Hello, I've got a small dilema about something, and would appreciate if u could give me your thoughts on it. Like many people, i have no neutral wire installed behind switches in my apartment, so ive got to use some way to overcome that. But, there is one thing that, I think, makes it easier for me. I've got two live wires coming from the switch to ceiling light, so i was thinking of sending one live directly to the light fixture, where i would put smart switch module, and the other one could be controlled by fiscal switch, which would pass 220v when on. I know there are solutions like Shelly 1 and others who accept 220v as external switch trigger, but the only thing I have available for me right now is Sonoff mini, which as u know uses low voltage ground for external switch. My question for u is, what do you think the best solution for using 220v to bridge S1 and S2 inputs would be? I was thinking of high voltage relay of some sort but am really curious of your opinion non that? Thank you in advance.

@@petar. yes it is possible to use a relay with a 220 volt coil. The relay contacts can then bridge S1 and S2. You can get quite small relays that have a 220vac coil, but they tend to be rather expensive. It might be easier just to use a Shelly1. But the relay will definitely work.

The "tuya type" smart switch should in theory work. BUT! People have reported them working, but on some of them the diode polarities need to be reversed, on all the diodes(and capacitor polarity). You can easily test that by powering the "tuya device" through a diode on the neutral, to test which polarity works. Then you arrange all the diodes accordingly. Also this video is quite old, and I've since improved the circuit by adding a diode and capacitor to the LED bulb. This prevents any unwanted flickering in some types of led light bulb. Like in this newer video, the diode and capacitor is included. kzitem.info/news/bejne/mp6HrHqpe52plIo You can probably build it on a prototype (Perf board) pcb.

I'm not sure if it's a problem. But I don't think the light switch is ever considered safe isolation anyway.

Lots of new electronic style light switches have leakage current across them, so they aren't truly "On Off" switches. Think of the "no neutral" type switches(and no neutral PIRs). If you wanted it to be safely turned off, you turn it off at the circuit breaker by the fuse board. Wiring regulations are different in each country.

With the 2 wire system it's more tricky, the incoming live is at one switch and the outgoing switched live is at the last switch. So it's more difficult to put the diode across both ends🤔🤨.

You might get terrible Wi-Fi reception if your switch back box is made out of metal. But if you put the sonoff mini by the light fixture itself, you might get really good Wi-Fi reception.
