@nikgru Same. 1.7.2138

@nikgru I just had them close to each other (~1 meter), had the lamp in "factory default"-settings (turn on/off the lamp 6 times) and activated discovery of generic zigbee-device in my Vera Plus.
It ended up as a light in my Vera and, as I said, I eventually managed to turn the lamp off using the vera controller but it wouldn't turn back on.

I recently bought Vera Plus controller and a "trådfri" lamp.

I managed to "successfully" pair the lamp and the Vera Plus controller. And I, once, managed to turn the light off.
I could not get it back on for some reason, but I am sure that someone with some backwards engineering skills can make it happen!
