ESPHome Configuration Files

This repository contains a collection of ESPHome configuration files for various IoT devices and components of mine. While the main focus for many users will be the OpenHaystack component, this repository also includes configurations for a variety of other devices and sensors.

OpenHaystack Component

The OpenHaystack component allows ESP32 devices to act as AirTags-compatible trackers, making them visible in Apple's Find My network.

Usage

To use the OpenHaystack component in your project:

1. Include it as an external component in your YAML configuration:

external_components:
  - source:
      type: git
      url: https://github.com/barrenechea/esphome-config-files
      ref: main
    components: [openhaystack]

2. Add the OpenHaystack configuration to your YAML:

openhaystack:
  key: !secret openhaystack_key

3. Make sure to add your base64 advertisement key in your secrets.yaml file.

For a complete example, check openhaystack-demo.yaml or openhaystack-demo-s3.yaml.

Common Configuration

The repository uses a modular approach with common configurations stored in the common/ directory:

• common/board/ - Board-specific configurations
• common/core/ - Core functionality (Wi-Fi, API, OTA, logging)
• common/devices/ - Device-specific configurations
• common/time/ - Time synchronization
