The following script is always running but executes given commands only once after iobroker restarted (either via ‘iobroker restart’-command or via a system’s reboot). It does not need any additional objects etc. In this special case it checks in intervals if the Zigbee adapter is running, then restarts the adapter once (because of an issue that’s not part of this post). Please keep in mind: The script also executes every time it is saved.
/*
To run once after iob start / restart / system reboot.
By using an interval with a simple logic
the script can run infinetely but only executes the given actions once.
