Matter codes are laser-etched on each tado° X room control device. Each Smart Radiator Thermostat X, Smart Thermostat X, and Wireless Temperature Sensor X has its own unique Matter code. You can scan the QR code or type in the numerical code to add your device to the tado° app or any other Smart Home app that supports Matter.
Note: Only on the initial installation of the tado° devices, you scan the QR Code on the tado° device. If you want to add the same device to a second Matter app, you need to follow these steps:
Open the tado° app.
Go to Settings > Rooms and Devices.
Select Matter device linking for each device.
On the Smart Radiator Thermostat X
For Smart Radiator Thermostat X, you can view the registration details in the following two ways:
1. If you switch on the display by rotating the dial, you will get registration details displayed. In case you activate for the first time, you need to select the language and screen orientation previously. You can always return to the initial state by factory resetting the device.
Please note: This information is only displayed if the device has not yet been commissioned to a thread network.
2. Remove the battery pack from the base of your Smart Radiator Thermostat X to find the registration details on the underside of the device.
On the Smart Thermostat X or Wireless Temperature Sensor X
The Matter code is on the back of the device. Remove the body of the device from its backplate by gripping the outside of the device with your hand and gently pulling it away from the wall, just like you would when replacing the batteries.
Please note: the tado° Bridge X, Heat Pump Optimizer X, and Wireless Receiver X don't have Matter codes. They are essential for enabling communication between your tado° X devices and any compatible Smart Home apps, but you don’t need to add them to Matter apps.
