Should be supported indeed:
Can you see the device information at advanced settings of that device? Cause I see this one should be supported: Go BT (LCT026), maybe you have another ID, then it needs to be added.
But reading your post it’s seems like a zigbee pairing issue, which is athom responsibility, not app related. But I’m not sure.
I think @johan_bendz can help you. This is btw the right topic where the question should have been asked: Philips Hue Zigbee
