Trigger when solar starts to export


So I was SURE this was a feature already, but I can’t figure out how to set it up…

What I want is to know when the solar production exceeds the house consumption, and when it falls back below it, so I can (for example) trigger my water heater to boost the stored water temperature…


Yes that is one of the things I would like also. I asked for something like that a while ago but got a standard “working on it” reply. In the meantime I bought a used Nuerio which gives me that data now.
I am also working on a Hybrid inverter powered by Nissan Leaf batteries and would like to use that trigger to charge the batteries from solar.
