And ideas please @wxt9861 ? I’m in a world of pain…!
I dont use ESXi at home, but being a VMware specialist and architect at work I admire this 
You’d get more help if you added the answers to the following questions to your post:
What version of HA?
What version of the integration?
Anyone experiencinf problme with integration not starting after upgrade to 2022.7? Itried few times to reconfigure, restart etc, but integration does not strt and always get error message in log:

Nope my ESXi stats is working just fine.
What ESXi version?
Can you see the values if you go to the development page?
The host is on ESXi 6.0 U2 (free version)… quite old, but working fine for my needs. HA itself (core, OS, Supervisor) is all the way up to the most recent versions. Same for ESXi integration.
Going to Developers Tools/States everything is unavailable. Integration does not start at all:
Up to today morning it was working perfectly fine, so I link this to 2022.7 update… but might be wrong…
How is your hass installed? Container, virtenv, etc?
The issue seems to be related to this. Issue 43998: Increase security of TLS settings in 3.10 - Python tracker
Your version of esxi is really old and I don’t know for sure if it supports tls1.2
Can you go into advanced settings (in esxi ui) and search for ESXiVPsDisabledProtocols and show the output?
Well, perhaps it is time for unscheduled weekend work and finally upgrade to newer version… Anyhow, here is what I found in settings:
So it seems that tls 1.2 is supported and is not disabled… Just for curiosity I enabled later SSL v3, but this did not changed situation, exactly same error in the log file.
In my case HA is installed as VM on mentioned ESXi host.
For python 3.10+ you need TLS1.3
OK, than it means some extra work ahead of me… Especially that there is no stright upgrade path from 6.0 to 7.0 
Perhaps clean instal 
What about 6.5 release? I didn’t upgrade the core yet
Do you have a source for that? Per What’s New In Python 3.10 — Python 3.10.5 documentation TLS1.2 is now the minimum, no mention of TLS1.3 being a requirement.
Apologies, I was misinformed. Thanks.
You could test it by specifically disabling TLS1.0 and 1.1. Changing the value to sslv3,tlsv1,tlsv1.1 should force TLS1.2.
Otherwise, I would not jump from 6 > 7. That’s a big jump with potential hardware compatibility implications.
No change, same errors… Time to think about upgrade strategy
If not jumping to v7 (which would be the most futureproof at the moment) what is the minimum version requirement to restore compatibility? Would it be 6.5, 6.7?
No problem going for v7 as long as your hardware is compatible. But if you’re been running esxi 6 on the same hardware since its release, i would be cautious. If your hardware relies on old drivers, you might run into issues. Definitely check the HCL before you proceed. Otherwise, 6.7 should be fine.
I have just installed the esxi hacs integration but I have no idea how to configure the integration?
Where can I fill in the host IP, username and password?
