I wanted to mention that I added support for heat pumps and posted about it in the thread on testing the v1.5-dev release.
It’s undecided if this feature will make it into the v1.5-dev release or will be in a future release, but feel free to chime in on the thread linked above if you would like to get in your 2 cents.
cc: @N0YKG since you asked about something similar in another thread. What I did isn’t exactly what you were looking for, but it’s very close. And @jay too!
