I have a big Problem with my shellys.
I don’t find any log, error or something.
Every night and not on a fixed time (there is no rule or script or something else running) all shellys
are switching to “ON”.
My Garage door is open, my heat pump starts,…it is really horrible…
The event.log does not show anything? Then this might not even be related to OH. Do you use the Shelly cloud? I have one Shelly Dimmer 2 that switches itself on or off sometimes when the wifi gets disabled. I could never figure out why but the Shelly support couldn’t help me either… however I only have one device that behaves like that and it is clearly related to a change in wifi availability. I never experienced this in other situations.
Just a few other ideas:
Can your openHAB instance be reached from the Internet? If so, is there a proper authentication mechanism in place? Could there be someone having fun with your devices at night?
What do you use as default behaviour after a power loss for your shellies? ON? May a power outage be the source of your problems?
