Blocking Call to load_default_certs at Startup #1047

dsbanfield · 2024-09-28T13:59:35Z

Is there an existing issue for this?

I have searched both the existing open issues & recently closed issues and did not find a duplicate of this issue.

I have read about the Fleet API and understand I may need to use it

I understand issues relating to read only commands will be auto closed if not using the Fleet API.

Version of the Tesla component

v3.24.1

Version of the Tesla car software

2024.32.3

Model

Model Y

Current Behavior

During startup of Home Assistant, I get a traceback in the logs, generated by the Tesla integration component. I am encountering periodic crashes of my entire HA instance and this is something that has shown up in my diagnosis of that larger problem. I am not asserting that the Tesla component is the cause of my crashes. I have not concluded that analysis yet.

Expected Behavior

Tracebacks are not expected to happen in normal operations.

Thank you for locating the earlier report of this issue. It indicates it was resolved and the fix was merged to the main repository? Is it not in the current main release (3.24.1)?

gedger · 2024-10-12T17:20:39Z

I've confirmed I'm running 3.24.1 but seeing the same error.

It appears this issue (zabuldon/teslajsonpy#474 ) has been worked and accepted(?) into the main code base. What is the process and possible timeline for an official point release containing this? TIA -Dean

alandtse · 2024-10-13T01:18:15Z

Someone submits a PR to add it.

jvaartjes · 2024-10-18T05:39:37Z

I have the same issue.
I have tested version 3.24.1 against teslajsonpy 3.12.1 which has the proposed fix [https://github.com/zabuldon/teslajsonpy/pull/474]

Running HA version: 2024.10.2

It does not solve the problem as now ssl_context has no value? I hope my output helps in solving this problem.
