March 6, 20233 yr Have a smallish inverter and solar setup and looking to optimize via software. Does anyone know if its possible to set an automation in Home Assistant via Solar Assistant for instance: When PV input drops below 50w, within 2 hours of load shedding, to charge battery via utility only? Guess the main thing here is does SA allow these sorts of changes via HA? Many thanks Edited March 6, 20233 yr by sunset1

A number of settings need to be correct in both Solar and Home Assistant to get it working but once that's done it works 100% Home-Assistant setup MQTT integration Work through these resources and see how far you get

Then it all started to look upside down.

If it is an Axpert/Voltronic I think you can just connect home assistant to it directly. https://github.com/ned-kelly/docker-voltronic-homeassistant

Think of it like a Pen-pal mail system You use the Sub command to subscribe to messages You use the Pub command to send messages The format is specific to the inverter,you can practice sending the commands via Pub to solar-assistant and see it apply to the inverter. Then it's a case of having HA send the command when the relevant conditions are met
