Tradfri with HUSBZB-1

I see varying posts on this - can I use the Ikea Tradfri stuff without a Tradfri hub? I have the HUSBZB-1 z-wave/zigbee combo stick already working with other zigbee and z-wave devices.

It’s been on my list to do this for some time. Was also looking how to approach this and found some instructions here: Has anyone tried the Sengled LED bulb with the HUSBZB-1?
