Improve efficiency: Turn the heat pump off

@borpin although a few of us have written scripts, Chris doesn’t want to. This is part of the reason for open-sourcing our scripts and results, so the manufacturers can build the adaptations into their devices for regular users. I suspect the UK is a bit awkward because we have so much of the time when we’re around this 10 degrees phase which is tripping up the heat pumps control algorithms and causing cycling.

BTW @cre at least your cycling isn’t as bad as this:
