Official Alexa Smart Home Skill for openHAB 2

Regarding Groups In Alexa App
It seems like Smart Home Groups are enabled in the Alexa App. You can create a group and name it(e.g. “Kitchen”) and then selected the echo that’s in that area and the devices in that area. Then, In theory, I should be able to say “Turn off the lights” when I’m in the kitchen.

It doesn’t work. Alexa responds: “Sorry, I didn’t find lights”

Has anyone gotten this to work yet? Is the verbal command correct?
