Another firmware and again after few days radiator (in zigbee mode) is disconnecting, now in app there is network error when we go to temperature graph and of course warning about temperature difference.
Hub M3 with latest firmware, W600 and aqara app also. It shouldn’t be problem with network stability because device is about 1 m from hub.
Update:
I restarted the Hub and control of the W600 was restored. The radiator did not start automatically, but changing the setpoint manually brought it back to life.
