Description

FIELD OF THE INVENTION

The present disclosure relates to thermostat update systems for transmitting update data between thermostats, remote devices, and/or the cloud.

BACKGROUND OF THE INVENTION

The adjustment and setting of thermostats and the programming that exists with such thermostats determines how HVAC equipment is modulated and for what duration the equipment should run. Many thermostats have complex and confusing controls requiring a great deal of time to program. Individuals who receive new thermostats often have difficulty navigating the complexities of thermostat settings.

Furthermore, in buildings with multiple units, there are often multiple thermostats that require programming. In situations where installers must manually program each thermostat, setting up the thermostats can take a significant amount of time and there is a high likelihood that mistakes will be made.

What is needed is a thermostat update system that circumvents such difficulties by allowing for updated data to be quickly and accurately transferred from one thermostat to another, either directly or through a series of intermediary devices.

DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS

The set-up and update of thermostats can be a time consuming and non-intuitive process. For example, in a multi-unit dwelling with dozens to hundreds of similar thermostats, the opportunity for error during the configuration process multiplies quickly. Therefore, it can be desirable for an installing contractor to configure one thermostat and copy the correct update to a plurality, if not all, of the remaining thermostats. In some embodiments, it can also be desirable to update a plurality, if not all, of the thermostats to the latest software version.

Wi-Fi connectable thermostat “thermostat” is used to refer to a comfort control device. In addition to a traditional thermostat, the control device could be, among other things, a humidistat or ventilation controller.

In some embodiments, a thermostat can include a transceiver. In some of these embodiments, a thermostat can broadcast a signal, and in certain embodiments the signal is a Wi-Fi signal detectable by transceivers in Wi-Fi enabled devices.

Traditionally when Wi-Fi thermostats are first connected to the internet, the thermostat is placed in AP (Access Point) mode (wherein the thermostat broadcasts a signal detectable by a Wi-Fi device) and a Wi-Fi password is transferred to the thermostat from a tablet, computer, smartphone, or other Wi-Fi enabled device. The thermostat then tries available networks (often in order of decreasing signal strength) to attempt to gain a successful connection to the internet. This process is outlined in U.S. patent application Ser. No. 14/920,188, which is incorporated herein by reference.

In some embodiments in which each thermostat is not directly connected to the internet, information can be transferred from one AP (access point) connected thermostat to other thermostats in a thermostat network. The copy or update function can take place at the installation site, while still at the installing contractors facility, during the manufacturing process, or somewhere else along the process from manufacture to installation.

A thermostat update system can comprise, among other things, a Wi-Fi connectible thermostat, a processor, a transmitter, and a storage area. In some embodiments, the transmitter can transmit update data to multiple target devices, which can include, but are not limited to, mobile devices having applications configured to receive the update data or fixed devices which can be activated.

A thermostat update system can comprise, among other things, a first thermostat having a processor, a transceiver and a storage area. In some embodiments, the processor generates update data for the thermostat and the storage area maintains the update data. In some embodiments, the transmitter can transmit update data to multiple target devices, including at least one mobile device capable of running an application to receive update data and memory, as well as a second thermostat. A control button on at least one thermostat can be activated in order to transmit update data to the mobile device and/or additional thermostats. In some embodiments, the mobile device is capable of displaying the update data from the first thermostat. In some embodiments, the first thermostat can include at least one of a stand-alone thermostat and a thermostat combined with other components providing environmental controls for a building.

In some embodiments, a touch pad and/or built in contact mouse is provided by a display of the first thermostat in order to transmit the update data. In some embodiments, activating the remote device of the first thermostat enables transmission of the update data to a third thermostat. In some embodiments, the second thermostat is capable of transmitting the update data to a third thermostat. In some embodiments, the update data is transmitted to a Wi-Fi router and the Wi-Fi router sends the update data to the second thermostat.

Example uses of the thermostat update systems and methods provided are provided below.

