Cync Lights Custom Integration (Forked) Not Finding My Wifi Bulbs and switches

[adamfluegge]

I am very new to Home Assistant, but not to smart homes. I have about 20 Cync bulbs and 4 switches. I really want to connect them to my HAOS. I followed the installation instructions, I find the Integration, just fine. When it askes for login and 2FA I get the email with the code and type it in. I get the following error: "Invalid or unsupported Cync configuration, please ensure there is at least one WiFi connected Cync device in your Home(s)".

I am at a loss, I am positive all my lights are working, connected to wifi. But it is supposedly not finding the bulbs? If there is a fix for this I would be eternally grateful.
