I contacted support and they suggested restarting the device in the settings and if that doesn’t correct it, then remove the camera/device and go through the setup process again. (This is what I did to make sure it was all set). Be sure to download any footage you need prior though.
After doing that, the last night it hasn’t turned itself back on so that’s a good sign.
Still very odd and still no idea why it is that happened, but it at least seems to have been “fixed” by removing and re-adding the device.
Still happening. Witnessed my camera that I had completely turned off (Eufy 2K Pan & Tilt) rotate down and around, then back up to its off position. It had a blue led during this. I immediately checked the Eufy Security app, and the camera was in fact still off. I checked the System updated information and it says the last update installed was on 1/27. Someone from Eufy needs to explain why this is occurring to all of our cameras. I’m about to return the two I own if this doesn’t get resolved or have a logical explanation why a camera completely turned off is turning on in the middle of the night, rotating with a blue LED and then back to the off position all on its own and no firmware or system update information listed in the app for that device.
