Using Matter to Connect Nest Thermostat with HomeKit

Cupertino, August 10, 2023

Matter has made strides in unifying the smart home with one standard, and Google is now updating its Nest Thermostat to support Matter and connect to Apple HomeKit. However, only the 2020 Nest Thermostat is currently compatible with Matter and HomeKit, although Google might update the Nest Learning Thermostat in the future. Another option to use Nest devices with HomeKit is the Starling Home Hub, which works with more Nest Thermostat models.

To connect a 2020 Nest Thermostat to HomeKit using Matter, you'll need an Android device, as the Google Home app only supports Matter settings on Android currently. Make sure your Nest Thermostat is updated with Matter support, although the update might not have reached all users yet. In the Google Home app on Android, open the device settings for your thermostat and tap "Linked Matter Apps and Services." Then tap "Link apps and services" to connect the thermostat to other Matter-supported apps or use a QR code to link it to other apps. Generate a QR code and switch to your iOS device.

In the Apple Home app on iOS 16.4 or later, tap the "+" button and select "Add Accessory." Your device will search for a QR code, which you can use from your Android phone to pair the Nest Thermostat. Afterward, you can use the Nest Thermostat with other HomeKit devices. Note that you'll still need a hub compatible with HomeKit in your home. It's likely that this process will change once the Google Home app on iOS supports Matter, but for now, it's a significant development for native Apple Home integration with the Nest Thermostat.

If you're interested in using a Nest Thermostat with Apple Home, you can purchase a new thermostat for $129 or find refurbished units at a lower price. Keep in mind that affiliate links may generate revenue.
