500 Internal Server Error about homeassistant-homeconnect HOT 20 CLOSED

It is taken from hass.config.api.base_url. Can you please try adding the "correct" host name/IP in your HA config like

http:
  base_url: https://HOST:PORT 

from homeassistant-homeconnect.

@immert20 Sounds like you need to set your base_url parameter of the http component (and prefixing it with https)

from homeassistant-homeconnect.

Can you please delete the .homeconnect-token-cache.json in your config directory and try again? It might be an invalid token from a previous try.

from homeassistant-homeconnect.

Oh, I see.

Can you try if it works when you add

import os
os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'

at the beginning of custom_components/homeconnect/__init__.py?

from homeassistant-homeconnect.

Same also after the import os

from homeassistant-homeconnect.

I just checked on my own HA instance that is also behind an nginx proxy and it worked. Calling the /api/homeconnect endpoint directly, I also got a 500, but this is normal (after the login redirect, it is called with additional parameters).

Can you please double check that you have https://hasstest.domain.com/api/homeconnect listed as one of the valid Redirect URIs in your Home Connect app's settings? Perhaps you accidentally put http there?

from homeassistant-homeconnect.

Thanks very much, using

import os
os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'

gets me 1 step closer, a blank file called homeconnect was downloaded (which I can assume is safe to ignore, same as with the Spotify component), and the .homeconnect-token-cache file was created correctly on the server.

Once connected I don't get a success message, the configuration popup turns blank and I'm then unable to discover any devices. I suspect that this is a different unrelated issue, but not sure what yet, will do some more digging then open up another issue if necessary

from homeassistant-homeconnect.

OK - that means that the authentication indeed succeeded (I also have the problem with the blank window and sometimes downloaded file, not sure how to get rid of it. Indeed I copied most of the code for that from the Spotify component).

Concerning the absence of devices, I assume you have added them to your Home Connect account (using the Android app), right? Are there any errors in the HA log?

from homeassistant-homeconnect.

Where do you read out the URL for Authorising? Mine url show my internal IP address.. When I edit the URL for authorise I can login with my HomeConnect credentials en get the 500 error. But when I click on Successful authorised nothing happen..

from homeassistant-homeconnect.

@immert20, so you are being shown the Home Connect login screen? This is good, because it means the redirect URI is being accepted. Then when you are done authorizing, you are getting a 500 server error, do I understand correctly?

If so, can you please check if there is any error showing in your home-assistant.log?

from homeassistant-homeconnect.

@DavidMStraub Yes I get that, but only after edit the url manually.. because there is an internal ip filled in. I don't know where that $vars is coming from.

from homeassistant-homeconnect.

Yes it works!! But I tried to switch on my Coffee machine from HASS, but it won't turn on

from homeassistant-homeconnect.

Indeed, the power on/off switches don't work for me either (also using raw API calls) and I don't know why.

Are you able to brew coffee though, once switched on manually and acticating remote start?

from homeassistant-homeconnect.

Hmm that's weird. I will check that tonight!

from homeassistant-homeconnect.

Same issue.
Behind nginx reverse proxy.

Items shown in homeassistant but disappear at first restart

from homeassistant-homeconnect.

same issue here.
HA 101
no reverse proxy
base url set (https)

I also deleted homeconnect token cache and retried but no improvement.

from homeassistant-homeconnect.

Any error in the log?

from homeassistant-homeconnect.

By the way I received an e-mail from the Home Connect Developer Program yesterday mentioning that they have some problems with the API due to increased traffice after relaunching their mobile app. So it might just be that the server was down.

from homeassistant-homeconnect.

It seems to work now. Honestly speaking, I don't know why.

from homeassistant-homeconnect.

Hello everyone,
I seem to have the same problem. I am trying to install Home Connect and I used
http://192.168.0.224:8123/auth/external/callback
as Redirect URI.
I can login when I hit "Open Website" and then when I confirm that I want to grant access to everything, I get the error
500 Internal Server Error Server got itself in trouble

Any idea what could be causing this or what to try to fix it?
