Leaving /returning water temp from midea heat pump
Device type and model (or SN)
Midea Thermal artic heat pump
The description of new feature
Hello Is it possible to add two parameters from heat pump. It would be really beneficial to see and use leaving water temperature and returning water temperature. It would open alot of possibilities to fine tune heat pump automation.
Would do well to: compressor operating frequency and generated power

hi, Thanks for the information, but we are not sure where to add these sensors through that port. Can you give us an example? Do you have a list of all the addresses of all the registers? The registers are similar to those used with the modbus protocol. But not all users have electronic knowledge to add an RS485 converter and an ESP32.
Here is documentation of the modbus registers (at the end of the document): https://www.midea.es/wp-content/uploads/2022/09/180831_MU_M_ENF_KJRM-120H2-BMWKO-E-EN.pdf
I checked the pdf, but not sure how to proceed from here. From what I understood the integration uses the payload of the device and this is different to the Modus Information, isn‘t it?
Does someone know which bytes in the payload are for the incoming/outgoing water temperature? Did someone already implement this in the HA integration?
