I am struggling to figure how to get my Sonoff SV 1 ch safety voltage to trigger the relay. It is much appreciated if you willing to explain if I need to prepare Sonoff with Tasmota firmware or keep the original. I had tried all 4 pins and no relay triggered. BTW I had tried with both Tasmota as well as Sonoff original firmware, no luck.
Thank you.
