Apple Watch, Nest Thermostat, and Siri. Together at last.
＊ The app has Siri Voice shortcuts for seamless Siri control of your Nest, from the iPhone, Watch, iPad, 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. It lets you see your thermostat info on the Watch complications, and control it using the iOS widget.
_____________
• Using Siri voice shortcuts you can control many aspects of your Nest, such as instant activation of heating or cooling, setting the temperature by saying how many degrees you want to set, increasing/decreasing the temperature, and setting the Home/Away state. Thanks to Thermo Watch, It's all finally just one casual "Hey Siri" away, all with informative visual and verbal feedback.
• 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 see the thermostat info on the home screen widget, you can swipe to the widget panel to adjust the temperature on the interactive 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 is fully functional with an initial purchase. The in-app purchases are used only for giving a tip to the developer.
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".

Set Geofence around your home to reliably set the Home and Away state when you come and go.
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, choosing the active temperature sensor, 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.
Thermo Watch does not collect any of your data. Your login information, thermostat settings, and any activity - all of it flows exclusively between your devices and Nest. Author of Thermo Watch does not receive any of it, at any point.

What's New in Thermo Watch for Nest & Ecobee
15.8
May 18, 2022
＊ iOS Home Screen widget now has interactive controls on the Mid, and Large sized Widget: Start/Stop Heating/Cooling are now available with one button press on the widget.
＊ Full screen support for the Series 7 watches.
＊ Siri Shortcuts on the watch should no longer repeatedly ask to Allow shortcut to run actions. Shortcuts on the watch work best when the watch is on its own on LTE, or when the phone is nearby to provide good network speed.
＊ Watch complications should now update correctly, and they are tied to iOS Home Screen Widget updates. Please make sure to have Thermo Watch Home Screen Widget enabled on your phone if you wish to have watch complications update in the background.
＊ In the iOS app settings, you can set the Low Temperature Warning. This feature requires Thermo Watch Home Screen Widget to be enabled on your phone. With this enabled, the app will send you a notification when the home temperature drops below specified threshold. Useful if you have a furnace that works unreliably, and reports that it's heating, when it's in fact not.
＊ The app can now detect if the thermostat is in Temperature Holding state, and offer to end the hold so that you can change the temperature.
＊ Fix for the app not always correctly switching from Off mode to Heat for some users. Thanks to Will who reported this!
If Thermo Watch has changed your home experience for the better, please consider giving a small tip using the Tip Jar option from the app's menu.
Love the app but recent update took Temp Adjust buttons away from widgets
Great app, and to be honest a real shame that Nest & Apple couldn’t have done this themselves, so grateful to the Dev for making this. But recent iOS 18 update took away the up/down buttons on the iOS widgets. The only way to adjust temp now is actually opening the app. I like being able to finely tune the temp from the widgets while on the Lock Screen. It makes no sense to have a widget whose sole purpose is to open an app. I want to adjust the device directly on the shortcuts/widget screen.

Response from developer
Hey Nathan, no worries, the app still has the old interactive widget available. If it disappeared from where you previously had it, try just restarting your phone, and it will likely reappear.
The app now has two types of widgets:
- There is a new type that can be placed anywhere on the home screen, but which does not allow interactive control of the thermostat. This is the widget you are seeing now, because iOS sometimes replaces the old widget with a new one when the app is updated.
- There is an older style widget, which you’ve used all along, that can only be added to the widget panel of the iPhone, but which allows interactive control of the thermostats. To add this widget back, swipe to a widget pane, then scroll down and press Edit at the bottom. Then scroll down again, press Customize, and choose Thermo Watch from the list of old style widgets. Again, if you don’t see the Thermo Watch on this list of old style widgets, just restart your phone, and it will re-appear on the list.
You can keep both widgets active - you can for example place the new one somewhere on the Home Screen and it will update periodically to show your thermostat status. At the same time you can keep the one you always used on the widget panel.
