Hi, thanks for trying to help.
My system is already open for access, please see over here:
I’ve left the device “Lampe Pelletkeller” in this limbo state so you have something to look at. This device actually did go offline briefly; LEDVANCE Tuya app redetected it online instantly and operates it just fine; SmartThings just refuses to pick up that it’s back. The brief offline event has been many days ago, so I don’t have an exact timestamp, but I do have that “device is definitely online and working, but SmartThings thinks it is offline” state of affairs.
Thanks for your review and suggestions. Whenever I see another device go not-really-offline, I’ll come back here and add info.
best regards,
Peter
