Make Areas usable in Node-Red

[andrewschmidgit]

The Problem

I am trying to create a generic Node-RED flow for my TVs. If any tv is paused in the house (and it's nighttime but that's not important) I want the lights in that room to turn on. Then when it's resumed, turn the lights off.

I need the ability to get the area_id from the state of an entity, and then query entities based off of that area_id.

Another example would be when casting music to any speaker in any area to group-cast to all speakers in that area.

The Benefit

I would be able to write a single flow in Node-RED that would work for any area in my house
