I have a lot of Sonoff devices including 5 Sonoff 4CH Pro, and with one of them I have a serious problem.
After pairing with RF-remote it works for 2-3 days, and then channels 2 and 4 start automatically. I tried to reset it with the s5 button, but always after 2-3 days it stops working, and channels 2 and 4 are started automatically.
This is frustrating when at 2am or 1pm when is very bright, light turns on.
Any idea to solve the problem?
