Glad most of it worked out, I missed your post earlier.
Those Wink sensors should work, I think they were just rebranded Dome sensors? Try to factory reset them, and bring them to the hub (or the hub to them) and see if they will include.
What I do think you might be missing is enough Zwave devices in your mesh to give everything a strong signals. These can be purpose built Zwave repeaters, or line powered devices like light switches. How to Build Your Z-Wave Mesh
You also should run a Zwave repair now that you have some devices on there. This is true any time you add new Zwave devices. This is different than what you had to do for Wink, but not a big deal to do.
