Is it possible to force grid charging outside of a schedule, please?

Use case is that we're sometimes down to 20% before 23.30. But I'm often charging my car during the day with Octopus. I'm using Home Assistant with the modbus integration. So, in pseudo code, what I'd like is something like

if SoC < 30%
AND
if rate = 7p
charge battery from grid

Thank you in advance

You can fully control the inverter via modbus, but you can't do it when there is a schedule set up (otherwise they'll fight for control).

You can write your own scheduler, or alternatively you could set up something like predbat to control your system (and then write an automation to override predbat). I think it already has code to work with I-Go.

Ah, that's handy to know, thank you. I did wonder about conflicts. I've disabled it for now as I was getting weird things happening. I think I'll automate the whole lot in Home Assistant.