When constructing single and multi-family dwellings, a builder usually installs a Wi-Fi thermostat with heating and cooling equipment prior to the resident moving in. Often a dwelling sits vacant while units are finished, rented and/or sold. After the resident moves in, the Wi-Fi thermostat can be registered and connected when the resident contracts with an internet provider and internet access equipment is activated. In such instances, it is beneficial to have a thermostat with update and copy capability before the dwelling has internet access available. This capability can be made available by sending non-registration update information from a web server, such as the BlueLink® Smart Data server, to an internet connected smartphone, computer, and/or tablet, to an AP (Access Point) enabled thermostat. Copy information can be sent from copy source AP enabled thermostat to the smart phone then to the copy target AP enabled thermostat. In some embodiments, the copy information can be send from copy source AP enabled thermostat directly to copy target AP enabled thermostat.

While the above example is directed towards dwellings for purchase and later occupation by individuals, there are also a variety of reasons why a thermostat system would not be updated when installed, including: transitionally available internet access such as mobile hotspots, and local, state or federal laws and regulations that may prohibit unattended active radio devices.

In at least some embodiments, a thermostat update and copy system operates by transmitting data over ad-hoc wireless networks. In certain embodiments, these networks are short wavelength radio wave networks, such as Bluetooth networks. In ad-hoc embodiments, a transceiver on a first thermostat can connect directly to transceivers on other devices. These other devices need not be connected directly to the internet, or to other wireless networks. In at least some embodiments, the ad-hoc thermostat network is capable of transmitting authentication information for wireless networks from a single device having such credentials (such as a mobile device, server, wireless router, or computer) to other thermostats within the network. Illustrative thermostats in the thermostat update and copy system are further illustrated in FIG. 10 and indicated at 1002, 1004, 1006, 1008 and 1010.

In some embodiments, the ad-hoc network can be self-developing, wherein a first device in the network need not be in range of an internet access point. Instead, when the thermostat enters AP mode, it can seek other thermostats and devices to connect to. In some embodiments, the thermostat will connect to other AP enabled thermostats automatically. Each of the thermostats in this network can then connect to other thermostats and devices, until one such thermostat or device has access to a Wi-Fi or hardline enabled internet connection. The device which acquires this connection can receive authentication to access the internet, and then proceed with an updating sequence. This update can then be spread throughout the ad-hoc network to other AP enabled thermostats. This type of networking has several advantages, namely that the thermostat to initiate the update sequence need not be within range of a wireless network. This is particularly helpful for large networks of thermostats, wherein an installer can be unsure as to which thermostat has the best connection opportunity to proceed with an update sequence. The self-developing connections in the ad-hoc network and data transmission are further illustrated in FIG. 11 and indicated at 1102

In an ad-hoc thermostat network, the thermostat having the strongest connection to the internet can be selected automatically to proceed with the update procedure. Once the update is acquired, the update can spread to other thermostats and devices within the network.

In some embodiments, and ad-hoc thermostat network is capable of self-developing, wherein each thermostat will automatically connect to other thermostats in the area. In some embodiments, this network is pre-determined. For instance, a manufacturer, contractor, or individual maintaining the thermostat network can specify which units are to be part of the network. In some embodiments, a user can specify a host thermostat having a Wi-Fi connection, from which updates will disseminate. In other embodiments, a user can instruct a thermostat network to self-determine the thermostat of best connection for each update. In certain embodiments, the update sequence for a thermostat network can be controlled from a third-party device, such as a mobile device with wireless capability. In other embodiments, the update sequence can be controlled from a specific thermostat, or from any thermostat in the network.

In some embodiments, each thermostat in a network will have at least one hard button and/or at least one soft button. In some embodiments, a thermostat can have a network access port, such as a CAT-5 port. In embodiments comprising ad-hoc thermostat networks, a thermostat with a CAT-5 connection or similar wired internet connection can be specified as the update host thermostat.

