How can I detect a not working device ?

When I disconnect my INNR SP220, I cannot see a 'dead' sign anywhere on the dashboard.
So there is not keep-alive communication in idle?
When I sent a command to the SP220 the timeout counter is starting to increase. Is this my only way of seeing that something is wrong?

There are somes scripts in the wiki : https://github.com/pipiche38/Domoticz-Z ... md#scripts

If you are using zigbee2mqtt then you can look here: https://www.zigbee2mqtt.io/information/ ... ation.html
In particular availability_timeout

What is the problem you want to solve ?

Its not possible to detect immediately a "disconnected" device, because the device can't send a message to say it is disconnected.
The only way to do that is monitoring the delay with the last time the device have send a request, but this don't work at the second. Some solution can check for device response and mark it as disconnected if there is a timeout, but you need to send a request for that.

And on zigbee, you need to never disconnect yours devices.

What you can do is sending report very minute from the device you want to check, and check every minute in Domoticz if you got some update.

If device is powered, you may decrease the interval to few seconds, but load will increase...

For me , I think the 1st question is what is the problem you want to solve, then we can think about solutions

I don't there is a problem anymore, as @ensingg does not respond.

I must be sure that a switch is working.
As an administrator i like to monitor as best as in can.
I think for now I know enought.
Made a scheduled script that check via rest api.
Thanks

If you want to be really be sure if a switch is On or Off, you can check the power usage with a wattmeter.
