Is it possible to connect Mathematica to Amazon Alexa products, so you could -- for example -- make a queries like
amazonAlexa["turn off my lights"]
amazonAlexa["set 10 minute timer"]
?
Yes, see this WTC-2015 presentation by Todd Gayley “Commanding the Wolfram Cloud” on YouTube.
Here you can find the notebook: "Commanding the Wolfram Cloud" at library.wolfram.com.
