There seems to be a light on that Hub that is missing properties that are required. Could be a bug in the Matter bridghe implementation of the Aqara Hub, or just a device specific fluke. The light reports itself as a light that supports color temperature control while in reality it doesn't. At least that is where the error points at.

Remove the light (do you have any idea which one it can be?) from the Hub and try to pair it again.

Aqara Hub M1S has RGB light built-in :(

[marcelveldt]

shoot haha, in that case we're out of luck for a workaround. We'll have to wait for Aqara to fix the underlying issue then. Is it mandatory to bind that RGB led to the HUB? If I remember correctly, for the m2 Hub you can choose what devices to bridge

Is it mandatory to bind that RGB led to the HUB?

That led is bound automatically and I have no additional control on it. So let's wait. Of course beta is beta only... (btw my M2 hub works fine!)

thanks anyway!
