This is probably a stupid noob question but I have searched pretty hard for an answer and haven't found it. I feel like I am missing something obvious.
Suppose I want to write a home automation controller, something that (for example) turns lights on and off based on a schedule or other conditions. In that case, I want to utilize the Smart Home devices. In essence I want to issue the "Alexa, turn xxx on" directive rather than respond to it.
