may be compared to a database(s) of known loads or load categories. Based on the comparison, the load connected to outlet 300 may be identified and/or categorized. The database may be a compilation of previously identified load characteristics. In addition, the database may be updated continuously by any known methods. For example, the principles of crowdsourcing may be employed to ensure the database(s) is kept up-to-date. More particularly, the database may be configured to receive and store monitored characteristics from a plurality of automation systems. In this manner, the database may be continuously updated as new electrical devices enter into the market and are put to use.
As the monitored data is analyzed and various loads are identified, a determination is made if the device can tolerate dimming or reduced voltage. For example, automation system 100 may adjust or terminate power delivery to non-critical devices, step 404. More particularly, if automation system 100 identifies a load as a non-critical load, automation system 100 may terminate power delivery. For critical devices, however, power delivery may continue uninterrupted. Examples of critical devices include, but are not limited to, refrigerators, clock radios, ventilators, life-support machines, electronic safes, heating/cooling systems. On the other hand, certain identified loads may be suited for reduced voltage. For example, incandescent lights may tolerate or benefit from a reduction in voltage (e.g., dimming). Thus, if automation system 100 identifies a particular load suited for dimming, the automation system 100 may reduce the voltage provided to that load after, e.g., a predetermined lapse of time or a lack of motion in the vicinity of the load. For incandescent light bulbs, for example, a light sensor may detect an increase in ambient light (e.g., sunrise), and automation systems 100 may consequently reduce the voltage to the bulb, thereby saving power. If a detected load is unable to tolerate a reduction in voltage, automation system 100 may continue power delivery. Alternatively, automation system 100 may terminate power delivery after, e.g., a predetermined time lapse.
In one embodiment, e.g., automation system 100 may ensure critical devices continue to receive the power needed for them to function in the event of a power failure. For example, an embodiment of automation system 100 may include a back-up generator. In such an embodiment, automation system 100 may automatically route power generated by the back-up generator to those outlets 300 supporting critical devices.
As noted above, automation system 100 may be configured to monitor one or more sensors, e.g., sensors 240/340. Thus, if a sensor 240/340, e.g., a motion sensor, senses that a person enters a room in the vicinity of a particular load, or by a load change indicative of user intervention (for example, an increase in power consumption by a refrigerator attributed to the courtesy light may be an indication that someone is in the kitchen), the automation system 100 may re-enable power delivery to one or more outlets 300, step 405. In another example, a doorway to a room (e.g., a kitchen) may have a threshold motion sensor. Thus, when a user crosses the doorway, the automation system 100 may re-enable power delivery to all outlets 300 in the room. In this manner, outlets 300 and loads 360 that were disabled to conserve power in the absence of activity may be reactivated when a user is present or nearby. This step allows a person to turn on, e.g., the coffee maker in a kitchen or a hair dryer in the bathroom without taking additional steps to enable the outlet to which these devices may be connected. This simplification will greatly improve the usability of automation system 100 and insure that users take advantage of the ability of automation system 100 to conserve resources and reduce energy costs. Further, embodiments of the present disclosure provide for remote operation of automation system 100, switch 120, and/or outlets 130. For example, power delivery to a particular outlet 130 may be terminated remotely by a user via, e.g., a web-enabled application or a mobile platform to selectively conserve power. Similarly, automation system 100 may allow a user to selectively re-enable power delivery remotely. For example, the user may be able to turn on one or more lights when a home is unoccupied.
Continuing with the exemplary method of
As noted above, once automation system 100 determines the types of loads coupled to outlets 300, automation system 100 may be able to identify those devices which require continuous power delivery and refrain from terminating power to those loads. Loads that may be exempt from having their outlets disabled may include, but are not limited to, clocks, refrigerators, heating/cooling systems, security and safety systems (e.g., smoke detectors), ventilators, healthcare devices, and/or computing networks.
The steps of method 400 may be executed on microprocessor 210, microprocessor 310, another microprocessor connected to the outlet 300 or connected to the switch 200, or by a combination of these microprocessors.
