Notes
Pairing
To pair this device you have to install the device via its installation code. The installation code can be obtained by scanning the QR-code on the inside of the battery cover with your smartphone. Then put the device into pairing mode, by reseating a battery. The device is in pairing mode, when the display shows ">o<". Don't press the button on the valve, before pairing is completed. In zigbee2mqtt navigate to "Settings" --> "Tools" and click on "Add install code". Paste the code you got from the QR-code and confirm by clicking "OK" which will get zigbee2mqtt into pairing mode automatically. Wait for your device to be joined. The valve should still show ">o<" on its display. Now you can press the button on the valve to initiate valve adaption. If you have variant with Matter (Smart radiator thermostat II [+M]), QR code is for Matter only. You can construct Install code from the IEEE Address and Install code (it is next to QR code): Bosch prefix (40 characters), IEEE Address (16), DLK, Install code (36). Example of Install code: RB01SG0D83101826480080000000000000000000XXXXXXXXXXXXXXXXDLKXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Factory resetting
To factory reset the device remove one of the batteries. While pressing and holding the device's main button on the front, insert the battery back. As soon as the device's LED is starting to blink orange while showing "RES", release the main button and press and hold it again until the device's LED is lighting up green. The device will then restart into the calibration process and look for a Zigbee network to join. In case something went wrong, the device's LED will start to blink red. The process has then to be start all over again.
Using the manufacturer specific operation mode
The system_mode
exposed by the device according to zigbee specification is always 'heat'. To set or read the actual operation mode of the device, use the manufacturer-specific feature 'operating mode' (see below)
OTA updates
This device supports OTA updates, for more information see OTA updates.
