Heat pump HWS with local network control (lemmy.dbzer0.com)

Been thinking of installing a heat pump hot water service to disconnect gas from my house.

Has anyone found a unit that has local control - not cloud based, and integrates with HA either natively or through a HACS plugin?

All I can seem to find is cloud based options with sketchy apps.

I have a daikin aire source water heat pump . it does not have any “smart”. it has a wire you plug into a dry contact to start it. so i plugged it to a shelly 1 and use a smart plug to monitor its energy usage

I cannot fine tune its temperature just start-stop it, but works well enough.

@sanzky @bootstrap what kind do you have there? Altherma? Do you have a link for more detailled information at hand?

Ive considered this as an option... as long as its just stop start and doesnt fuck with any of its other functions it should be fine.

I've got a few shelly devices doing other things already so that would probably be the easiest and most reliable place to start
