AttributeError: 'Bridge' object has no attribute 'connect'. Did you mean: '_connect'?

[roofburner]

Hi,

I ran this integration successful for a long time, but I no face this error after a power down/up of the Zehnder unit.

FYI: I successfully connect to the unit via the smartphone app...

Installation spec:

Home Assistant (docker)
  --> Core 2024.4.1
  --> Frontend 20240307.0

Zehnder ComfoAirQ integration via HACS
  --> v0.1.10

ComfoAir Q350 B R ST ERV Prem
  --> Firmware: R1.11.0
ComfoConnect LAN C
  --> Firmware: R1.5.1

I try to add the Zehnder, but I face this error:

I'm not able to run a debug, but in the logs I see (tcpdump below):

Extra info: I installed aiocomfoconnect (https://github.com/michaelarnauts/aiocomfoconnect).

# python3 -m aiocomfoconnect discover
Discovered bridges:
<Bridge 192.168.0.177, UID=00000000001210138001144fd71e1811>

What else can I test?

[roofburner]

I did some further testing: I can control my Zehnder via the "build in" integration, i.e. https://www.home-assistant.io/integrations/comfoconnect/

Thus, I decide my ComfoConnect LAN C isn't broke...

Same error occurs for me when trying with 0.1.10. Downgrading to 0.1.9 works for me.

[roofburner]

I did some further testing. It seems, when you want to install v0.1.10, you first need to install v0.1.9 and then upgrade to v0.1.10. You can't install v0.1.10 "from scratch". Strange...

I just followed errors: https://github.com/michaelarnauts/home-assistant-comfoconnect/pull/49/files seems like methods at source were renamed with leading underscores and code in this repo wasn't alligned. I am not sure if that's enough to make it compabile. However, worked to run the integration. https://github.com/michaelarnauts/aiocomfoconnect/compare/v0.1.9...v0.1.10#

[michaelarnauts]

This is indeed the fix. Thanks @krismarc!

I'll make a new release with this fix.
