Zigbee Pçermitt Error Unknown with Bosch device

Hi All,

Hopefully you can help me. I’m trying to add a Bosch radiator thermost 2 to HA via Zigbee with a Conbee 3 dongle. I’ve seen that Zigbee should support also Bosch Devices as well via QR code.

To add the device I’m utilizing the action ZHA.permitt but when I lunch it returns the fan unknown error. Any idea on what I could try? Many thanks!
Below the log:

Actually now with the same action and addresses I’m getting a new error:

zigpy_deconz.exception.CommandError: <CommandId.write_parameter: 11>, status: <Status.UNSUPPORTED: 4>

Maybe I’m doing something wrong??
