Thanks for the response - being installed in the next few days so will give it a go!
I’ve actually just got around to this.
Connected all 4 inputs to a switch - but only IN1 is switching (red)
Each input individually seems to work if only that is connected but not if all
I found something on another forum that seemed to indicate that Parameter 14 needs to be set to brightness mode for this to work, but I can’t work out how to do this in Homey
I also don’t know that this will work so any other suggestions welcome!
Edit: Value for parameter 14 is apparently 8738 based on post here: http://forum.micasaverde.com/index.php?topic=123955.0
Edit2: I wonder is this just 14,2,8738 in the parameter field? If so, before I do (as need to rewire) would be good to know if this will revert settings that were on before
