Shortly after updating HA to 2024.7.x it began reporting errors like this:
Detected blocking call to open with args.....
… followed by endless lists of Python 3.12 references.
These blocking errors were never seen before - ever! Now they flood my log daily and every time I restart HA. I do not understand what they mean, nor what to do with them.
I could see however, that some integration maintainers have released updates to prevent/fix blocking calls for their integrations so obviously this is something “new” that we didn’t have problems with earlier.
Regretfully, many maintainers either no longer maintain or they cannot/will not step in and fix this. I assume that if they use their own integrations, they too must have seen these errors?
