Hello,
I have an Immergas Magis M14T heat pump (which I believe is a Midea clone):
Immergas Magis M14T
The control panel includes Modbus A and B contacts (also referred to as H1 and H2 in the manual).
I recently purchased a Waveshare RS485 to Wi-Fi converter, but there is no available documentation on coils, registers, or other Modbus details, unless similar heat pumps share the same configuration.
Hoping someone can help!
I haven’t that HP but from a very rapid search, if it’s indeed a Midea clone/rebrand then this could work:
I saw that. But I can’t find that integration and install it
Actually, I managed to add the repository, but when I install it through the integration menu I get
Sorry but I have not that integration, you could try to open an issue on the repo page hoping the developer still maintains it.
From the commits it appears that the modbus register map came from an hungarian website
from the KJR-120X user manual
If it’s similar to the one you have you may find the map is applicable to your HP.

or see if this is applicable:
The link to midea was originally for wifi support, but in the end it was kind of hijacked by modbus protocols (so you’ll have to search at the end)
