2n / Helios Integration

Hi there, new HA user here, since yesterday.

Am struggling to get the custom integration for my doorphone working.(found here).

I’m confident that I’ve followed the instructions :slight_smile: but cannot get HA to authenticate when trying to add the device. I can successfully execute commands via the 2n API via a browser, however, when trying to login via the HA pop-up, I’m greeted with “Unknown error”

Any suggestions to allow me to at least go from Unknown to Known?

Cheers.
