This plugin allows control of Indigo controlled devices (actual devices, action groups, virtual devices, etc) from any client device or application that knows how to control LIFX devices.
The motivation for this plugin was that I couldn't find any way to get my Logitech Harmony Hub to control my Lutron lights. It has a fairly limited number of Home Automation devices it knows how to talk to, and Lutron's not on the list.

But, LIFX bulbs are, and there's a published protocol for talking to the bulbs. Well, the protocol for writing a client to control the actual LIFX bulbs is published. There's some unpublished variations required to emulate a bulbs so that existing clients (like the Harmony Hub) will talk to you. I've got it working at least well enough for people to try it.
Setup is a bit like the Alexa-Hue bridge in that you select the devices you want to publish through the bridge, including alias names. Not absolutely necessary for the bridge since you won't be trying to speak the names, but still useful since you'll be seeing the device names in the Harmony app.
Lots of things don't work yet. The built-in update check only runs on plugin startup. Switch devices should go on and off. Dimmer devices will only turn on and off. Setting dim level (brightness) is coming.
