Hello, I'm new to shelly, and hoping that someone here can help me out.
I'm trying to create a scene on the app that will allow me to use the electricity that I send to the grid left over from my solar production. I have a Shelly EM and a shelly 1pm. When I'm using less electricity than I'm producing, I get a negative value from Shelly EM. When this happens, I would like my shelly 1pm to switch on to power an electric heater, to make use of free energy. Maybe there's a newbie guide somewhere?
Cheers
