Hi,
I tried to connect to home connect, the smart home system of Bosch and more. I started the wizard and filled in some API details but did not finish the wizard. Tonight I wanted to get further on it but the wizard does not start again, if I add home connect in the (add integration) i directly goes to a website. Can anyone help me to completely restart the wizard and remove everything that has, i asume, has been saved in the home connect config?
By the way, home connect is added to my integrations, so basicly is hanging in between…?
Step 1, add home connect in HA
After clicking i’m going directly to this page (Step 2)
And if i go back to HA, i got this message Step 3)
To finish this step go to external website (which is not accessable)
I might have filled in the wrong API address? Anyone who got an idea how to fix this?
Have you found any solution, i have the exact same problem
what helped me, is starting the procedure from a remote connection, instead of local. I use nabu case remote ui, as portforwarding isn’t an option to me.
The rediret URI is: Link to OAuth2 Authorize Callback – My Home Assistant .
Been struggeling the past couple of days as well.
I’m sharing what I found tonight because I was going crazy with the same issues trying to get the Home Connect integration working. After I tried it the first time, the integration wouldn’t show up anywhere (except for search when trying to add it new), and it would skip the dialog where you enter all the token and client key info and only show the final “click this link to finish the install”.
I also tried accessing my install from outside my network as someone else explained and lost a good long time trying that - it also didn’t work.
But here’s what did:
Go to Settings → Devices & Services. In the top right corner, click the three-dot menu (it’s above the three-dash menu) and look for “Application Credentials”. Click it, and look for the Home Connect credentials you first put in and delete the entry altogether. This will allow the system to take you back to the very beginning and re-enter your credentials when you’re trying to install the Home Connect integration.
One other thing, this may or may not be an issue but I read somewhere the Home Connect is twitchy about capital letter in some places (especially email addresses). I don’t know if this is why things failed for me the first time but I made sure to choose a name both in the Home Connection Application creation and in the Home Assistant Integration that had no capital letters and no spaces. This worked without any issues the 2nd time once I had deleted the credentials as described above.
I just thought that since I found this post in my search for answers, others might, too. I wished the answer had been posted here and hope it might help someone else in the future.