In some embodiments, a network of thermostats can be monitored and configured using software on a device which can be connected to the thermostat network when in range, such as a smartphone. In other embodiments, a thermostat network can be configured using an on site or off site device in internet communication with at least one thermostat in a thermostat network.

In some embodiments, the networked device in communication with the greatest channel capacity is used as a host device. In at least some embodiments, channel capacity is defined according to Shannon's formula, given as:

$C=B({\log }_x\left(1+\frac{S}{N}\right)$

wherein C is the channel capacity, B is the bandwidth, S is the signal, N is the noise, and in some embodiments x is equal to 2. In other embodiments, host determination can involve quantities from Hartley's law, the Nyquist rate, or other calculated or measured quantities known in information or data transmission theory. In other embodiments, expanded versions of Shannon's formula can be used. In some embodiments, an ad-hoc network is developed to minimize the path attenuation between thermostats. In some embodiments, each thermostat has an individual IP address, and in some embodiments this address is known by devices connected to the thermostat network. In some embodiments, a network of thermostats can be configured to automatically receive updates.

In some embodiments, a thermostat network can be configured to update when temperatures surrounding the thermostats in the network are at their lowest in a specified period of time, to maximize network performance and data transfer rates. In other or the same embodiments, updates can occur at times specified by a user on at least one device connected to a thermostat network.

In some embodiments, all thermostats default to being in AP mode. In at least some of such embodiments, AP mode thermostats are programmed to seek connections with other AP mode thermostats. In at least some of such embodiments, AP mode thermostats are configured to seek connections with wireless communication enabled devices. In certain embodiments, thermostats will seek connections to other thermostats with a higher priority than connections to other devices, and will then seek connections with other devices once a stable network of thermostat connections has been established. In some embodiments, a user can leave a thermostat network open, allowing authorized devices to access the network at any time. In other or the same embodiments, a user can close a network to non-authenticated devices.

In certain embodiments, a user is able to specify the particular thermostat units in a given thermostat network.

In some embodiments, each thermostat in a thermostat network has unique authentication credentials. In some of such embodiments these credentials can be stored on storage devices provided within thermostats. In other or the same embodiments, a master list of authenticated thermostats can be stored on a remote device, such as a server. In such embodiments, a user can access and modify this list using devices in communication with said storage device, such as mobile devices or computers. In other or the same embodiments, all properties for a thermostat network can be configured from a single thermostat in the network.

Some embodiments of the system and method disclosed are shown in FIGS. 1-8. In some embodiments, the thermostat update system enables thermostat configuration and programming data to be copied from a source thermostat to at least one target. In some embodiments, the thermostat update system allows thermostat firmware update data to be transferred through a smartphone to another thermostat. This firmware can, among other things, reside as part of an app, be downloaded from a webserver, and/or contained on a device connected to the thermostat update system via a wired or wireless connection.

Turning to FIG. 1, thermostat update system 100 includes remote device 110. In some embodiments, remote device 110 is a smartphone or tablet that includes screen 115. In some embodiments, screen 115 can be used as both a display and an input device for thermostat update system 100. In some embodiments, input can be via a qwerty key pad that is displayed on screen 115 and/or via other means such as a mouse or attached keyboard (not shown). Remote device 110 can include telecommunications standard transmission means such as 4G transmission or Wi-Fi transmission via internet 120.

In some embodiments, remote device 110 transmits to Wi-Fi router 125 within a building where the targeted thermostat is located. Wi-Fi router 125 can communicate with transceiver 132 located within thermostat 130 (see FIG. 8). Thermostat 130 can include, among other things, on/off switches 134, display 136, touchpad 138 and microprocessor 139. Thermostat 130 can control HVAC system 140 and/or other climate control system(s).

In some embodiments, such as the one illustrated in FIG. 1, microprocessor 139 of thermostat 130 is programmed to transmit data regarding the operation of thermostat 130 upon user input. In some embodiments, the transmission of the data in is via transceiver 132 and Wi-Fi router 125 to internet 120.

