When I got my Amazon Echo, it seemed like a natural fit into my home automation setup, allowing me to add voice control and speech output.

There’s just enough already built in that not being able to do this is frustrating.

Here’s what I did to get it to work. My solution is general enough that it can be easily tweaked to work with many different technologies as long as you’ve got some kind of API available.Continue reading
