This app bridges all sms messages to matrix. For every (new) text conversation contact the bot will open a private 1:1 room and sends the incoming messages to that room. Any messages sent in that room by the matrix user will then be sent to the contact via SMS. As currently there is no end-to-end encryption implemented in this app, for privacy reasons it is preferable to use it with your own Matrix server. Your data-in-transit however will always be safe as they are encrypted using https over matrix -- provided the Matrix server is configured properly.

Snapcast is a Snapcast control client and player for Android. It uses the Snapcast JSON-RPC API to control your synchronous multi-room audio player. This App is not meant for productive use and will only run when you have a Snapserver installed in your local network. Snapcast is a multi-room client-server audio player, where all clients are time synchronized with the server to play perfectly synced audio. It’s not a standalone player, but an extension that turns your existing audio player into a Sonos-like multi-room solution. The server’s audio input is a named pipe /tmp/snapfifo. All data that is fed into this file will be send to the connected clients. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy, which can be configured to use a named pipe as audio output.
