Installing Z-Wave dimmers in a new build, thought I'd give the Alexa API a spin together with Indigo!
Works quite well, though the recognition is iffy. I improved it a bit by using a word distance algorithm and including the names of all the possible devices, so if it hears "Counting Lights" instead of "Counter Lights", it would still be able to figure out that it's actually Counter Lights.
Even so - word choices are important. Some are either too awkward to say within the dictates (pun intended) of Alexa's required request/sentence structure. Yes, I have a set of lights called "Table" since "Pendants" or "Dining Table Lights" wasn't always 100% (even with the current distance algo).
The other thing is naming my app "Casa Mia". Why? Well, "home" "home-buddy", "home-something" all confused Echo and triggered its wemo/other supported home control stuff which I don't use (Echo would say something to the effect of "can't find device so-and-so in your device-list".
