I just wanted to say that I've been using the HBB wrappers and aliases with Alexa and it works quite well. Even thought HBB was built for Homebridge the devices are very generic and let you do a lot more with Alexa than just on/off/dim.
At first I was a little unexcited about how Alexa could only control "hue" lights but that's why I build HBB in the first place, so you could tell Homebridge about a "light" that really wasn't one. I'm now thinking of splitting the device capabilities from HBB and making that it's own plugin.
