Sonoff CH4 PRO R3 switching randomly

[PiotrLesiak]

I got 6 Sonoff CH4 Pro R3 devices, I use them to control my window shutters. One of them (only one) is randomly switching channel 4. I checked logs and there are multiple records like this

2023-09-25 19:38:57 [D] SysInfo: {'installation_type': 'Home Assistant Core', 'version': '2023.1.1', 'dev': False, 'hassio': False, 'virtualenv': True, 'python_version': '3.9.2', 'docker': False, 'arch': 'aarch64', 'timezone': 'Europe/Warsaw', 'os_name': 'Linux', 'os_version': '6.1.21-v8+', 'user': 'homeassistant', 'sonoff_version': '3.5.2 (2ad1cd7)'}

Only difference between them is that faulty one has firmware v 3.7.6 and the others has v3.7.3

Logs in Ewelink app for that device also shows that action was triggered by ewelink account. That happens quite randomly, sometimes it happens every couple minutes and sometimes it doesn't happen for hours.

Any idea what can be reason for that odd behaviour?

There is can't be any magic. Or you have some auto somewhere. Or you setup this auto on device. Try to reset it and setup again.

[PiotrLesiak]

I reset and setup device again, unfortunatelly got same effect. I don't have any automations in ewelink app. Guess I'll return that device and get another one in that place.

Edit: I sent message to sonoff support. I'll post their response here for people with same problem.

@PiotrLesiak I have the same issues. Did you manage to solve this?

[PiotrLesiak]

Unfortunately not, I returned my device to seller and they gave me new one.
