Additional information

This seems to be because Z2M is publishing state attribute as null until it knows a state, so it's None in home assistant.

I'm not quite sure how to get around this honestly. It's not like an assumption can be made of the default state of an enum expose, and None shouldn't be specified as a valid value because then it'll appear in a dropdown.

Well at this point, it defined possible values and next set a value that isn't possible according to the list provided by z2m... 🤷

Hmm... actually, this might be a bug in the MQTT select entity @ Home Assistant...

Setting a None (== STATE_UNKNOWN) is actually valid for an integration to do, however, should not be accepted as user input from a service call @ Home Assistant.

Fixed upstream!
