Inactivity
Inactivity triggers when the network has not detected a tag for a specified duration. It uses the asset's Last detected time, so any data from the tag counts: a position, a sensor reading, or a sighting by a hotspot. A tag that is detected but gets no new position does not trigger it.
How it works
If the time since Last detected exceeds the threshold, the rule triggers. This catches tags that have gone offline, lost power, or moved out of hotspot range. The alert resolves by itself when the network detects the tag again. You can add the rule from the Last Detected box at the top of an asset's page.
The alert gives the tag's last position, and the registered device that reported it: "Cage 42 inactive for more than 24 hours, last position in Customer Site X, from Bob's TC52". When the tag was outside every zone, the alert gives the coordinates instead: "last position at 52.19570, 0.16900". The place and the name reach every channel (dashboard, email, Slack, webhook), so the reader knows where to look and whose device to start with, without opening the asset.
Skip zones where a tag may go quiet
Some places are allowed to swallow a tag for a while: a customer site that keeps roll cages for days, or a store room with no coverage. Add those zones' keywords under Skip assets whose last position is in a zone with these keywords. A tag whose last position is in a zone that carries one of the keywords does not alert.
