As mentioned a while ago, I've been developing (on and off) a DIY Alexa Skill for Squeezebox integration and been using it successfully at home for a while now.

Anyway - it's now improved and open-sourced on Github:

This is a separate approach from Meep's excellent work on hab-tunes (we have discussed some common areas though). Currently it's definitely techies only I'm afraid (no actual coding but you'll need to know a bit of Linux, Networking, SSL... and have Amazon developer accounts). The pay-off is it's optimised for speed and security I guess.

PS - I'm not on the forums much, so if you want to get in touch best to do it via Github (or Twitter)
