State stalled - detect with node red

[sender]

Hi,

for my entity sensor.power_consumption_total I want to detect “stalled” state. Thus normally this state changes every 1-3 seconds but sometimes my integration hangs for a while (minutes-hours). I want to detect that via node-red and reload the integration (then it is solved).

But I can’t get my head around a feasible way to detect/to do.

Use a trigger-state node, RBE, compare… but how ?

any hint or example?

Have an inject node to current state node of the sensor.

Then a switch node if msg.payload == flow.previous.
And one output of otherwise.

After the switch if payload == previous perform the reload.

Otherwise change node flow.previous = msg.payload

Now set the inject to repeat however often you think is reasonable (every three seconds or five seconds).

I’ll set an event state to the entity and leave the rest blank. Then use a trigger node set like so. As long as there is updates to the sensor it will reset the timer. If it doesn’t it fires a message that I send to a notify call service.
