The Wink hub is still new to the market, and has lots of potential, but needs work to get there. Wink hub was very easy to setup and use, connected right away to GE Link Bulbs. The mobile application is sufficient for the capabilities the hub currently provides. The hardware of the unit supports many different protocols, Zwave, Zigbee, Bluetooth, Wifi, and others. Unfortunately many of these protocols are unable to be utilized with the current state of hub software. Support for the Hub is provided via email only, and currently takes weeks to get a response, which is typically "Not supported at this time". Devices that are not Wink certified are not guaranteed to work, and from my experience will connect to the hub, and sometimes partially work, but not fully. There is no community for support for this product, another downside compared to competing products. Overall this unit is extremely inexpensive compared to other options, and likewise limited. If you are simply looking for basic home automation, particulary GE Link Lighting, the unit works well.
