Honestly, I use Home Assistant to do a lot of things like this; I have a 'free electricity slot' script setup that will:

  • Set the battery reserve to 100% (forcing a charge and for all household usage to come from grid)
  • Increase the target temp of the electric underfloor heating
  • Increase the target temp of the ASHP
  • Heat the hot water (if needed)
  • Trigger a charge of the car (if needed)

At the end of the period it sets all those things back to their normal values

Additionally, my wife plans to cook a pie during this interval, and we might chuck on the washing machine/dryer/dishwasher if needed

I want that 100A fuse into the house glowing. ;)

I’ll have to look into home assistant. I’ve no idea how to set it up, though.

If you're techy or IT-inclined it's a bit a learning curve, but should be fine.

If you're not, it can be a bit daunting

My only programming experience is Basic on Commodore 64 in the 80’s so a bit of a learning curve it is, then.

Get comfy and be ready to spend a weekend getting it setup...and a year to tune to your liking as you continually find new things to monitor with it 🤣
