For those unfamiliar, If This Then That (IFTTT)
is a service that lets you hook two internet services together, with the first acting as a trigger and the second as a destination. For instance, you can say IF a new Instagram photo is posted in a certain area, THEN save it to my dropbox folder.
I've written an app that (with some work) hooks a Sonos system to IFTTT. So you can do things like IF someone tweets with a hashtag, THEN speak the tweet through my Sonos, or IF I arrive home, THEN play a specific Sonos Favorite.
It's pretty cool to ponder the neat things you can do with the scores of channels that IFTTT offers.
Check it out, and let me know if you have any questions. And certainly let me know how you end up using it.
