Seeing the same issue on a fresh HA 2024.9.1 docker install with new Tahoma switch powered on. Let me know if any additional info would be helpful and I will provide it.

[mvaneijken]

Same here, but in my case it started today. I'm using the local developer API on a Connexoon IO box.

[mvaneijken]

I removed the configuration from Home Assistant and then added it again using the IP address instead of the hostname. That works for now.

[iMicknl]

@mvaneijken it is a warning and should not block the use of the integration... This error is caused by the 'SSL verification' option. This needs to be fixed in the underlying library.

Due to limited time of the contributors, I can't give an ETA when this warning / issue will be fixed.

[mvaneijken]

I see, there are more integrations failing because of this. Main issue on Home Assistant Core can be found here: #125993

[zeratul021]

Had the problem on 2024.10.1 and after update to 2024.11.1 still appears.
