I've installed one Z-Wave dimmer (Vizia RF+) and one lamp module (Intermatic) and I'm a bit disappointed with Z-Wave. The lamp module is about 6 feet from the PIM (VRC0P) and the dimmer another 10 feet away. The dimmer misses a command from time to time.
But the most annoying thing is to discover that with HA software, the Z-Wave dimmer ramp rate can't be chosen on the fly, only the ramp rate selected in the dimmer is used. It's apparently part of the Z-Wave protocol.
I then noticed that the driver for UPB in the software allowed for all of the normal things you would expect, but also allows for the selection of ramp rate when turning a device on or off. I would have expected this with any of the new technologies.
So, I'm taking another look at UPB. I had wanted off the power line, and don't want to get into a bunch of filters, bridges, repeaters and other patches like X-10 requires.
I would love to hear from anyone who has physically compared Z-Wave to UPB and what their experiences are. We certainly don't need another "which is better thread", I'm mostly interested in hearing from someone who tried Z-Wave and found they like UPB better. That's the dilemma I'm in.
My house isn't large, maybe 1500 sq feet and I won't have more than a dozen or so devices. My software is Elve. My house is a direct feed off the transformer on the pole.
