FOH Intercom

A networked communication system for theatre Front of House (FOH) and stage, using Raspberry Pi 4B, buttons, LEDs, and headsets.

Features

• 3-button interface with LED feedback for state communication:
  • Button 1: Stage free (green LED)
  • Button 2: Problem/Assistance needed (red LED)
  • Button 3: Custom/Other state (yellow LED)
• RGB LED for network/system status (e.g., connected, error, updating)
• (Planned) Push-to-talk headset audio for direct communication
• All devices networked via Power over Ethernet (PoE) for reliability and easy installation

Hardware

• Raspberry Pi 4B (with PoE HATs)
• 3x LED Push Buttons (for user input and feedback)
• 1x RGB LED (for system/network status)
• Headset with microphone (planned for future audio features)
• Ethernet switch and Fritzbox (for network connectivity)

See hardware/ for wiring diagrams and parts list.

Software

• Python 3 scripts for button/LED control and network communication
• Systemd service for automatic startup on boot
• Easy updates via git pull

See software/ for code and setup instructions.

Requirements

• Python 3.7 or higher
• See software/requirements.txt for required Python packages

Quick Start

1. Connect hardware as shown in the wiring diagrams in hardware/.
2. Clone this repository to your Raspberry Pi:

   git clone https://github.com/ProkopK/foh-intercom.git

3. Install Python dependencies:

   pip install -r requirements.txt

4. Set up environment variables
5. Set up the systemd service for auto-start.
6. Power up the device via PoE and test button/LED functionality.

Usage

• Press the buttons to communicate states between FOH and stage. LED feedback will indicate the current state.
• The RGB LED shows system/network status (e.g., green for connected, red for error).
