Control Your SONOS with Arduino and NODE-RED

Things used in this project

Hardware components

Arduino Nano 33 IoT

Raspberry Pi 3 Model B

Tactile Switch, Top Actuated

Jumper wires (generic)

Story

My first solution to control my SONOS system was Arduino and IFTTT.

After IFTTT is no longer free, I searched for an alternative. NODE-RED is a big tool to wire online-services, hardware etc. together. It has has lots of features and is easy to install on a Raspberry Pi. There are also extensions (palettes) for SONOS.

The only difficult part was to get the HTTP-POSTs from ARDUINO to NODE-RED, but with a simple http-endpoint node the job was done quickly.
