I’ve just added the Conbee II stick to HA using the Hass.io plugin, all working well and I’ve successfully got a Xiaomi/Aqara multi-sensor confirgured and reporting states to HA.
Only thing I’m having trouble with so far is the built-in daylight sensor. It’s reporting to HA as unknown and is ‘unreachable’ in the deConz web console.
Is there an extra bit of config needed? The timezone is set correctly.
