＊ Nest Owners, please note that this app will work for you if you are on a Nest account (even if you use a Gmail email to log into it). In that case, it lets you log in even after the September 1st 2019. Right now it does not support login with a new Google account. Support for Google accounts is coming soon. Note also that if you are on a Nest account, migration to Google account is not mandatory.
＊ The app has Siri Voice shortcuts for seamless Siri control of your Nest, from the iPhone, Watch and HomePod. It fully supports Apple Watch LTE, and can work when the iPhone is not around - as long as the watch itself has internet access (either LTE or WiFi).
＊ The app lets you monitor and control HomeKit thermostats like Ecobee, and functions largely the same with them as
it does with Nest, except for the Siri Shortcuts functionality which is not needed with HomeKit.
• Using Siri voice shortcuts you can control many aspects of your Nest, such as instant activation of heating or
cooling, direct setting of your favorite temperatures, increasing/decreasing the temperature, and setting the Home/Away

• From the watch face, tap on the Thermo Watch complication to open the app. Spin the Digital Crown, or Swipe up/down to adjust the temperature. You can start adjusting the moment the app opens.
• On your iOS device you can press firmly onto the app icon to open a quick popout menu, you can swipe to the notification center to adjust the temperature on the Widget, or you can just open the app. Again, you can start adjusting the moment the controls appear.
• From your Apple TV, open the app, and swipe up/down on the remote to change the temperate.
The app will let you know with a chime and a tap, that the thermostat has received and applied your command.
Monitor your Thermostats and Home/Away status right from the watch face, using complications that update in the background, without having to launch the app.
You can use Siri on your iPhone, Watch, iPad, or HomePod to control any of your thermostats. Record phrases that make most sense to you, such as "Start Heating" or "Make it Cooler". If you have multiple thermostats you can control them individually, by saying for example "Start Heating Upstairs" or "Start Cooling the Living Room".

The app supports multiple thermostats in multiple homes - just swipe left and right on your Watch screen to access them, or see them all at the same time in the iOS Widget and the app. Fahrenheit and Celsius are both supported.
Beyond that, you can press the Watch screen firmly for additional functions, like switching to a heating or cooling mode, setting the away status, or turning the fan on and off.
While the app's minimalist looks betray the simplicity of its operation, what they don't show is the amount of planning, design, development and refinement that went into it, ensuring it becomes something that is enjoyable to use and experience.
The goal was to make a product hat would not look out of place next to one of the apps bundled with the Apple Watch.
Please note also that this app can't work with Thermostat E with Heatlink, sold in Europe.