One benefit of method 400 is to enable enhanced services such as dimming when the device plugged into the outlet is capable of supporting dimming, without additional user intervention. For example, if a vacuum cleaner is plugged into outlet 300 controlled by switch 200, the switch 200 will function as an on/off switch, preventing possible damage to the appliance caused by providing inadequate power. If, however, a lamp is plugged into outlet 300 controlled by switch 200, the switch 200 may dim the lamp (provided the lamp supports dimming) without additional user input.
Control 110 may allow the user or a system administrator to set a control to determine how aggressively devices may be controlled or disabled. By making a selection, the user may cause the control 110 not to disable devices at all, to select which devices will be disabled, and/or to determine how long to wait before disabling devices. In one example, a coffee maker may include a timer to automatically start brewing. A user may utilize the timer function to automatically begin brewing coffee at, e.g., 6 AM in the mornings. Thus, the user may want the outlet to which the coffee maker is plugged into to stay energized to allow coffee to be prepared as per the timer. Thus, the automation system 100 of the present disclosure may allow cost conscience users to selectively designate those devices which may receive continuous power delivery (even if the device is a non-critical load) while terminating power delivery to other devices. In addition, the automation system 100 may allow a user to designate the time delay before certain devices are enabled.

If, based on the principles of load identification disclosed herein, automation system 100 identifies a television or other monitor operating within a certain area (step 502), the automation system 100 may control one or more window coverings to control a level of light in the room (step 503). More particularly, if it is determined that a television or other display is operating, and the sun is shining, and the sunlight is shining on or in the vicinity of the television, then the control 110 would order the controller 160 to close the window coverings to a position such that the sunlight is blocked from directly shining on the appliance. The determinations of sunlight levels and direction may be made by one or more light sensors operably coupled to automation system 100 and/or the television/monitor.
Similarly, if automation system 100 determines that a room is empty, control 110 may command controller 160 to close window coverings to, among other things, reduce the load on a heating and air conditioning system, thereby conserving energy and reducing costs. The room may be determined to be empty from sensor (e.g., motion sensor) data. In addition, a room may be identified as empty from power consumption data collected from, e.g., outlets in the room. For example, if power consumption at a majority of outlets in the room is at a minimum (e.g., TV is off, lights are off, etc.), automation system 100 may understand that there are no users in the room.
In some embodiments, a user may choose to place, e.g., plants or pets in a room. In an embodiment where the user places plants in a room, e.g., the presence of plants may be programmed into automation system 100, or may be discovered from sensors 240, which may include cameras, CO2 sensors, O2 sensors, and humidity sensors. In addition, once a user informs automation system 100 of plants, or plants are detected, in a particular area, automation system 100 may query the user to input the plant type and/or required levels of light. In addition, automation system 100 may research databases (e.g., internet plant databases) to retrieve lighting requirements for particular plants. Based on the required lighting levels for the identified plants, control 110 may open and close window coverings via controller 160, step 504. For example, the window coverings may be operated to stay open during a portion of morning and evening hours so as to provide appropriate light for the health of the plant.
In another embodiment, automation system 100 may be configured to control various systems within a home based on, e.g., energy action days. Energy action days are typically days designated by authorized local utilities or governments to promote conservation of energy. In particular, on energy action days, citizens may be encouraged to conserve energy due to high peak demands or high costs of fuel.
During designated energy action days, automation system 100 may receive an indication of the energy action day from the internet 140 over a network connection 150. In addition, a user may selectively place automation system 100 in an energy action mode. Upon receiving indication of an energy action, control 110 may order controller 160 to close window coverings partially or fully to reduce the heating load on a heating and/or cooling system, thereby reducing the energy consumption. In the above example of plants, e.g., a response to an energy action day may override preexisting programs/instructions, such as, e.g., an instruction to open window coverings at 2 pm each day to provide light for plants.
An indication of an energy action day may also cause control 110 to restrict other actions. For example, appliances such as dishwashers, clothes washers, and clothes dryers may be restricted to operate in hours designated as off peak, such as, e.g., between 6 pm and 6 am. In another example, an outlet 300 controlling a pool pump may be energized only at night, thereby restricting operation of the pool pump to off-peak or night hours. In a further example, control 110 may be connected to a thermostat controlling air conditioning and heating systems, which may be adjusted to reduce energy consumption during energy action days. Control 110 may be also connected to a hot water heater or boiler, which may be controlled to reduce the temperature or frequency of operation during energy action days. Further, control 110 may be connected to television or monitors and may reduce the brightness of the display to save energy or disable some of these devices in response to the control 110 receiving an indication of an energy action day.
