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.
Hot water heater? Yes, I did find it.
I specifically bought a Rheem (“Performance Platinum” model) last year because I can control it with Esphome.
Little M5Stack Atom controller with rs485 module plugs right into the port on the water heater, using a simple old-school modular phone cord. I do not use the water heater’s wifi or Rheem account/cloud service.
It works great completely local from HA. I automated it to boost the thermostat setting extra high during lower electricity rate time of day, and lower the thermostat during peak billing time. So I can bank extra stored heat, for less cost.
I added a thermostatic mixing valve on output, to ensure regulated safe temperature to pipes and fixtures.

I have the same setup. I haven’t done much with it yet, but it seems to work well with the water heater.
This is gold thanks mate
Would you mind sharing the exact model number of your Rheem, please?
Great job!
I bought model # XE80T10H45U0
Looks like it has been replaced with a slightly newer model:
