Thanks for the tip.

Yes have seen this before, it looks like the standard wiring. Unfortunately my problem is I actually don't have access to the neutral wire...

Got a consult and a glaring problem turns out the neutral wire I thought plugged in actually turns out to the neutral wire for another light :shock: [...] And when this was on another phase, you essentially fed 400V into the Sonoff. I know some CoCo 433 MHz switches were said to be able to work wit...

sigh, thanks for looking all

(I've al...

Hi Looking for some advice to what's hopefully a silly question. I'm trying to install a Sonoff DualR3 to a 2gang 2way switch setup. Appreciate that Sonoff provides standard wiring as below: Screenshot 2023-02-01 214311.png However the actual 2gang 2way wiring is (likely) per below (and in any event...
