No, that's another issue... Try looking here https://github.com/hultenvp/solis-sensor/issues/369

I have the same issue and it started with the update to HA 2024.6.0.

My Solcast integration seems to be affected at the same time with a similar warning and they are referencing a link to handling time zones: https://developers.home-assistant.io/blog/2024/05/19/fix_zoneinfo_blocking_io/

[pivlersmom]

Same issue here. Integration is not loading anymore

[dpgh947]

I am getting this since updating to 2024.6.2 - I also had the same for the alexa_media integration, but that has already been fixed. I get the error at HA restart, but the solis integration does seem to load and work OK after that.

[changeofaspect]

I had similar with the Solcast integration which generated a message at start up and a slightly different message every time I polled the Solcast server. The warning message for the Solis integration points to Line 185 of the soliscloudapi.py file which is with open('/config/custom_components/solis/workarounds.yaml', 'r') and seems to be trying to open a file in the event loop.

The Solcast integration has now been fixed by using 'async with aiofiles.open' instead of 'with open' but it was not quite as simple as that. I am not a Python coder but I noted that other changes were required to be made to make it all work. It will need a Python expert to work through it and make the changes - I am definitely not a Python expert. Also, the reference above to the zoneinfo blocking turned out to be a bit of a red herring, yes, it needed sorting, but it was not the cause of the warning messages which were caused by the 'with open'.

Hi all

I'm getting the same error and notes on work grounds or anything like that? Below is my error
