This morning I woke up with the alarm sounding, because the zigbee button that was used to disable it did not work.
According to the logs, the device wasn't reporting to the Hubitat since a few days. Apparently the battery died with the last reported value at 46%. The button also used to report temperature every hour.
Is there a way to get a warning if the button does not report in?
I competely agree with @bjcowles has said.
I use it and here is a screenshot of the tile.
I have a rule that turns on and off the switch that looks for inactivity every 5 minutes.
