@dpressle - Nice work!

[Toyman]

Can it be installed as normal in-wall switch ie with one wire only? or it needs both L and N 220v wires?

You would need both L/N. The node requires power to operate.

I've only seen a few dimmer solutions that can drive themselves (with only L) by letting a small current pass through the load all the time. This is not possible when dealing with relays.

[Toyman]

Thanks. AFAIK, Livolo switches can do that

Hi, I like your project. Can you share the schematic? I maybe would like to minimize the print by using only 1 relay channel. Thanks in advance.

[dpressle]

@Lucien Sorry for the delay, i will post it soon.

What kind of Solid State Relay do you use? Can you switch 230V/4W LED bulbs with this Solid State Relay? I tried some "Songle" relays once and that causes the bulb to flicker all the time.

I like those relays. Is that 3 different switched outputs? One thing I always liked about european wall switches is that they give you more room for components. I would like to use a similar type of relay for my in-wall switches, but with the way US single gang wall boxes are, there is a pretty narrow space constraint. I might be able to fit it if I did away with the thermal fuse, but I don't want to give up tat bit of added safety just for that.
