Ok, so I've got a sonoff basic and was planning to use it to control my heating unit, by connecting the line to the thermostat leads and just running a null back to the socket.
Issue I encountered is the heating unit is varying the voltage from 12v to 70v AC constantly, seemingly not enough to power on the sonoff.
What I was thinking was to get a 5v charger and connect it, as mentioned in the FAQ to D5, however, in my newbness, I am wondering if I need to cut something or disconnect, in order for it to work properly.
Any ideas how I should go about it?
Ok, so I managed to do it by connecting 5v to D5 and running just the live wire through it and switching that on and off. DIdn't need to remove any rezistors or anything and works just fine now
