Frontier Silicon Radio Binding - only one device possible?

Hi there

I am just exploring the Frontier Silicon Binding. I manually added a radio via Paper UI. The binding works excellent and with all of its features.

I would like to integrate a second Frontier Silicon Radio but via Paper UI there is no way adding one. Neither automatically nor manually.

Any body out there who could explain to add several FS-Radios easily? Or is there any alternate binding (I am using the current version incl. all updates of openHAB on a raspbi)

Thanks in advance
Justus
