I have solar panels that generates electric via a Growatt inverter. I can read the current production via account in the ShinePhone app. I would like to have an automatic scene to switch on/off appliances based on the current production. Can I?

Dan, how did you get on with this please? I too have a Growatt solar system, and already have a Sonoff controller on my immersion heater circuit. Did you buy another Sonoff unit to link to your Growatt inverter circuit?

I would like to disable the immersion heater schedule when there isn’t enough battery power available. An alternative might be to fit a Tesla wifi controlled immersion heater element, which would also control the water temperature, not simply an on/off switch.