In another embodiment, control 110 may monitor costs of energy, which may increase or decrease at different times of the day or during different periods of the year, as well as monitor for energy action alerts. By monitoring the pattern of energy drawn by a particular electrical device, e.g., control 110 may be able to identify particular operations or cycles. For example, a dishwasher may consume power at a first rate during the wash cycle, which involves running the pump and agitator, and consume power at a second rate when the heated dry cycle is active. Based on this information, control 110 may shut off an appliance after a particular cycle is complete in response to a change in energy cost, an energy action alert, or another input, The device may be then re-activated by control 110 to finish operation after the energy action alert expires or after the time of day advances till the energy cost is lower. Such control may optimize electrical device operation to minimize utility cost to the user and to minimize energy usage during, e.g., an energy action alert or during peak usage hours, without, e.g., stopping an appliance in the middle of a cycle. Allowing a cycle to finish resolves the sub-optimization of, e.g., stopping a dishwasher partially through a wash cycle, which may result in the entire wash cycle needing to be repeated, which would ultimately increasing energy usage.
In another exemplary embodiment, an irrigation system (not shown) may be coupled to an outlet 300 of the present disclosure. Automation system 100 may be configured to receive weather data as explained herein. Based on such data, and based on user input, automation system 100 may be configured to terminate power delivery to the irrigation system during and immediately after periods of heavy rainfall. Similarly, power to the irrigation system may be enabled during periods of drought or irregularly high temperatures. Furthermore, automation system 100 may be used to ensure compliance with a predetermined utility budget. For example, a user may program automation system 100 to only permit the irrigation system to irrigate up to a predetermined utility cost (e.g., $200.00 per month). In addition, the user may program automation system 100 with the cost of certain utilities (e.g., water and electricity). Thus, once the irrigation system has delivered water matching the cost of the predetermined budget, automation system 100 may terminate delivery of power to the irrigation system.
In another exemplary embodiment, automation system 100 may be used to control a plurality of valves within a home or other suitable structure. For example, a home may be provided with electrical valves for controlling the supply of water to, e.g., a washing machine, a dish washer, and a shower. Based on sensed usage (e.g., power consumption) or historical data, automation system 100 may automatically open and close certain valves to maintain optimal water pressure. For example, if automation system 100 detects that both a washing machine and dishwasher are simultaneously running, automation system 100 may close the valve to the washing machine until the dishwasher has completed its wash cycle. Alternatively, if automation system 100 detects a user in a shower (via, e.g., a motion sensor), automation system 100 may close the valves to the dishwasher and washing machine, to ensure the user receives optimal water pressure in the shower. The principles of maintaining water pressure, as well as the other principles disclosed herein, may be applied to multiple automation systems 100 controlling a plurality of discrete structures.
In an even further example, automation system 100 may selectively activate and deactivate a home hot water heater. For example, during summer months, automation system 100 may limit the energy delivered to a hot water heater, or limit the periods during which energy is delivered to the hot water heater. In the winter months, however, automation system 100 may increase the energy delivered to the hot water heater and/or increase the periods of time within which energy is delivered to the hot water heater.

At step 710, e.g., automation system 100 may monitor power consumption and noise in the associated power lines to determine if a portable battery charger is connected to any outlet 300. Once identified, automation system 100 may subsequently monitor the power consumption characteristics to determine if the charger is currently charging a battery, step 720. If a device is not being charged, the outlet may be temporarily disabled to reduce power consumption typical of chargers not in use (e.g., vampire or phantom loads), step 730. In one embodiment, the outlet may be re-enabled periodically, e.g., every 15 minutes or other suitable time integral, to determine if a device to be charged has been attached to the charger. The outlet may optionally be enabled if motion is detected (via, e.g., a motion sensor) indicating a person is in the vicinity of the charge.
If, however, automation system 100 detects that a device is being charged at step 720, automation system 100 may monitor the power consumption of the charger until it determines that a charging cycle is complete. At this time, automation system 100 may terminate the power delivered to the charger, step 740.
