I have been using homebridge for a while "the hard way". I got some new devices and I saw this new plugin was available so I finally decided to give it a try. The automatic migration was very easy, and I only had trouble with a few devices like my Nests and some virtual devices. I recreated those and things are working flawlessly. Thanks so much, it is much easier to maintain the system this way!
Last thing I did was creating Action Groups/Virtual devices for AV controls through Harmony Hubs. They are working great too! I have been running HomeKit and Alexa parallel in my house, but with this I believe Alexa will be out-the-door very soon. Thanks again.
