You are right, the NevoConnect and NevoQ50 talk over Z-wave. The cool thing is that there are no settings to mess with or routers to setup; VERY easy stuff.

I actually had pretty good luck with my NevoSLs, but I'll admit it was a much more involved process to get it working rock solid.

The NevoQ50/NevoConnect pair are simply awesome; very reliable and very easy to setup and plus you have a ton of new features with the NevoConnect that weren't found on the good ol' NevoLink.
