Omnilink Binding 3.2.0 not Auto discovering

I have just started a fresh Openhab 3.2.0 installation and after setting up my Omni Controller I thought it should ‘auto discover’ my devices. The controller is online & have setup ‘Security Mode’ which changes when I Arm/disarm so it is communicating with my controller.
Am I misunderstanding my devices should be auto discovered? It worked great using 2.5.0. on my old setup.
Thanks
Scott

Finally found the ‘Scan’ button
