[maestrigia]

I installed the last Toyota 2.0.3 version from HACS, it failed when I added my Toyota credentials, look below the error message:

Yep, I stopped by to confirm I have the same issue

[MarcoZ76]

have the same issue too

I've got probably similar/connected issue:

Detected blocking call to open with args ('/root/.cache/toyota_credentials_cache_contains_secrets', 'r')

also at custom_components/toyota/__init__.py, line 56, my traceback looks different tho, but in addition I see this link in my log - as a hint, may be useful:

Try updating to version 2.0.5, this should be fixed in the latest version.

updated to 2.0.5, I've noticed that fuel level is back [it dissapeared few days earlier and I couldn't bring it back no matter what ;)], but still can see some issue similar to the above mentioned, but now it's another line in code. current warning in log:

This is not really a problem with the ha_toyota custom integration, but rather with the mytoyota Python lib used.
This lib does write (non async) a file with the cached request responses to the file system when it is initialized, which causes a blocking call.
