Hi all, I'm trying to hookup a sonoff to switch power on/off to a set of thermostats in my radiant floor heating system. The power supply is a 24v supply thus my trying to do this with a Sonoff SV. The power supply is here:
I've attached a picture of how I wired this up, positive (red) to in+. When I plugged it in the resistors below the input blew/popped.
Did I wire it incorrectly or should I be using a Sonoff Basic?
