I'll look at the logs when I get home - too hard on the phone
But one thing I wanted to point out is that on dimmer sync the master NEVER follows the slaves. If you move the slaves, or turn them off, the master does nothing. It is a true master/slave relationship.
There are other apps where it is bi-directional, but not on dimmer sync.
I figured the master was able to follow the slave because it was moving when I was moving the salve but I did some testing and it was just a coincidence, the master "hunts" about 10 seconds after I moved it. There seems to be an error with "IndicatorNever" what ever that is.
