Trying to add my ventilation unit via Modbus

Hi,

I’m trying to add my ventilation unit vid modbus. But i can’t find any entity after i restarted HA.
I guess the register key should be something else?
According to the supplier, the register key is 3x00002, but that’s not a valid to add.

Thanks.

In my config i have:

modbus:
  host: 192.168.86.124
  name: hub1
  type: tcp
  port: 4000
sensor:
  platform: modbus
  registers:
    - name: Outdoor temperature
      unit_of_measurement: °C
      register: 00002
      slave: 1
      register_type: input

The suppliers Manual:

I checked on my control panel to my ventilation unit. Modbus is on, TCP/IP. Port 502, so i changed the port to 502 in the configt. still not working :frowning:
