What kind of devices do you have ? Any non certified devices as well perhaps ?

[jaysus82]

I have lots of Hue devices and several knx devices connected to a 1home server which is a matter device. All the devices still work via Google home or the smartthings app. So I think it's not a matter / 1home server problem.

[marcelveldt]

That it works via Google or Samsung doesn't mean anything. Home Assistant is most ahead of the game regarding Matter/device support so any compatibility issues will reveal itself in an early stage in HA.

So for example the KeyError that is causing the crash in your case; the device sends a spec incompliant value.
We will have to add a patch for that and maybe also ping the device vendor to fix their firmware because 255 is not a valid value for clusters.OnOff.Attributes.StartUpOnOff

[jaysus82]

Can I somehow identify which device is causing the error? Maybe I can then deactivate that temporarily as a workaround?

[kmohamad]

I have the same error and I also use the 1Home server. Pretty good chance that's what causing it.

[jaysus82]

Nice, thanks for the info. Hope they can fix it.
