Nuheat Integration fails with an authentication error

[DennisOtt-git-hub]

The problem

I had the Nuheat integration set up and working but when I did the last upgrade to my HA it failed to setup. I can log into the Nuheat website from my browser so I know the credentials and serial number are accurate. I deleted the integration and tried to reinstall but now I can't get passed the initial log in authentication configuration page.

Log entry:

2022-10-27 10:18:49.280 ERROR (MainThread) [homeassistant.components.nuheat] Failed to login to nuheat: HTTPSConnectionPool(host='www.mynuheat.com', port=443): Max retries exceeded with url: /api/authenticate/user (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x93989b68>: Failed to establish a new connection: [Errno -2] Name does not resolve'))

I am experiencing the same error. I have two NuHeat floors hence the double session entry. I’m going to guess that the underlying nuheat Python library is now out of date.

log below: ———

FWIW, I haven't been seeing these problems with either 2022.10.5 or 2022.11.1.

@DennisOtt-git-hub Are you still seeing this problem? The exception you cited appears to be logged by Home Assistant here from a call to api.authenticate() in python-nuheat, which in-turn tries to POST to https://www.mynuheat.com/api/authenticate/user.

When I search for "HTTPSConnection Failed to establish a new connection Name does not resolve", it looks like when this error happens in other projects, it's been either a problem with DNS or a mal-formed URL. In this case, the URL being used (https://www.mynuheat.com/api/authenticate/user) seems fine to me (and hasn't changed in python-nuheat lately). Maybe Nuheat was doing maintenanace at the time?

@Skyman64 The error you cited ("Failed to login to nuheat: Authentication error") is a bit different. This one also appears to be logged by Home Assistant here from a call to api.authenticate() in python-nuheat. However, in your case, instead of the exception coming from the POST to https://www.mynuheat.com/api/authenticate/user, it's actually raised a few lines later when it doesn't find a SessionId in the server response.

In both cases, I'm most inclined to believe this was a case of bad timing -- Nuheat server maintenance that happened to coincide with when you upgraded Home Assistant (and therefore needed to re-authenticate with Nuheat's servers).

@DennisOtt-git-hub If you agree with this assessment and are no longer seeing this problem, please close the issue. Otherwise, please let me know what other information you think might suggest a different root cause.
