Midea Wired Remote Controller KJR-120

[wizardmelon]

Hello,

I’m planning to buy a Ferroli Heat Pump that uses a remote wired controller based on the Midea KJR-120 Modbus mapping.

After comparing the mapping from the file provided with the remote control to the addresses in the YAML file published here, many of the addresses don’t seem to match. Unfortunately, I’m not very familiar with RS485 protocols, and I was hoping someone could help me understand how to modify the YAML file to make everything work.

I don’t have the heat pump installed yet, so I’m unable to run tests at the moment, but I want to start writing the ESPHome code and have it ready for when the heat pump gets installed.

Any help would be greatly appreciated!

Thanks
