Colorado4Wheeler's HomeKit Bridge plugin is in open beta, and it uses a new version of homebridge-indigo that is custom tailored to work with HomeKit Bridge and is installed seamlessly with the plugin. It makes setup super simple, and it's so good, I've switched my house over to use HomeKit Bridge instead of a separate homebridge-indigo server.
Even though it's still in beta, I strongly recommend using it. Find out more here: viewforum.php?f=201
