Looking for an app that would allow me to set a message from my Android phone and have it displayed on my Chromecast w/GoogleTV equipped TV. Something so I can leave my family a quick "I've gone for a walk" note.
Most of the apps I've found are part of larger systems for corporate settings, etc.
You can just add a small speaker with Google in it, then use the "announce" functiion. Don't think this will work with aTV though.
