Trying to install TCP wifi switch.

[Zaraktoheed94]

I recently bought a TCP wifi switch and tried to install it my self.
Behind my room light switch i have 2 red and 1 one black wire.
I tried putting one red in lin, one red in load 1 and black in N but unable to switch the switch on.

i have tried every possible combination the wire might go but unable to switch it on.
I tried plugging 2 red together in Lin and Black in N, the light stayed on but the blue light on switch didnt come on.

please can anyone assist me on which wire goes where as none of the electricians i know arent willing to help.

it's possible that you do not have a N at the switch position. a pic. of how the original switch was wired would help.

Thanks for a reply.

At the moment one red wire is in L second red in L2 and black in L3 on a current switch.
Would this help or do i need do something els?

as i see it, youneed the live feed in Lin, the switch wire to light in Load, then light will work. however, it seems you need a N in the 3rd terminal to enable the switch blue light to work. have you got a pic. of the instructions wiring diagram?

There were no instructions in the box as it only said attach the switch and download the app but i managed to find a diagram online as attached.

Unfortunately, you need a neutral for the switch to work correctly.
Do you have a picture of where the wires went in the old switch?

Had to take the picture without my mrs knowing as I ruined the wall yesterday. ??

Hi James,
Thanks for the reply, please see attached picture of the old and new switch.

the old switch is 2 way, so there's another switch for the light elsewhere. to make it work properly would require some re wiring of the switches to lights. if you get the switch working with existing wiring config. thast's a bonus, but you'll never get the switch illumination without providing a neutral at the switch.

The WiFi switch requires a neutral to power its internal electronics. The black wire at your original switch appears to be a 2-way strapper, not a neutral, therefore the switch cannot work with your existing wiring as it is. Whether it can be rejigged without chasing out your walls to add a cable, or whether you will have to replace the switch with a type that does not require a neutral and possibly add a dummy load to power it, will depend on exactly how the cables have been run and what lights it feeds.

In any event, I would advise against trying random combinations of wires when you don't know what is going on. Product damage and personal injury can result, also fireballs and other unspecified apocalypses.

Out of curiosity, did your original switch have an earth cable?

Mine does but was not in use with the original

It most definitely is in use. It is earthing the back box and the fixing screws.
If you're trying to do the same thing as the OP, you have the same problem - no neutral.
