Hass.io + Deconz to emulate a hue bridge

Hey guys :wink:

a very lovely day to all of you!

I have a raspberry running Hass.io with a Conbee2 connected. So far, everything works fine.
Now, I want to totally replace my hue bridge an connect my TV and Hue Sync (pc app) to the conbee2/deconz.

Unfortunately neither the TV nor the Hue Sync app finds a bridge.
In deconz, I activated the app connection setting, but nothing happened.

Do I have to configure specific ports in deconz or do anything else additionally in HA config file?

Thanks a lot!
