RM help needed - ZooZ MultiRelay Zen16 "Last Activity At"

I said this the other day.
Bear in mind, I'm no genius.

Also, the ZEN16 can do auto on/off. You could set it up so that an unused relay, or just a signal I think in the ones, goes on and off periodically, and test for duration. Probably wouldn't want to do the relay, but I think the new 16's can be parameter'ed to just signal.
