@balloob @bramkragten should we expose the device area id per entity as well or should that be a frontend thing?

[balloob]

🎉 Looking good.

@bramkragten do you think that this is good to go? We can always extend APIs later if we need to.

[bramkragten]

Yes, I think this will work

[MartinHjelmare]

We should avoid using the word entity for entity entries in the entity registry.

[balloob]

Can be merged once Martin's comments addressed! 🎉

If I request the state of an entity, the API didn't exposed the area id.

The Entity registry is not part of the state machine.
