I never had or noticed this issue until three days ago (03/26/19), while on current 15.5 firmware, my louvers started doing this actuation every 6-30 seconds. I've started the wheels for a Ranger visit request, after he calls me sometime after the 3/30/19-3/31/19 weekend....
Any hints or ideas what's going on, or more importantly, what the fix is, while I wait (and listen to my louvers "snore" in my garage)??
