So, the question is how to tidy the app?
I formed a group of all four channels so I have achieved the main aim of all four outputs controlled with one slider.
My problem is that the App shows both the separate devices and the group together with a “wheel” for different temperatures.
I want to keep it simple for visiting guests. All I want them to see is the picture with an on/off switch and a volume slider.
Is this possible?
Furthermore, after more experimentation, it is possible to break the app if you select “colour” . The LED flashes and then goes off needing a rebuild on the app. Not good for visitors or other family members.
Also, Alexa does not respond to the Group name for voice activation. It needs the channel number as well.... so, four channels need turning one at a time....
Is there another way?
