InfinityX

Overview

This project integrates an ESP32 microcontroller directly inside an Infinity Bluetooth speaker to bring it into Home Assistant. By wiring the ESP32 directly to the speaker's physical Play/Pause, Power, and Volume buttons, the microcontroller mimics physical button presses. Power for the ESP32 is drawn directly from the Bluetooth speaker's internal circuitry, making it a fully self-contained smart integration.

Features and Integration

• Direct Hardware Integration: ESP32 mimics physical button presses using GPIO outputs.
• Self-Powered: Draws power directly from the speaker.
• Power Control: Short and Long Press mimicking.
• Playback and Volume Control: Dedicated play/pause and volume controls mapped through GPIO.
• Status Sensor: Reads speaker power state to report back to Home Assistant dynamically.

Hardware Configuration

Outputs (Active Low, Open Drain) connect to corresponding button pads:

• PWR (Power button): GPIO16
• PP (Play/Pause button): GPIO17
• VOLU (Volume + button): GPIO18
• VOLD (Volume - button): GPIO19

The speaker power status is read via GPIO34 (Input), connected to a point on the PCB that goes high when the speaker is on.