In some embodiments, a cloud server can collect and organize update data being transmitted from thermostat 130. In at least some embodiments, remote device 110 and/or other devices that are linked to internet 120 can obtain the update data from cloud server. The update data can be stored in physical memory. The physical memory can be located, among other places, in thermostat 130, Wi-Fi router 125, or other devices connected to thermostat update system 100. In some embodiments, a request for the update data can be processed by microprocessor 139 by sending the update data directly to requesting remote device 110 or another thermostat (without use of a cloud server).

FIG. 2 depicts a schematic diagram providing an overview of a potential paths for data transmission. The embodiment show in FIG. 2 provides for the transmission of update data 205 to and/or from first thermostat 230A to and/or from first remote device 210A, second remote device 210B, and/or second thermostat 230B.

In some embodiments, first thermostat 230A is programmed to set the update data. Update data can include mode and function settings of thermostat 230A, including, but not limited to, temperature setting(s), time of day setting(s), day of week setting(s), programming set point(s), installer setting update(s), user setting(s), device identification information, Wi-Fi router interface data, Wi-Fi router identification data, mobile device identification data, source(s) of input(s) for temperature, source(s) of input(s) for relative humidity, discharge temperature, outdoor temperature, stages present, cooling response, lock-out, set point degrees, auxiliary stages, heat response, scheduling data, energy management setting(s), recovery setting(s), uploader and downloader update setting(s), internet communication setting(s), configuration data, and/or other relevant data to the operation of a thermostat update system such as thermostat update system 100. Update data can be programmed directly at first thermostat 230A and/or remotely, such as by remote device 210A and/or remote device 210B. Remote devices 210A and 210B can be, among other things, smartphones, tablets, computers, and/or laptops.

Once first thermostat 230A is configured it operates HVAC control relays 240A to manage the environment of the building. In some embodiments, control button 854 (“CONFIG”) (see FIG. 8) on first thermostat 230A can be activated to transmit update data 205 to Wi-Fi router 225A. In some embodiments, Wi-Fi router 225A can transmit update data 205 to remote device 210A, remote device 210B and/or Wi-Fi router 225B. Update data 205 can then be transmitted to second thermostat 230B.

In some embodiments, second thermostat 230B can be located in a second building adjacent to a first building housing first thermostat 230A. In some embodiments, a plurality of thermostats is in a single building/complex. In such environments, first thermostat 230A can transmit update data 205 to each of thermostat in the building via a process similar to that discussed above in regard to second thermostat 230B. As shown in FIG. 2, first thermostat 230A is the source for update data 205 and second thermostat 230B is the target.

In some embodiments, second thermostat 230B can become the new source of update data 205 and a third thermostat (not shown) can become the target. In such an example, second thermostat 230B can transmit update data 205 to the third thermostat (not shown). Remote devices 210A and 210B can be used to supplement the operation and/or can be used to alter update data 205 and/or update settings of a plurality of the thermostats. In some embodiments, once a target thermostat receives update data 205, it is then capable of controlling the environment via a corresponding HVAC control relay.

FIGS. 3 and 4 illustrate examples of thermostat update and programming data being copied from a source thermostat and transferred to a target. As is true throughout the entire application, unless otherwise specified or necessitated by logic, the various methods are not limited to the order in which the steps are described.

Method 300 can provide an AP copy to facilitate data transfer directly from the remote device to the thermostat without the need for a working Wi-Fi connection.

At 301, a Management App is downloaded to a remote device, such as a smartphone or tablet. At 302, a first thermostat (Thermostat 1) is installed and provided with power. At 303, Thermostat 1 is configured and programmed for the installation. At 304 Thermostat 1 is placed in AP (access point) mode.

