Hello. Automations are mostly triggered by state changes. But what about the case that state does not change for some time? The sensor sends heartbeat and what if the heartbeat does not come? How to start the automation please?
I think about this scenario - start automation when sensor sends value, then wait for 10 minutes and then start automation script. Every new state change would retrigger the automation, so if sensor changes state in less than 10 minutes, the action is never ran.
This has a disadvantage - when the sensor state never changes, the automation is never run. So there must be a better way…
