## What is Thermo Watch for Nest & Ecobee?

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 5G/LTE, and can work when the iPhone is not around - as long as the watch itself has internet access (either 5G/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 start/stop heating or cooling directly from the middle and large size widgets, 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 the initial purchase. In-app purchases are available only for tipping 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".

Visit https://thermowatch.net/siri website for the detailed instructions of Siri operation.

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 and hold the Watch screen for additional functions, like switching to a heating or cooling mode, setting the away status, seeing the temperature sensors, 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.
This app and its developer are unaffiliated with Google Inc. or Google Nest. Nest is a trademark of Google Inc.

### 5/5 — Good Developer

*2026-06-30, version 15.9*

Developer really wants his app to have a great success and will message you if you have great ideas

### 5/5 — Exactly what I needed

*2026-06-18, version 15.9*

I have an elaborate smart home and I use Home Assistant as my main hub. While there are ways to make HA work with my watch, it’s very convoluted.  This was simple and easy and I was up and running in a few minutes.  As a bonus this app doesn’t collect any day at all.  Well worth the $3 cost for this app. It’s only been a day, but it’s a great app purchase so far. With a single tap of my watch, I can control the temperature.  Not sure what more you could ask for.

### 5/5 — Much better than Nest app

*2026-03-24, version 15.9*

Now if he Mark would just write an app for my Honeywell thermostat.

### 5/5 — Works w nest 2020 thermostat

*2026-01-15, version 15.9*

Love this ! Made my nest 2020 display removing humidity on my phone and Apple Watch so I can better control my temps and humidity. Thank you!

### 5/5 — Works great!

*2026-01-14, version 15.9*

This app connected right away and works perfectly with my Ultra 3 watch and my Nest Gen 4. I’m able to control my thermostat right from my watch. The feedback response is great. Simplistic and works great!

### 2/5 — Random behavior

*2026-01-07, version 15.9*

I set up the short cuts but Siri still will only work if the app is open, defeating the whole purpose of having the app. It also has been building a schedule with temps I never set it to. There is no trial period and it doesn’t work…

### 5/5 — Still Works!!

*2025-11-11, version 15.9*

Google killed Nest but somehow I can still control mine using this app! Brilliant!

### 5/5 — Much better than Nest app

*2025-09-05, version 15.9*

First screen gives you all the info unlike Nest app. Hoping it still supports my Gen 2 thermostats after Nest/Google pull support in October.

### 3/5 — Recent update breaks complication update

*2025-08-14, version 15.9*

The watch complication no longer updates unless you tap the complication to open the app on the watch. I have my refresh set to 15 minutes and two hours later it still doesn’t update unless you open the app.

### 5/5 — Nest gen 4

*2025-07-13*

Works well, looks way better than Google home and top notch service from Marko!👍🏻
