I have a Z-Wave device which is turned off for 2 weeks now but in OpenHAB it still shows online. I have tried to Heal device also on controller select Synchronize network. Whole OpenHAB gateway was during these 2 weeks at least 2 times rebooted, but device still shows online…
Device is NEO COOLCAM NAS-WR01ZE power outlet which should be always on, so
I would assume status is updated easily…