At 305, Management App (MApp) is started. In some embodiments, Management App includes a user login process. At 306, a user selects a copy function and selects Thermostat 1 as the source from which material is to be copied. In some embodiments, 306 is accomplished using Mapp. At 307, update and/or programming data is transferred from Thermostat 1 to a remote device such as a smartphone via AP communication. At 308, update and/or programming data are stored for later retrieval.

At 309, the user installs a second thermostat (Thermostat 2) and provides power to Thermostat 2. At 310, Thermostat 2 is placed into AP mode. At 311, a user selects a copy function and selects Thermostat 2 as the copy target. In some embodiments, 311 is accomplished using MApp. At 312, update and/or programming data is/are transferred from a remote device, such as a smartphone to Thermostat 2 via AP communication. At 313, Thermostat 2 is placed into service. In some embodiments, at 314 thermostat firmware update data can be transferred through the remote device such as a smartphone to the thermostat or additional targets when appropriate.

Turning to FIG. 4, AP update process 400 is described according to some embodiments. At 401, a Management App is downloaded to a remote device such as a smartphone or tablet. At 402, a first thermostat (Thermostat 1) is installed, provided with power, and configured/programmed. At 403, Thermostat 1 is placed in AP (access point) mode. At 404, Management App (MApp) is started. In some embodiments, MApp includes a user login process. At 405, user selects an update function and selects Thermostat 1 as the update target. In some embodiments, 405 is accomplished using Mapp. At 406, Thermostat 1 is queried to determine whether its software is the most current version.

In some embodiments, at 407 the MApp determines that Thermostat 1 does not have the latest firmware update (in FIG. 4 the firmware version is a lower/previous version). At 408, MApp notifies a user that an updated version of the firmware is available and obtains permission from the user to update. At 409, the App retrieves model specific firmware from the cloud and/or internet. At 410, the remote device downloads the updated firmware from an internet source. In some embodiments, the firmware is downloaded via a LTE or Wi-Fi connection.

At 411, the remote device puts Thermostat 1 in updated AP mode. At 412, the updated firmware is transferred to Thermostat 1 from smartphone via AP communication. At 413, Thermostat linstalls firmware updates. In some embodiments, Thermostat 1 restarts as part of the update process at 413. At 414, the user closes the MApp and/or proceeds to the next thermostat for updating where appropriate.

Turning to the example screen shots, FIGS. 5-8, the target thermostat displays the word “Copy” as shown in FIG. 5. The step can also include the “Next” and “Return” buttons also being displayed. The following step, has the installer pressing the “Next” button at the target to help ensure the user has selected the correct target thermostat and start the copying function. The target thermostat displays a “Wait” alphanumeric display as shown in FIG. 6. The target thermostat retrieves the source configuration from the remote device, cloud, or via Wi-Fi router 320 (FIG. 2). The target thermostat 310 loads the source configuration into the target thermostat non-volatile memory or another storage location. The target thermostat 310 displays the alphanumeric symbol for “DONE” as depicted in FIG. 7. In the event that the configuration data fails to load to the target device, the display would provide a “FAIL” message (FIG. 8) and appropriate diagnostic codes to facilitate troubleshooting error messages.

FIG. 9 depicts a first embodiment of thermostat 900 configured to be used in a thermostat update system such as the one depicted in FIG. 1. In some embodiments, thermostat 900 can include control buttons such as update touch pad 954 and/or hard button 920. The control button(s) can be used to transmit update data to another device as discussed above. Other features of thermostat 900 can include Temperature Icon 910, alternative touch pads 930, for functions such as CLEAN, HUMIDITY, OUTDOOR, SYSTEM, FAN PROG, HOLD DAY/TIME and fan icon 940. The thermostat can be similary constructed with only control buttons, control buttons and a touch screen, or only a touch screen.

While particular elements, embodiments and applications of the present invention have been shown and described, it will be understood, that the invention is not limited thereto since modifications can be made by those skilled in the art without departing from the scope of the present disclosure, particularly in light of the foregoing teachings.
