Amazon Echo

This “Hue Emulation” solution is working very well for me; currently with just “turn on / turn off” of ANY switch; but easily expanded to issue a command to any device (including dim, and set temperature via dim phrasing). Just no status responses.

It’s certainly a “hack” and requires a small server on your net (< $40 Raspberry Pi or Beagle Bone), and may eventually break; but by that time, there will be more integration choices. This one is excellent.
