Did you make progress?
I have set up my one PIR with lights and have the lights come on at 50% based on sunset time +/- and off at sunrise +/-.
If PIR is active lights go to 100% and when PIR goes off I set lights back to a configured %.
The only issue I have is the lights have to be told to go back to % setting I had them on at, I can't get them to actually remember that they were at 50% before.
