Smart switch wiring

[Tigerdim]

I know I should probably get an electrician, but was wondering how easy it would be to switch my regular switches to smart switches. (After switching off the power naturally)

 

The current wiring doesnt look like anything I find online. Is it just a case of sticking the 2 black and 1 red into the L1, L2, L3 and then the white into the L?

 

The electrician who wired my house said there was no neutral wire on the switches.

Probably white into L and the others in the Lx terminals.

Try. And be careful. 

 

And about N: Look in the manual. Maybe it works without N, under certain conditions, maybe.

Thank you. As there are 2 ends on the white. Should they be put together into the L?

I guess yes.

 

But best wait until Crossy answers.

I use Shelly devices.

You will find lots of wiring diagrams here:

They might be helpful for you.

Ok, it's brown.. being colour-blind I could have sworn that was red!

 

Thanks for your help.

Check what is live and not with one of those very cheap  mains test screwdrivers before doing anything  the colour of the wire means nothing.

So will poking around with a test pen unless one knows what they are doing.

 

You will find most correctly associated the existing connections with what was required in the new arrangement.

Colours quoted were to guide the Op in the right direction.

Looking at the picture above the while cable is clearly input, it connects to all 3 switches.

My guess is that the two blacks and the brown run power to the respective receptacles…

the whites are all the same providing load current… there are probably two whites coming in because one is the load wire and the second is daisy chained to provide load to the next adjacent switch on the wall…

Put the two blacks and brown on the L1 L2 & L3…

The two whites put together and put  in L

Much easier to replace the bulbs with smart LED/WiFi jobbies than 5..king around with wiring switches.

That may not be easier… I have a similar triple switch for my living room… Each switch controls a bank of 5 pot lights… So replacing the switch would be easier than replacing and programming 15 lightbulbs… Also the switches have to always be in the on position so they are useless… Then I have to train my Thai partner to NOT use the switches and instruct him on the use of an app instead…  😀

OK, or as your Thai partner might say, up to you.

 

Once programmed, it is so good to have lights come on and off, brightness, colour etc without intervention. Works on my Aircon and Purifyer too, and can control with my Amazon Firestick remote, or Google.

Unfortunately I have a chandelier with around 50 bulbs, then there's all the garden LED floodlights. Changing switches is definitely the better solution for me. 

I have some Hue light bulbs for the lights I want to be able to adjust.

 

I decided to get an electrician to do it all. Much easier for the small cost of it all.

 

Thanks everyone for your inputs.
