Wiring Sonoff Touch Smart light Switch

benhur999

Sorry to piggy back thread, but a lot of you really know this stuff!!! I’m getting power and the switch can be heard to turn on but no lights!!!! Any ideas?

Sheathed neutral wire looks like it's a switched live to me, so won't work.

Jamie

Agreed, that's live and switched return, there's no neutral in that switch.

Also piggy backing, hope that's ok
I think I know the answer but gonna ask anyway. We have a very old house, I have 3 wines to my switch, black, red and green/yellow. Will the sonoff work?

Jamie

Short answer No

Long winded vebiage hopefully to help others understand what they're looking for.

I'd say no. If you've got a neutral in the switch you'd have a couple of extra wires in the appropriate colour  (black on older houses, blue on newer ones) that are terminated together in a terminal block or twist on connector and not connected to the switch.
The black wire to the switch should technically have a piece of red sleeving on it to denote it's actually a (switched) live cable and not a neutral.

Jamie

Oh and PS. 3 wines to the switch, cheers (hic)

Beqi

Yeah, I thought you were gonna say that

Hi everyone, great thread and hoping you guys with knowledge and experience can help me out here. Looking to install sonoff switch but after reading this I’m not sure it will work. I have a passage way with 3 x leds in ceiling. I have 3 light switches in passage way all turning the 3 x less on/off. I have taken light switch off wall and see 2 wires going into com. Wires going into L1 and L2. There is a block with I think 3 blue wires going into it. Do I have the ability to install this sonoff? If I can, how do I wire this up as the sonoff only has live in and live out?! Just taken off light switch. There 2 brown going into com, 1 x grey going into L2, 1 x black going into L1. Both L1/2 have a brown sheath. Neutral attached to plate ground. I know this is a tad more complicated than the norm but am able to sort or just forget this solution? Any help is greatly appreciated!

I’m I correct in thinking both L1and L2 go into live out on the sonoff switch. 2x brown in com go into Live in and 3x blue in block go into neutral?
