Device Health
How often each sensor is expected to report. A sensor that goes quiet for longer is flagged late, stale, then silent.
Set intervals from observed behaviour, not assumptions. The observed median column below shows how often each sensor actually reported over the last 7 days — use it to check the expected interval is realistic. Late = past the interval; stale = past interval × grace; silent = nothing for over 24 hours. A sensor that has never reported is unknown and never raises an alert.
