Ha, ha, ha…we went by process of elimination. First we confirmed that the zwave mesh was ok, next came community apps @Mike_Maxwell s Keenct survived because I was firm it wasnt polling any devices… , then we looked as Smart Lighting and by that time we were both tired and just about to give up when I noticed that all of my zwave switches reported activity at the same time. So that was that. The support received was exemplary and didn’t talk down on community apps, they were just first in line up for elimination when troubleshooting.
