Error doing job: Task exception was never retrieved (None)
My log files are full with aiocomfoconnect issues, seems a connection issues (see screenshots below)
What I have tried:
- Reinstalling the integration without success
- Check for connectivity issues between HA and LAN Bridge, non found
- Reset the LAN bridge
Environment Core 2025.4.2 Supervisor 2025.04.0 Operating System 15.1 Zehnder ComfoAirQ version: v0.3.0 Zehnder ComfoAir Q600 Zehnder ComfoConnect LAN C
Any ideas?
It stops working also frequently.
Can this be a result of firmware? I would also expect the hub to be shown here? But instead the hub is shown as a demo device without entities
In the ComfoControl iOS app I am seeing that I have firmware version R1.5.1
Thanks!
I also see those same messages in my logs. Does anyone have a solution to this problem?
Same issue for me. It works for a while, and then I start getting timeouts every 5 seconds. Interesting is that it started exactly at 3AM
