I have 3 yeelights in my living room. They are in a group called living room lights and can be turned on/off with the harmony remote. (press on/ longpress off).
The remote has + and - brightness buttons on it.
I have attached these to the group. The problem is that it does not work.
When the + brightness is pressed, it will only affect one of the 3 lights in the group. It will then appear to break if you go to max brightness and then continue to press the button. This causes the whole group to become unavailable in HA for a few minutes.
The - button does not seem to have any affect on the group.
I agree. It sometimes works as expected, but only to a point.
Like i mentioned in the original post, if it works, something will happen causing the lights to become unavailable or only one in the group will be affected.
