I was browsing through z-wavealliance and saw that Leviton has some new Z-Wave switches registered as of 9/7. They look to be pretty robust as far as capabilities and configuration parameters. What I am looking forward to most:
Instant Status, configurable dim level and rate, min/max light level, locator LED status, and LED dim level indicator timeout.
DZ6HD - 600W Dimmer
DZ1KD - 1000W Dimmer
Home Depot has the DZ6HD listed for listed for $49.97 but is not available yet.
