I’ve a Samsung Heat pump and an Agile tariff. I’ve been controlling it for the last year using an ESP module and automation.
I’ve not found any posts on the subject so it looks like I’m the guinea pig! I’ve just signed up for Havenwise control to see how it works. They allow a trial for three months so I figure it’s worth investing.
Watch this space…
Haven’t been able to find an integration, so HA is now just monitoring what HavenWise is doing with the heat pump. HavenWise seems to be doing a nice job of controlling the heat pump and seeing lower spend after a couple of weeks.
