And...here comes the 1 channel variant for the classic Livolo switch front plate. Work in progress for both projects(1 and 2 channels)...

Am I right that Livolo needs just L wire, and not both L and L wires? Is it the same when Livolo front panel is replaced with yours? If yes, then it would significantly simplify the install process

@Toyman

Yes you're right. And regarding the second question - the functionality is the same but you have Mysensors features on top.

[Toyman]

Thx! I mean "when replaced with yours still needs just one wire", but it's clear now!

@Toyman

Yes I know what you meant. It's L(live) wire only powered. But in order to work it still needs a capacitor across the light bulb as I mentioned in the other project(https://www.openhardware.io/view/306/Livolo-2-channels-1-way-EU-switchVL-C700X-1-Ver-B8) and some modifications on the power board but this time without the 12V line wiring as it's already provided now in the new version by the Livolo manufacturer.

[mtiutiu]

I wired the relay channels inputs in parallel on the 2x7 connector as this variant has one relay/channel only but I don't know to which of the ULN2003 IC outputs the relay is connected to on the power/relays board. So basically two of the current buffers from the ULN2003 IC have the inputs tied in parallel which I don't see to be a problem as this IC is designed to have buffers put in parallel(both inputs and outputs).

Hope that the above makes sense.

Wooow Wooow Wooow ! Here they are !

This one gang you designed will be my 1st Livolo hack
So many many thanks @mtiutiu

Best regards
