Problems getting values from CTC heat pump via Modbus

Configuration
1

Hi all!

This is my first post here, I have been reading a lot and getting great help, so here is hoping for more of the community goodness!

I am trying to read values from my CTC heat pump via Modbus and am struggling to get the values into Home Assistant. I can read the values using an external tool Modbus Poll, see picture:

However, I just cannot understand how to translate the above into configuration for Home Assistant. This is what I have so far:

- type: tcp
  host: 192.168.1.187 # CTC EcoZenith i360
  port: 502
  name: "ctc"
  delay: 5
  timeout: 5
  sensors:
    - name: "CTC Aktuell rumstemp"
      unique_id: ctc_current_room_temp
      slave: 1
      address: 62203
      input_type: holding
      unit_of_measurement: "°C"
      device_class: temperature
      state_class: measurement
      data_type: int16

The sensor shows up but without values and is listed as unavailable.

I have other sensors set up using Modbus coming from my Solar inverter, so Modbus in general, is working.

Any ideas what I am doing wrong?

@mikhul did you sort it out? I have gotten the modbus integration configured, but I get some errors that its not connecting appropriately.
