Sensor – Last Seen

Last Seen

Also, on the status page for your sensor, you will see ‘last seen’. If you hover your pointer over the information which displays the time it was last seen ( 3 hours, 26 ) you will be able to see more details about the date and time.

‘Last seen’ means the last time that any valid message from the sensor was received.

There is a heartbeat transmission every four hours even if the Status doesn’t change. If the Last seen is more than four hours you should check your trap because something isn’t working (this could be the gateway or the sensor).
