Error while adding a new (first) WallBox

[JoostvdB94]

Following the HACS installation instructions, I get the following error:

Unexpected error creating device
Traceback (most recent call last):

KeyError: 'properties'

As this seems like an technical error, this seems like a bug.
In any authentication case I would expect a nice user friendly error specifying that the credentials were not correct.

I have the same error, also when adding the integration for the first time. I tried a couple of times so I'm certain that the credentials are correct (they work in ACE Service Installer and MyEve) so it must be something in the integration itself.

[pyrocumulus]

I figured it out. The credentials were in fact, not correct. The username should just be 'admin' not the ID of the charger itself (which is what I was using).

I agree with the fact that the error message could be more helpful though.

[leeyuentuen]

my bad, i'll take a look on wrong authentication to get a better error message

[JoostvdB94]

I can now see a better log message in the logs.
It looks like the port 443 cannot be accessed. Is it possible to disable TLS and connect on a non-encrypted port?

[leeyuentuen]

i think you are using the fork of mine? can you open the issue on my fork (to get better view which version)
https://github.com/leeyuentuen/alfen_wallbox/issues

could it be the same issue here: leeyuentuen#75
with the discussion here leeyuentuen#73
over firmware lower than v5 without authentication?

Looks like I am running into the same issue here.
I had the wallbox connected to HA with your custom integration. Everything was running great. After changing the hardware and moving from container based HA to HAOS the integration did not work anymore.
I deleted it and reinstalled it.

Now I run into the problem of "Unexpected error creating device."
Any idea what I am doing wrong?

HAOS Version: 2023.10.5
Supervisor 2023.11.0
Wallbox Alfen Eve Single Pro
Firmware: 6.5.0.-4217 (Was 6.1 before, same Problem)
Dynamic "Lastmanagement" set protocol on Energy Management System, Mode "Steckdose" (Plug)

Wallbox is accessible with Service Installer and MyEve app.

I also checked the right login credentials

• ip address with http:// and without
• "admin" and my login name for service installer (seen the thread for this, admin is right)
• password works in myeve app and in service installer

I have exactly the same issue - HA fully up to date, I can login normally via app and ACE Service Installer

This error originated from a custom integration.

I did not manage to get it working. Had to delete the custom repo. Afterwards I installed this version: https://github.com/leeyuentuen/alfen_wallbox
Works now.
