Is this ever going to be a thing? Unless room support is added, using Hue B Smart smartapp (Which does support rooms/groups of lights) is realistically the easiest way to control a home with boatloads of hue lights, which kind of sucks because it’s not going to run locally.
There’s a big responsiveness difference when telling Alexa to turn off the room named “Everything”, than having her turn off a group defined within alexa named everything. The first will turn off all lights at the same time within 1-2~ seconds, the 2nd will turn off lights one at a time until they are all turned off, which can take up to 10 seconds with enough lights.
https://developers.meethue.com/documentation/core-concepts - It’s all part of hue’s api. This would also mean rather than having a list of 40+ lights, I would only have a list of 4-6 light rooms.
