Upgrading a double Gang light switch to Lightwave “Smart Dimmer (2 Gang)”

[Mazzatoni]

Good evening

I have recently moved house and began to upgrade light switches and mains sockets to the light wave smart socket/switches

Wanted some advice to upgrade my 2 gang light switch

It is located in the living room and controls the living room and landing lights

The landing light can also be controlled by a one gang light switch on the landing

I have attached photos and just need clarification of connecting as I have 5 wires in old switch and the new switch only needs 3/4 wires in

Old switch:

L1 red
L2 yellow
L3 blue

And below it

L1 red
L2 black
L3 empty

New Lightwave switch:

Switch line wire out
Line wire in
Neutral wire in
Switch line wire out

If it is the wrong light switch or it cannot be installed please let me know and I can return it

Many thanks

Sorry to be pedantic but that is a light switch. A socket is a different device.
A bit like the difference between a bicycle and a car.

To return to the basic issue. I guess that your house has two or more lighting circuits. Usually for up and downstairs. If that is the case then that one switch will not work as there is only one live connection and can’t accommodate connections ftom separate circuits.
Further. The Lightwave needs a neutral and your switch does not have one at the switch!

Sorry there’s no simple answer. It is just possible to use the Lightwave product but it would involve substantial re-engineering of your lighting circuits, possibly some additional cables and you would need additional Lightwave product(s) at the other end of the landing circuit.

Perhaps I can isolate 3 of the wires for “landing” light and just install a 1 gang light wave switch just to control the living room light?

Well, you could but...... You just can't "isolate" those three wires or the landing light wont work at all. You would need to connect the red to the blue or the yellow and insulate the one you don't use.
BUT
The only place that you'll be able to turn the landing light on and off will be by the switch on the landing. That means, at night, you'll have to walk up the stairs in the dark, and you'll soon get fed up as every time you go downstairs you'll realise that you've left the landing light on.
Hardly worth the effort, IMO

Unfortunately the way your house (and most in the uk) lighting circuits are wired do not make things easy for the smart generation.
