I could have sworn the Vera team at the last CES were showing a Zigbee controller. I'm hoping it will be available as an add-on for Vera...
I've seen a video of that demo but can't find it at this moment.
I was told by a Vera Rep at CES 2014 that Vera would support Zigbee "by the fall of this year."
(He also said UI7 would be released in April

).
No new Vera hardware is expected this year, he said.
Lowes Iris also had a room displaying tons of new products like this valve, including dog doors, swimming pool sensors and sensors to measure whether your plants need watering. All Zigbee, I assume.
