I purchased a Sonoff Touch which requires a three-way wiring system for lights, however, I only have live-neutral and no ground in my old house.
As you will see in the second image this is the circuit diagram of a livolo light switch which uses a half wave essentially to regulate the ac and use that dc to power its internals. I would like to know if there is a way to power a sonoff in a similar manner? Any other solutions would be appreciated! Thanks in advance
