HI @DwayneMccoy, poll can be empty, if you have sonos use refresh but set 8hr, sonos use the refresh for subscribe if you set a tiny time you going to make a lot of subscriptions and your system going to collaps, then use 480 min and select some of your devices, watchdog use timers too, but use the events to back up the timers, just select some devices like temp or power or motion detector.
