Not able to add comfoair to home assistant: timeout error

[threster]

When trying to add my comfoair q350 to home assistant with this integration, I always get a timeout error.
Comfoconnect U1.1.10

Logger: aiocomfoconnect.bridge

Timeout while waiting for response from bridge

[MatevzBokalic]

I also get a timeout error. (Disclaimer: I am a very new HA user and this is my first custom integration)
Running: HA OS 2024.12.5 on RPi 5, ComfoAir Q R1.10.0 with ComfoConnect Gateway R1.5.1

I installed HACS, added github repository, downloaded Home Assistant Zehnder ComfoAirQ / ComfoCoolQ integration.
When I try to add integration, Zehnder ComfoAir Q is found, it even finds ComfoConnect LAN C bridge and offers 192.168.2.113 IP, which is correct. Then when I click submit, in a few seconds Unknown error occurred message is displayed.

home-assistant.log has the following entry:

If i try to add the following to the configuration.yaml:

comfoconnect:
host: 192.168.2.113
token: "00000000000000000000000000000002"
pin: 4210

sensor:

• platform: comfoconnect
  resources:
  • air_flow_exhaust
  • air_flow_supply
  • bypass_state
  • current_humidity
  • current_rmot
  • current_temperature
  • days_to_replace_filter
  • exhaust_fan_duty
  • exhaust_fan_speed

  • power_usage
  • preheater_power_total
  • preheater_power_usage

I get very similar logs:

Note also that I may have misread the instructions to manually configure configuration.yaml file where token should be added as a string, and default should be in quotes. If there are no quotes additional exceptions are thrown when trying to convert to hex.

I have also tried other combinations of pins and tokens, but no success.

The Zehnder app on the phone works perfectly.

Thank you!

Same error.

I think the porblem is the ComfoConnect PRO module is not compatibel!

[MatevzBokalic]

I have ComfoConnect LAN C interface but am unable to connect.

I have also tried connecting directly using python library aiocomfoconnect on my computer but also failed.
bridges = await discover_bridges() responds in one bridge at 192.168.2.113 with UID different to 32 zeros.
However await comfoconnect.connect(local_uuid) never returns.

Any ideas or help how to continue? Thank you in advance!
