I have exactly the same problem as you with a 4ch pro.
Channel 4 is continuously on and off. It has a life of its own.
The log shows that it is turned on and off randomly by the device.
Can it be a software problem?
I changed the adsl router, keeping the old parameters on the new one. I turned off the old router. The 4ch pro sonoff no longer connects, even erasing it and re-adding it via ewelink and iphone. A dual sonoff instead connects well, as well as a smart power plug xsource. Restoring the old router all works well. Some idea? Is a hard reset possible? Thank you
No hard reset is possible. I advice you to relink your 4ch pro by pressing any button for 5 seconds and following the e-welink registration process.
method 1: just pairing channel 4 to your remote.
method 2: Open the shell and press inner button S5 until all LED blinking.
I've used method 2 because i dont have any RF remote.
When pressed the button S5 all led turned on, after some second all turned on.
Now it works.
Great!, another trick to this amazing device.
I have ordered 4 ch pro few back. I have set it up in self locking mode as per the instructions. I am unable to setup wifi and all 4 physical buttons are working as they are glowing when i press them. But the problem is i am not getting any output current from any of the 4 channels. I have tried with both AC and dc but no use. Any solution for this?
What do you guys use to cut the voltage down to 24v thanks.
