Did it with "Follow up with piston xxx" and it seems to work. But now, after leaving run overnight, it locked up the lights (Sylvania Lightify GardenSpot RGB lights) and some of my other zigbee lights were stuck on, in the morning. I think it "crashed" the zigbee network with so many requests. Lol Time to slow down the flashing and color changing I guess. I had it alternate every 3 seconds, which I didn't think was TOO bad.
