Having just had solar and a battery fitted by Octopus I'm interested - would you mind sharing what you use for automation here please?

Sure, I use Home Assistant running in a little raspberry pie in the lift.

There is an Octopus Integration that exposes current prices (and much else) to HomeAssistant.

There is another Integration that works with my solar panels and another that works with my batteries and can change mode (self use, force charge, force discharge etc.)

So from there it’s really just a question of setting up some if-then automations to turn on smart switches, charge the batteries if prices go negative.

You can also gradually add more nuanced automations like turning on water heaters if the panels are generating more than 1kW and the batteries are over 90% charged.

I’m not a programmer, it’s all fairly easy to do.

Thank you, that's really useful.

Not op but may I suggest looking at Home Assistant, Octopus Energy Addin and Predbat: https://springfall2008.github.io/batpred/energy-rates/
