You need to make a rest sensor.

Thanks a lot for the tip.
And which node should I use to check in Node-RED?

Like any other sensor. You could use it in a events current state node. It will output when the sensor changes. Connect to call service node and define the action.

For anyone stumbling across this like me:
Nowadays there is a binary sensor which can tell you if an addon is running. You just have to enable it.
Go to Settings > Devices > Addon in question > Sensors > Running > Advanced Options > Enable.

Using the not_running trigger you can trigger on an addon stopping.
