Help Connecting up Smart Wifi Light Switch..

Chiz · 10 Jan 2018 at 16:14

Hello,

I've gone and bought myself a Knaclean Smart Wifi light switch, thinking due to the fact I saw some neutral wires behind my light switch, this would be an easy installation. It's not and I need help.

As far as I make out:

Blue neutral cables go into N
Both brown live cables in com go to L2
Single brown live cable goes into L

I've done this and the office light is on, which is great, but the switch itself isn't operational and doesn't show either a red or blue light like it should.

(I also somehow managed to rewire the whole upstairs to be controlled from one light switch in the office, but I've fixed that

)

Anyways, in desperate need of some help here.

Cheers.

My current switch

You want to put the 2 lives that were in com into L and on new switch and 1 live that was in L1 into L1 on new switch and all 3 neutrals into N if they will fit or just use a short link from choc block to switch

The two COM wires into L
And the L1 wire into L1

Edit: arrr yes, as above.
Neutrals into N

Would have to put the L1's into L2 (as the L1 space on the new switch is actually empty)

guessing if you had the perm live in L2 then the wifi switch didnt have any power so lights didnt come on etc

ok, on it, give me 10 minutes

Nope. Nothing.

All I can think is either the neutral wires aren't working or the switch itself isn't working....?

You appear to have loop at switch wiring so you should be okay.

If you aren't sure about the switch you could wire it to length of flex and a mains plug for testing. Not without some minor risk, but if you can't handle that you shouldn't be messing with the wiring in the first place (IMO).

I have a similar issue but my initial wiring is a little different. I have black wire going to COM, a blue wire going to L1 and a Yellow wire going to L2. At the back not connected to the current switch there are 2 red wires choc o bloc together. My Wi Fi Switch only has a N, L1 and L2 input. Any suggestions?

post a picture.

It doesn't look like I can post a picture - maybe because I am new? There is the option to upload an image URL, but no option to post.

bremen1874 · 10 Feb 2018 at 15:28

It's the same for everyone. You'll need to upload it to somewhere like Imgur and then post it.

I'm hoping that has worked :-)

There you go

Thank you! Where was I going wrong? I’d like to post the other picture of my wireless switch as well.

When you're on the Imgur site pick the BBCode (message boards & forums) option and insert it. You'll get something like this:-

You also crop and resize your images on their site.
