Light switch wiring / install new Sonof switch

Post by Valiceemo » Fri Jan 04, 2019 3:21 pm

Im looking to install a Sonoff T1 smart switch like this one:https://www.amazon.co.uk/Wireless-Intel ... rds=sonoff

Pulling my light switches out, I think im seeing more wires than I expected....
The setup seems a little odd, but ill try to explain...

2 switches in the lounge:
1 single switch controlling lounge lights
1 double switch controlling lounge and kitchen

1 switch in kitchen controlling kitchen.

Is what is seen in the attachements 'normal'...it just looks and feels like a bodge job to me? (Not by myself)
Can I safely and reliable install a Sonoff (or alternative)?

You can switch one of your lights of in one of two places, this is known as 2 way switching.
2 way switching usually has 3 wires at one switch and 5 wires at the other switch, that is why you have so many wires.

The down side is none of the wires are neutral, and the sonoff switch requires a neutral.

The only thing you could do is take the light down, put a sonoff unit (not a switch) in the roof space and connect it to the light. Only problem is you wont know if its the switch or the sonoff unit that has turned your lights on.
Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

Thanks for the reply.
I thought the black wire wound be neutral?
So are this switches wired up correctly and safely?

A lot of people think that because it is black it must be neutral, but it isn't.
Your switches are fine.

If it helps, you and a few others were the inspiration for me to write the following post. Please Click here
