Hi guys and girls…

I need some help with smart light switches for the uk. I’ve had a look at the back of my current standard switch which looks like the image attached

This is a 2 gang socket which controls ceiling lights and lights under the wall cupboards in a kitchen. We want to keep the same functionality.

From I see/ understand in the picture

COM - this is the Live cable - there appears to be smaller piece of wire connecting both “COM” terminals but also an individual wire feeding straight into the terminals

Neutral (blue) - this isn’t connected but is there so I assume I could buy either smart switch type (requires neutral and does not require neutral) there appears to be 4 wires in a terminal block why 4?

There are two L1 sockets at the bottom which I believe feeds the lights themselves.

If I were to buy the switch attached, how would I wire this up?

The brown wire that goes to the COM on the old switch goes to L on smart switch

run a bit of wire from the neutral block to the N terminal. CBA to explain why there are 4 there already.

Thst will leave you with a couple of brown wires on the L1 terminals on the two existing switches. Those will go on the output terminals L1 L2…

If your smart switch has an earth terminal then earth it.
