core can't add devolo Giga Bridge - wrong password, but it's correct direct on device

The problem

I have two devolo Giga Bridges. In the past I saw them configured in HA. But since an update (core) the device says "wrong password". But when I open the device via IP I can login with that password. I also tried to delete the integration, reboot HA, add the integration again.

What version of Home Assistant Core has the issue?

core-2024.10.1

What was the last working version of Home Assistant Core?

core-2024.10.1

What type of installation are you running?

Home Assistant OS

Integration causing the issue

devolo_home_network

Anything in the logs that might be useful for us?

No response

Additional information

right after adding integration I get this error even before I enter the password. Is the password somewhere stored?

Sometimes I get Der Konfigurationsfluss konnte nicht geladen werden: {"message":"Invalid flow specified"}

Hi @TylonHH , could you please tell me, which FW version your devices have? As I don't have Giga Bridges at hand, I might need to contact my friends at devolo to find a solution.

Oct 10 '24 13:10 Shutgun

Sure

7.12.9.142 (2023-05-02)

Hi @TylonHH , we digged a little into this issue and have more questions.

First, it seems that the inavlid flow error happens when a automatic discovery happens while you configure the integration manually. Can you confirm, that you tried to configure it manually by entering the IP?

Does your setup contain more than one network interface? We saw issues in that case, that we still need to understand deeper.

But the good news is, that Gigabridge basically works with Home Assistant under certain conditions. So now we need to understand the remaining issues, that sould be independend from the Gigabridge but effect all devolo Home Network devices.

I have the same issue. Deleting the device and adding it manually via IP does not change anything. First, success is reported. Then it complains regarding wrong password as before. HA runs on a RaspberryPi with one LAN and one WLAN interface. The WLAN interface is not enabled/connected.

Oct 17 '24 06:10 kwidany

But that might be correct due to how the devices work. If there is a device password, HA cannot know until it queries endpoints that are protected. So the integration is set up and then a reauth flow is triggered as soon as e.g. the switch platform is loaded. If you follow that and give it the correct password, the integration will work.

Or are we not talking about the initial adding process?

Oct 17 '24 07:10 Shutgun

ok let's get some step back. You're right that technically this integration works with HA, because it did in the past (since?).

A devolo Giga Bridge makes only sense with two devices.

So I deleted all (two) devices to document my steps.

Integration "devolo Home Network" is added
integration automaticaly finds two devices
I click on config and confirm that
success
immediatlay there shows up an error und discovered and here this is within the integration, note: until now I never typed a password, and the error says its wrong (confused) so I click on congig new and enter the correct passwort, wich works direct on the device when opening it via IP Success? Nope

Same with adding by IP-adress

So I enabled Debug Logging Pop Up with Der Konfigurationsfluss konnte nicht geladen werden: {"message":"Invalid flow specified"} No Chance to enter the passwort after some deleting and readding with debugging I managed to get this

Is devolo-491 the local or the remote device like in: Is it GigaBridge (2) or GigaBridge (1) in your picture? And if it is the remote device: does the local device behave the same?

Oct 24 '24 13:10 Shutgun

Hi @TylonHH , I had also issues with integrating the GigaBridge into Home Assistant. Using the WebUI of the device to enter the password again (old password and new password can be the same), fixed it for me. Seems to trigger some internal processes.

Oct 30 '24 08:10 bong1991

I just had the same issue, and can confirm that what @bong1991 wrote worked also for me! :)

Nov 12 '24 15:11 reinob

Nice, so let me add that to the documentation, so that everybody is aware of that workaround until devolo might fix it.

Nov 13 '24 11:11 Shutgun

Confirmed

"Reset" the password within the devolo device via WebUI (to the same password) works.

Thanks to everybody and @bong1991
