My OpenHABianPi has ethernet WIFI connection and is placed in my summerhouse 150 Mi away.
I’ve been running lights/door sensors/temp sensors remotely since last spring.
The device has two times during this period gone offline for about two weeks, before it decides to go online again. I haven’t done anything to correct the problem; it has corrected itself.
The WIFI connection works fine (my Arlo Cams work perfectly).
Anyone feels to have a shot at it?
