You can manage all your tado° X room control devices (Smart Thermostat X, Smart Radiator Thermostat X, or Wireless Temperature Sensor X) in the Amazon Alexa app and with Alexa voice commands.
To control tado° X devices with Alexa, you’ll need:
a Matter-compatible Alexa controller (i.e. certain models of Echo and eero)
You will need to add your tado° X room control devices one by one to the Alexa app, but you don’t need to add any tado° Thread border routers (e.g. Bridge X, Heat Pump Optimizer X, Wireless Receiver X).
To make sure that your voice commands are properly understood, we recommend that you group devices in rooms in the same way in the Alexa app as in the tado° app.
Adding tado° X devices to Alexa
You can add your tado° X devices to Alexa either from the tado° app or the Alexa app. You will need to add them individually. First, make sure that:
the device that you want to add is powered
your phone is running on iOS 16.4, Android 9, or later
In the tado° app (recommended):
Open the tado° app.
Select Settings > Rooms and devices and select the device that you want to add.
Scroll down and select Device linking.
On iOS, copy the setup code when prompted and proceed to the Alexa app to add the device. Paste the code when prompted.
On Android, select the Alexa icon and follow the pop-up instructions to link your device.
Repeat for each device.
Alternatively, you can add the device from the Alexa app. Note that this method only applies to brand new devices (not yet added to the tado° app), or devices that have just undergone a Factory Reset. Otherwise, link your device as described above.
In the Alexa app:
Alternatively, you can start by adding the device from the Alexa app, but there are a few limitations to be aware of.
First, we don’t recommend setting up your tado° devices only in the Alexa app. This is because Amazon has not yet implemented NAT64 in its Thread border routers, so they can’t process important tado° firmware and security updates. This is why you need a compatible Thread border router in addition to your Alexa Matter controller to properly connect your tado° devices.
Note that this method only applies to brand new devices (not yet added to the tado° app), or devices that have just undergone a Factory Reset. As with all smart home platforms, you can only identify a device via its Matter QR code if the device has not yet connected to a Matter network. Also, the device discovery function that the Alexa app suggests when you search for tado° in the Alexa app won’t work for tado° X devices.
Open the Alexa app and select Devices.
Tap on the + icon > select Add Device > scroll to the bottom of the list and select Other > select Matter.
Select Try numeric code instead and select Enter code.
Enter the numeric code from the tado° app. To access this code, open the tado° app, go to Settings > Rooms & Devices and select Device linking for each device.

For more information about using Alexa with your tado° devices, please refer to Amazon’s official support pages:
general information about Alexa smart home connectivity
how Alexa works with Matter-enabled devices
how to set up and use Alexa voice controls
Adding your tado° X device to multiple third-party Matter fabrics (e.g. Apple Home, Amazon Alexa, Google Home) can slightly decrease the device’s battery life because each fabric requires the device to send and receive additional information.
Most users manage their tado° X devices in the tado° app or with one other smart home platform of their choice without experiencing a significant effect on battery life.
