AirPlay Relay Controller
IoT project that turns a Raspberry Pi into an AirPlay receiver with automatic GPIO relay control. Detects audio streaming and triggers amplifier power via relay with configurable delay.
AirPlay Relay Controller
Project Overview
Built a Dockerized IoT application that turns a Raspberry Pi into an AirPlay audio receiver with automatic amplifier power management. When an Apple device starts streaming audio, the system detects the AirPlay session and triggers a GPIO relay to power on connected amplifiers. When streaming stops, a configurable delay timer powers the amplifiers off automatically.
Technical Highlights
The system uses shairport-sync (v4.3.2) for AirPlay reception with ALSA audio output and SoX resampling for high-quality playback. A metadata pipe monitors playback state changes (pbeg/pend events) and a custom Bash script manages GPIO relay switching with debounce logic. The entire stack runs in a Docker container on BalenaOS, supporting Raspberry Pi 3 and 4 hardware. Configuration is fully environment-variable driven for GPIO pin assignment, active state polarity, turn-off delay, AirPlay device name, volume control, and audio backend selection.
Problem Solved
Eliminates the need to manually power amplifiers on and off in a whole-home or distributed audio setup. The relay controller acts as a bridge between consumer AirPlay devices and professional/consumer amplifier hardware.
