Not sure if this is what you're looking for, but it works with abode and it's a dimmer.

I have it programmed to turn on when an alarm is triggered. Pretty sure it can't flash though.

I have been using Cree, Ge Link, Sylvania for a about two years without any issues. Two weeks ago I decided to buy a zwave bulb to see if it would work, it works without any issues.