In one embodiment, automation system 100 may be configured to periodically “top-off” a portable battery without leaving the charger energized full time. For example, the charger may be re-enabled if motion is detected in the room (via, e.g., a motion sensor). Such motion may indicate a user awaking in the morning. In this manner, the charged device may be “topped-off” prior to the user retrieving the device from the charger. In another example, automation system 100 may track when the user typically retrieves the device from the charger by storing statistics on when the charger's power consumption characteristics change to indicate no device is being charged. If the historical data is available, automation system 100 may turn the charger outlet back on approximately 15 minutes prior to the historical time the device is typically disconnected to allow the device to be “topped-off.” Alternately, the charger may be enabled every 30 minutes to allow the charger to top-off the device battery routinely. This method provides the benefit of reduced energy consumption by disabling the charger whenever possible, but still providing fully charged devices.

Control 810 may be also connected via wired or wireless connection 815 to a switch 820. The switch 820 may be operated to control, by wired or wireless connection 835, the operation of outlet 830, or another outlet coupled to the system 800 (not shown). System 800 may include a plurality of switches 820 and outlets 830. As explained above, switch 820 may also include sensors such as motion sensors, thermometer, camera, light sensors, or other sensors known in the art and described above. In addition, or alternatively, the sensors (not shown) may be operably coupled directly to system 800. The data from the sensors may be communicated via connection 815 to the control 810. Remote outlet 830 may be controlled by a signal delivered via, for example, connection 818 or connection 835. Outlet 830 may monitor the characteristics of the power consumed by the device attached to it, and can modify the power delivered to the device, including, e.g., enabling power, disabling power, or otherwise adjusting (e.g., reducing) the power delivered.
In the depicted example, a fan 880 may be connected to the outlet 830. The fan is operable to circulate air in an area of the building providing improved comfort for persons in the area served by the fan.
The control 810 may monitor the power consumed by the fan 880 and determine that the device is a fan, as described above. The characteristics of the consumed power and noise generated can be monitored by outlet 830, and the data may be compared with algorithms stored in 810 or with data stored in the cloud 840 to determine the identity of the fan, as described above.
In addition, the control 810 may determine that users are present in the vicinity of the fan from data gathered from the sensors (e.g., a motion sensor) associated with system 800. Further, a camera associated with system 800 may provide pictures, which can be analyzed to determine the presence of persons.
If control 810 determines that users are present in the vicinity of the fan, then control 810 may send signals to the HVAC controller 870 via connection 823 to reduce the amount of energy consumed by the HVAC. This may be done by, e.g., setting the air conditioner to a higher temperature, reducing the temperature of the heat setting, or by running the HVAC less often. Since it is likely that the person in the presence of the fan will still be in a comfortable environment. Thus, the automation system will control a first device based on an operating characteristic of a second device.
If automation system 800 detects that the fan is later turned off or unplugged, the control 810 would receive information that the fan is no longer operating, and the HVAC controller may be sent a signal to modify the HVAC setting to increase operation, since the fan will no longer be providing air circulation. Similarly, if a second fan (not shown) is plugged into any associated outlet 830 near first fan 880, the controller 810 would receive information from outlet 830 indicative of the presence of a second fan, which may cause the controller to further modify the HVAC controller 870 to further reduce operation and save energy.
Further, if the control 810 determines that there is no one in the vicinity of the fan 880 from sensor data gathered from switch 820, the control 810 may send a signal to shut off power to the fan by terminating the energy delivered to outlet 830. Similarly, if a person enters the room, which may be detected by a motion sensor, the control 810 send a signal to re-enable the power to the fan 880 at remote outlet 830.
In another embodiment, automation system 100 controlled by control 110 may determine that a pump (not shown) is connected to one of the outlets 130. Operating statistics such as, e.g., run time and power consumed, may be collected by control 110. In addition, control 110 may obtain weather information from the internet via a weather service, or from sensors connected to the control 110. If the operation of the pump deviates from the normal or historical trends, a message would be sent by control 110 to a designated user or an alarm may be generated, as discussed above. For example, if a sump pump was running continuously without rain, a message would be sent so the pump could be investigated. Possibly the pump sensor has malfunctioned causing the pump to run continuously wasting energy and hurting the reliability of the pump. Similarly, if the pump is not running during heavy rainfall, a message would also be sent.
