Just picked up the news over in the RA2 forum:

What’s New Brochure

Coming end of 2016: the Wireless ELV+ dimmer for Caséta. Mirrors the look and function of the Pico 5-button remote, including preset button.

No word about any other new functionality like adjustable fade rate or remembering previous "on" level, but the preset button somewhat takes care of this one.

  • Works with all load types
  • 500W INC/HAL/ELV
  • 400W MLV
  • 250W LED
  • Has a “Favorite” button (matches the Pico® remote control)
  • Works with the Pico for 3-way and multi-location applications
  • Neutral required
