Have a RaspberryPI linking my LightwaveRF to SmartThings so decided to connect it to my amplifier so that I could get voice notifications over my speakers when events happen in my house. The node server uses the amazon Ivona service, which is really good (probably the best TTS service at the moment) and free on beta!
Re-Coded the Sonos weather SmartApp to send to the node server, allowing you to set and play whatever custom messages you want based on system events.
Here is the GIT repo,
Here is a quick demo video (it’s 1 in the morning!)
And here is a video with how to set it up,
