DETAILED DESCRIPTION OF CERTAIN EXEMPLARY EMBODIMENTS

A configuration of an exemplary embodiment is depicted in FIG. 1.
AC to DC Converter
This power converter may step down the 24V AC provided from the heating/cooling power lines to the correct DC voltage needed to run the apparatus and keep the backup battery charged and on standby.
Temperature and Humidity Sensor
The temperature and humidity sensor allows the apparatus to serve as an additional sensing zone. This data can not only be used in heating and cooling the home but also can be used to drive other aspects of the smart home.
HVAC 24V Control Signal Emulation or Switching
This is the control center of the apparatus. This solution may route 24 v via relays or emulation to the appropriate relays on the HVAC system. Those skilled in the art may appreciate that cost and efficiency may be the driver on selecting specific Relays or Emulation for signaling the 24V HVAC Control relays. 24V applied to Y1, for example, may turn on the Cooling system.
Wire Terminals
Wire terminals allow the installation process to be quick and easy. Wires from the HVAC system are connected to the corresponding terminals by inserting wires in to the corresponding holes. This type of connector allows for easy insertion and removal of wires should the need arise.
Backup Battery (Example: Rechargable Lithium Ion CR2450 3.6 v, or Lithium Ion Flat Pack)
This battery may be charged by the converted 24V AC coming in off of the HVAC system and may stand in should voltage not be adequate enough to run apparatus. Those skilled in the art will appreciate that any suitable batteries or other power source may be used instead of Lithium ion batteries.
Zigbee Module (Example: Silicon Labs: EM357 Ember)
Using a Zigbee module for communication between The apparatus and external control devices, such as a controller, hub, or an app interface, allows for easy exchange of data and control. The module also acts as a passive extender for other Zigbee modules allowing the overall Zigbee network to increase in coverage area.

Exemplary Design
The apparatus is designed to replace an existing thermostat, or in the case of new homes, be wired directly to an HVAC system, thus eliminating the need for expensive copper wiring.
The apparatus may comprise 2 parts: (1) a wiring plate, which gets mounted to the wall and has terminals to accept the wires which control the HVAC system, as well as the front face; and (2) a face plate, which houses the electronic components and is the consumer side of the product. See FIG. 2.
An exemplary embodiment is currently sold as the “Wink Norm”, by Wink Inc., and is described at http://www.wink.com/products/quirkyge-norm-thermostat/.
The faceplate of the apparatus, once wired up, attaches directly to the wiring plate, concealing the wires behind.
Exemplary Installation:
Physical Installation:

- 1. Remove old thermostat faceplate from the wall.
- 2. Mark existing wires with their current positions using the included labels.
- 3. Dismount wires from old wall plate.
- 4. Remove old wallplate.
- 5. Pull wires through base plate and mount the plate using included drywall screws.
- 6. Match each wire to its corresponding wire terminal and insert wire.
- 7. Snap faceplate onto the base.

Setting up from a Controller
A multi-device controller such as that described in co-pending U.S. patent application Ser. No. 14/667,127, entitled “CONTROL APPARATUS AND RELATED METHODS”, may be used with one or embodiments. More details on such a controller are provided below in the Exemplary Controller section.
From any control screen on the Controller, tap on settings.

- 1. Tap Devices and you should see a list of all registered devices on top and newly discovered devices below.
- 2. Locate the new apparatus in the bottom list and tap it.
- 3. Your Controller may register your new apparatus and add it to your Wink account.
- 4. You are now able to interact with the apparatus from any Controller or device running the Wink app.

In-App User Interface
Controlling the apparatus (designated “Project 2” in FIG. 3) from within a Wink app preferably is simple and intuitive. Building off of the platform's ability to utilize the back end for creating schedules, the user may be presented with a simple interface to view and adjust temperature manually, as well as fine tune schedules.
The interface may allow for easy control of multiple zones by allowing the user to select which room they want to base temperature on, as well as which zone they are controlling in manual mode. The remote sensor for the thermostat may be the temperature and humidity sensor in the light switch (Controller) described above, and/or sensors in other products.
If a user has light switches in the dining room and bedroom, these would know the temperature in each room, and the thermostat may cool or heat more based on which room has priority. This priority also may be based on a user's location in the home (as determined by cell phone, motion detection, etc.). The thermostat itself also has a temperature and humidity sensor and thus may correspond to its own heating/cooling zone.
Scheduling may be a quick and painless activity for the user. The user may use a slider to select the room, temperature range, and time for this range to be active.
Historical usage data may also be available to the user from within the Interface.
In an embodiment, the device comprises an accelerometer, and the interface may be set up so that, for example, 1 tap=4 degrees cooler (blue light) and 2 taps=4 degrees warmer (red light). An RBG LED may be used to reflect the different colors.
Screen Descriptions (see FIG. 3)
Main Screen
The Main Screen may show basic information about the apparatus's current status. This may include the current temperature setting, ambient temperature in the heating/cooling zone the apparatus is installed in, and the current operation mode. If there are multiple apparatuses installed, the current temperatures of those may be included also. The home screen may also allow the user to toggle basic settings. These may include the mode that the apparatus is in—either heating, cooling, or fan only—and adjusting current temperature setting either hotter or colder.
Schedule
The Schedule screen offers a glimpse into how the HVAC system is going to be operated over the span of a specified time frame and allows a user to make adjustments based on preference or upcoming schedule.
Since the apparatus may be on the Wink ecosystem, and tied together with sensors throughout the home, a schedule may be automatically created and adjusted in real time based on user habits and desired temperatures.
Add a new scheduled event:

