matterbridge-home-assistant start without errors and register the light but the exception is thrown as soon as the light goes off

It appears the addon can't handle null attributes like brightness when devices goes off.

I have seen a similar behavior with the colors, but no of my lights populate a null brightness when turned off. For me the brightness stays at its level but the state changes to „off“. even in home assistant i can still see the brightness level after turning The light off.

But okay - another edge case to do 😁

I'm seeing loads of entries in the materbridge logs as well while the lights are off.

Could you give it a try with version 0.5.2 ?

So far so good.

Tested with Yeelight Color2 bulbs and a WLED led stripe.

Thanks.
