$location property.

Thoughts on adding a $location device property? This would prevent having to overload the $name field with location info and possibly make searching easier.. or does this belong 'outside' of homie?

Well, device properties are properties that are actually related to the device itself, not it's environment. A location depends of the environment. You will tell me that on the convention, the example for the $name property is Bedroom temperature sensor, but after consideration, this is not "idiomatic" Homie, so I'll update this to Temperature sensor.

So yes, I think this is the role of the controller to know and manage the location of each device.