- 1. Select Schedule from the Main Screen
- 2. Click the + icon to add a new event which brings up the Event Detail Modal screen.
- 3. Adjust the desired day and time the event should occur and if it should recur.
- 4. Set the desired temperature set point for that time.
- 5. Close the Event Detail Modal.

Edit a Scheduled Event:

- 1. Select Schedule from the Main Screen.
- 2. Tap on the scheduled event to edit which pulls up that event's Event Detail Modal.
- 3. Make adjustments to day/time or temperature.
- 4. Close the Event Detail Modal.

History
The History screen offers a glimpse into the user's heating and cooling usage. This information is easy to drill down by month/week/day and offers the user insight into how their schedules are being automatically created and the times at which their system is being most utilized.
Further exemplary details are provided in TABLE 2 below.

Central Processor—Host (Freescale i.MX6)
This board allows the system to run Android as the underlying OS and launch a custom build of the wink app. This app may be catered to this application but allow for the addition of all products compatible with the wink ecosystem.
System Memory—Host

- DDR3 512M×64
- NAND Flash 2 GB
- Serial NOR FLash 4 MB

4.3″ Capacitive Multi-Touch Screen [MRD-DISP-001]
The central interaction point of the product, the touch screen is where most of the interaction happens. With a personalized dashboard as a user default, a quick touch switches to the switch screen, allowing control of the local loads the switch replaced, as well as any other components.
Bluetooth/WIFI Combo Chip (Semco SWB-B53 Based on Broadcom BCM4334)
[MRD-SW-002]
Not only providing the connectivity of the unit, this chip allows for Bluetooth and BLE connectivity which opens up an entire new spectrum of products the Wink platform can take advantage of.
Bluetooth, while as stated, allows control of other products, it may also allow other Bluetooth devices to control the light switch.
BLE allows the system to serve custom experiences based on who is standing at the panel, as their phone will be recognized.
The WIFI capability provides for connectivity to the Internet via a local router.
Zigbee Module (Silicon Images EM357 Ember)
[MRD-SW-003]
The use of Zigbee enables support for existing products such as wireless light bulbs (Philips Hue, etc.) as well as development of future products. The use of Zigbee also acts as a passive extender for other Zigbee products the user may already own, thus increasing the range in which their existing products work with each other.
2×Momentary Switches
These switches can control the local loads on them (the lights a user switches were tied to) and also can be configured to control virtually any smart product that reacts to on/off etc. (Garage Door, Smart light bulbs located anywhere [and not just one], Pivot Power Genius). The satisfying click lets a user know the button was pressed and is a quick way to interact with a user's home without having to interact with the screen if a user is on the go.
Motion/Prox Sensor
[MRD-INP-001]
The IR Sensor is how the switch knows a user is coming up to interact. This gives the switch time to wake up and provide a user with the info or control a user needs immediately without a user having to waste time waking the unit up. Those skilled in the art will appreciate that any suitable motion or position sensor may be used instead of an IR sensor.
2×Solid State AC Relays
The A/C Relays are switches. The switch is wired to replace 1 or 2 switches with the same SKU. The Relay, when given the signal, switches the local loads on and off. This signal can come from the local buttons, the touch screen, or any other device running the wink app.
AC/DC Converter
The converter may be how the apparatus is powered. The AC power from the gang box is converted to DC.
Temperature & Humidity Sensor
With the inclusion of temp and humidity sensors, a user has more data about their home at their fingertips.
Microphone
[MRD-INP-003]
The microphone gives control opportunity as well as the ability to incorporate an internal intercom system. Voice commands may be used, and other sounds may be recognized (doors opening/closing, dogs barking, etc.).
Speaker
[MRD-OUT-001]
As with the microphone, the speaker may allow for intercom operability as well as give the device a personality and voice, as well as reminders and audible alerts.
