I just used the raw command on seven installed FanLincs... bought since then end of 2012. Extended command worked on all 7. Would love to see this (on/off) in the Indigo FanLinc device itself if you ever get a wild hair. For now I just set it up as "contingent" action which I can select the fanlinc just prior to execution. 5 of my 7 fans, the LED's were brightly visible... cool effect, until I had a guest complain of the red light.
I know... I know you're busy, and yes... I appreciate all you do more than you know. Thanks
