Home connect stops working after a few days

[seaniedan]

After a few days of working fine, I get:

The only workaround I have found is to continually restart home assistant.

[DavidMStraub]

This means the integration cannot connect to the API server. Most likely an issue with the API server or your network.

[seaniedan]

Thank you for the reply. No other connection issues with other integrations on homeassistant, and the “home connect” continues to function and report the dishwasher program time.

When I restart the home assistant, the dishwasher reports to homeassistant again. But after a few days I get this error.

[tpulatha]

The thing with this issue is: even if it’s a connection issue. Shouldn’t this be handled gracefully and retried after say 5
Minutes? (Actually I would recommend 1s, 10s 60s 5m 30m and then 60m intervals)

[seaniedan]

In case it's useful, here's the latest logs from a home connect integration on Home Assistant that stopped working. It might be chance, but seems to happen ifthe door is opened during the program.

Does anyone have a hint for me? Everything else on my network e.g. Home Assistant is working fine reading URLs from other integrations.

[seaniedan]

Still restarting HA because this integration fails with

  File "/usr/local/lib/python3.8/site-packages/oauthlib/oauth2/rfc6749/clients/base.py", line 198, in add_token
    raise TokenExpiredError()

I suspect the code needs to refresh the token, as per this issue - token not renewing #116 - lots of examples here of how to fix, if anyone has the ability/if David is accepting pull requests:
https://www.programcreek.com/python/example/105352/oauthlib.oauth2.TokenExpiredError

[dree007]

Similar issues here. Seems to only work occasionally at best.

Even when I now restart HA I directly receive an error regarding token expiration. No correct status is being delivered to my HA.

[DavidMStraub]

As stated in the other issue: token refresh is handled by Home Assistant core, so this repository is the wrong place to report issues with it, unless you have a reason to expect that something specific to this beta version is causing the issue.

I'm still not closing this issue because the graceful reconnects suggested above would be a useful improvement. But I don't expect to have time working on it.

[coinish]

Do you know where I could report this on the HA side? Is it the same as this issue ?

[DavidMStraub]

No, looks like a different issue. Not sure what you mean be "where you could report it", as an issue obviously...

[coinish]

I’m not sure how to report it. You say “it’s not an issue with my software, it’s home assistant core”. I just don’t know where to begin. Is there any chance you could create the correct issue with them and I could follow it up? All I know is that my dishwasher is saying “program ready to start”, and I’m getting lots of errors about tokens.

[scstraus]

I'm having this problem too.
