Hi GreenTurtwig,
I should have posted something here straight away after jsock let me know about this post, but didn’t get round to it.
Basically after not performing a good search for hive integration I decided to create a custom component for hive heating and hotwater, which sounds like it does a similar thing to yours, I have posted about it here.
Tonight I should be updating the post with a new version (once the latest tests have gone successfully , so far so good) which is much more scalable and I am hoping should be able to integrate all the Hive components (heating, hot water, lights, plugs)
My fault for my dodgy search in the first place, but would you like to combine efforts on this?
