Battery powered dead node status

[Gis70]

Hi, I wonder if the way to determine battery powered nodes status is working as expected.

For example, I made a script to ping node every day and then check theirs status.

I had battery powered devices which didn't responde since 5 days (wake up setted every 24 hours) and the node status after a ping is : node asleep.

What is the algorythm ?

Can't we base the algorythm calculating if wake up delay is overtaken for battery powered devices and then mark them dead ?

Thank you for you help to make my system more reliable.

That only works for listening nodes, not sleeping ones. Those only wake up for a very short time, send their wakeup messages and then sleep for the rest of the wakeup cycle.

Right now the logic in the driver considers asleep and dead to be states without a transition between them, meaning a sleeping device will never be considered dead.
You could use that approach to detect problematic nodes though. But consider that there might be delays in communication, one-time connectivity issues, etc. If you're too strict, you might end up with false positives.
