Calex Variotone lightbulb - how to controll it on zigbee?


I’m incredibly new to openhab and zigbee but after installation I have some challenges with my first device and kinly ask some guideance, please. I run openhab 2.3.0 on a Pine64 and have a QIVICON USB dongle which uses cp210x driver and looks Telegesis in the logs. Dongle is reported online in UI and it discovers zigbee devices so I assume it works properly. Also I’ve tried to add my calex variotone lightbulb what appears with the following channel: zigbee:device:040013E8:00158d00024f6a44:00158D00024F6A44_1_switch_level
This channel type is not amongst the supported channel types @ - what shall I do in this case?

I have tried to define it in the default.items this way but controlling the bulb doesn’t work from the UI:
Switch My_First_Switch “lamp switch” {channel=“zigbee:device:040013E8:00158d00024f6a44:00158D00024F6A44_1_switch_level”}

  • OS: Linux Pine64-longsleep
  • Java Runtime Environment: (Zulu Embedded (build 1.8.0_112-b31)

Thank you in advance for any constructive comment
Kind Regards
