Shelly1 cannot be connected

I am unfortunately not able to connect my shelly1 to homebridge.

It is connected to the local network, can be accessed via shelly app and directly with http:///shelly, too. Thought it would be easier to plug & play with it. Wifi devices are allowed to talk to eachother. My 2 vacuum cleaners could be found as well, plus a TP Link device.
