I added my Hue dimmer to the Home app and boy do I regret it. You lose that ability as far as I can tell. Yes, you can assign each button to a scene, but I liked it the way it was. I was hoping to get similar functional but ALSO being able to add in control of a Caseta switch.
Now I have one scene with "On" that does include Caseta, but not multiple scenes with subsequent presses.
You can use the accessory to trigger both a homekit scene and still use the philips bridge for multiple settings.
However if you have multiple settings on the home app which is what I'm trying to do it looks dark.
This works:
Click 1) Hue Scene 1, Home Scenario 1
Click 2) Hue Scene 2, Home Scenario 1
...
This is what I'm trying to do:
Click 1) Home Scenario 1 (Lamp Settings 1 (hue), Spotify list 1 (home), Speaker x,y enabled (home))
Click 2) Home Scenario 2 (Lamp Settings 2 (hue), Spotify list 2 (home), Speaker x,y enabled (home))
...
Right now I just bought another hue dimmer which is dedicated to home which gave me 4 different mode settings.
I might move everything to applescript and make the logic in there instead (enabling unlimited clicks)
