Wanna bet that @lbbrhzn and @drc38 already understood that this is a problem for everyone who updated HA?!

lbbrhzn on Sep 25, 2023

Created a new release v0.4.41 with the workaround, pinning jsonschema to 4.19.0.

lbbrhzn on Sep 25, 2023

you guys mean set the jsonschema version in the manifest like this?
"requirements": [ 
     "occp>=0.14.1",
      "websockets>=10.2",
      "jsonschema==4.19.0"
],
"version": "v0.4.40"
thats it
I confirm it works, remember de colon at the end of websockets if you add the new jsonschema version after it.
It doesn’t work for me, it doesn’t even allow me to delete the integration…

just remove addon in hacs presing ignore integration installed
