Hey, this is an old thread but I just found it and I just wanted to mention that I’m also working on a Wink binding relying on the Wink API (i.e. doesn’t require to root the hub), I’m discussing this in Offering to implement the Wink Hub 2 bindings
The code lives here: https://github.com/sebmarchand/openhab2-addons/tree/master/addons/binding/org.openhab.binding.wink (not really documented right now, I’m working on it!)
