core Overkiz (local API) fails to connect when using the IP address of the box instead of its hostname

The problem

The recommended workaround for https://github.com/home-assistant/core/issues/108595 is to use the IP address of the Tahoma switch instead of its hostname.

However, when trying to do so, I'm faced with an "Unknown Error"

even tho when I use the same username and password with the hostname, it connects successfully.

I'm also experiencing this issue, but I cannot use the hostname to connect to the TaHoma Switch due to my specific network setup. I would appreciate any help on this!

I had the same problem, but I edited my /etc/hosts file including the proper IP/name pair (i.e. XXX.XXX.XXX.XXX gateway-xxxx-xxxx-xxxx.local ). Then, I used the name in the configuration wizard, which worked without a problem.

@mathieudutour do you still face these issues?

Not anymore but I can't remember what I did to make it work sorry. I think I reinstalled the integration from scratch and that time it worked
