Unusual to see UKCA, and even more so without CE. What I can’t work out is the terminals!

Their website has a wiring page, seemingly AI, which eventually has one line saying wire according to manufacturers’ instructions. This is on the wiring instructions page in the manufacturer’s website, FFS.

Another page, very similar, refers to COM and L1

Dimmer switch, UKCA marked, with terminals marked ~~, P, and L

Sparky worked it out or has better search skills than I.

Left – ~ (wavy symbol): Dimmed output to the lamp (switched live).
Middle – P: Push-switch input (for an external momentary/retractive switch).
Right – L: Permanent live supply (230V).

@revk ah, a no-neutral thing. I get how those are useful for retrofits.
However I'm spoiled by this house having live, neutral, ground and switched wires everywhere. It's a luxury I'm thoroughly enjoying.

@tbr @revk Arguably it does have a neutral, it just passes through the lamp first.

I have to use those as it's all switched live in this house. Works well enough although they're often too bulky to go into the switch and require masonry work..

@tbr Indeed - hence also putting up with zigbee. I usually use WiFi and MQTT, but have had to now install a zigbee2MQTT thing.
