I was wondering if someone could point me in the right direction. I have been planning to build a solar diverter for a while now in replacement to my old one.
I have a emontx shield and arduino Uno ready to go. Has anyone done this before? Be an interesting little project.
Question is where would I connect the 3.3V to my SSR for the switching of the immersion heater. The spare terminals appear to be for the DS18B20 sensor.
Any advice or pointer would be much appreciated.
