i installed sonoff light switch but light keeps blinking. Wiffi and touch seems working properly but light blinking always
Here is a prove that not only me and you Huzeyfe have this problem: https://www.youtube.com/watch?v=jO_HCB1a0p4. Strange enough, but there is no solution listed anywhere in the net and I'm wondering if there's a workaround or it doesn't work at all. Please help with advise!
hi Stanislav Dinev, i solved the problem with electrical technician.
the wiring system should like this The Notr wire goes in L, phase goes in N then the other cables goes in L1 and L2 then light blinking goes and the switch work properly
You need 3 wires.
Always Hot wire (usually black)
Neutral wire (usually white)
Switched Hot (usually red) connects to the light bulb
Using the above color codes which are not standard all over the world:
Black to Line in
Red to Line out
White to Neutral
If there is a green wire or yellow/green wire or bare wire in the box it is an earth ground. Do NOT use the ground as a substitute for the neutral.
In old construction quite often only the hot and switched hot are present in the switch box. The simple switch just makes or breaks a connection between them. With the IOT switch the electronics require a power source and thus they require a neutral wire be present. If you do not have a neutral wire you will need to rewire and pull one else you cannot use the IOT switch.
The ground wire connects to nothing but the frame of the metal boxes. The little 3 dash symbol represents the frame. Do NOT connect the ground wire to the Sonoff in any way! Once again, you need 3 wires in addition to the ground wire. Line in, Neutral, and Line out.
Glad you got it working.
