does this register contain COP or SCOP?

Hi
Will we be able to read these values ​​using the Custom sensor? Unfortunately, I am not a programmer or IT specialist, but I understand EspHome as a Home Assistant user.
0x4426 | LVAR_IN_?? |   | Generated power last minute |  

0x4427 | LVAR_IN_?? |   | Total generated power

I have for INTERNAL unit (20.00.00)

      custom_sensor:
        - name: Produced energy
          message: 0x4427
          device_class: energy
          state_class: total_increasing
          unit_of_measurement: kWh

I don't know if it works with 0x4426, depends on the fact that the heat pump send that data over the network or not. You can try and give us a feedback regarding the device you have and what you tested.

PS: check the correct state_class between options at https://developers.home-assistant.io/docs/core/entity/sensor/#available-state-classes . Probably right is measurement because value is updated every minute without considering the value in the previous minute

Hello, today I managed to sit on it. My device is an AC052rnndkg/AC052rxadkg duct air conditioner. I am attaching a file with logs and others. The control functions work and I read a lot with the custom sensor. Perhaps this model does not have the ability to read COP?

I didn't tested all your address, but it seems probable to me that some values are not sent over the network if they don't work.

I didn't understand the voltage value: as in the posted screen i mostly read 206V even if I have 230V+-10V at home. Maybe it's meaning something different

[Krzysiek1976]

voltage and current measurement values ​​are indicative because a calibrated meter shows higher consumption.

Voltage is not indicative, it's wrong. I don't have a dedicated power measurer for heat pump, but comparing with house voltage (that's not constant due to photovoltaic production) i can see a strange trend:

If heat pump is consuming power, home voltage goes down (as expected) but read heat pump voltage goes up.
All measured voltages in the house are not seen by heat pump value.
