Sonoff 4ch pro problem

I installed sonoff 4ch pro to control an irrigation system at home, that works with four 24v AC - solenoid valves. So this way I can set the timer for this system and control it by wifi. I followed the instructions and set it to self locking mode, and at the beginning it was working properly. But the problem is that there is one channel that selfs activate all the time, so I had to disconnect that relay otherwise my garden was flooded!!!! I need the four channels working properly, what can I do to solve this problem??

I gadget the dame problem above with my sonoff 4ch pro R2. The Channel 4 turn On randomly. I nave no remote controller, Onlus the app on my phone Please any suggestioni Is usefull!!
I have the same issue. Funny thing with device is that it auto pairs with any nearby 433mhz remote signal. In my case it was the security alarm movement sensor. If you don't have any 433 movement sensor or remote then it might be from neighbours. Now the way to resolve the issue for the time being is that you have to pair a 433 remote with it or to wipe off RF remote settings by long press s5 inside the body. Hope that helps. Cheers.

I have a sonoff 4ch pro that activates on its own, can someone help me solve the problem?

I have exactly the same problem  with 2 devices 4ch pro R3

Channel 1 is continuously on and off on device 1 and channel 1 and 3 are  continuously on and off on device 2 . Each device  has a life of its own.

The log shows that it is turned on and off randomly by the device.

On the 4ch pro R3 is no S5 button to clear.
Thanks for helping me out here.

My sonoff 4ch pro r2 works for few hits and stops. This happens with all 4 channels either pressed or by remote. Tried to connect to Wi-Fi with no success. Tried everything such as disabling Wi-Fi security. This is the second device I have. The other one simply stopped completely.
