Ideal ASHP HP290 with internal Control Unit Modbus config

Configuration
1

Hello HA community. First post so be gentle.

I would like to integrate an Ideal HP290 14KW ASHP into HA.

There is a modbus port available on the control board that is labelled in the installer documentation.

Does anyone have any information on the registers for this unit? I can’t find anything online.

Cheers
Tony

Hi Tony,
Did you make any progress with this. I’ve just had the same heat pump and cylinder fitted so would like to know if there are any options.
Thanks
Alex

There are no options I could find. Ideal have locked it down and refuse to sahre the register map.

Cheers

I’ve ben looking for this too. I think that the Ideal units are made by Midea and the modbus registers are in this database GitHub - Warm-Energy/Heat-Pump-Modbus-Database: A open database of modbus interfaces of heat pumps · GitHub

My rough plan is to get a RPi with an RS484 interface to run a getter/setter type interface for the modbus registers so I can control the system over ethernet. Then I can add support in HA.

Open to other ideas if someone has an easier path
