Hatch Rest – Home Assistant Integration

This is a custom Home Assistant integration for controlling the Hatch Rest (1st-generation) nightlight and sound machine over Bluetooth Low Energy (BLE).

It provides a fully asynchronous, locally-controlled interface using a rewritten BLE API based on — and with gratitude to — the original work by kjoconnor in the pyhatchbabyrest project.

✨ Features

• Local BLE control — no cloud required
• Three (3) entities exposed:
  • Light (RGB + brightness)
  • Switch (main power)
  • Media Player (sounds + volume)

📦 Installation

HACS

1. Add this repository as a Custom Repository (HACS → Integrations → Custom Repositories)
2. Search for Hatch Rest
3. Install → Restart Home Assistant

🔍 Adding the Device

1. Go to Settings → Devices & Services → Add Integration
2. Search for Hatch Rest
3. Choose your discovered device from the list
4. Confirm the Bluetooth address
5. Done!

🧩 Supported Entities

🔌 Switch

• Master on/off power state of the device

🟡 Light

🔊 Media Player

📡 Bluetooth Requirements

Because the Hatch Rest is a BLE device:

• A compatible Home Assistant Bluetooth controller is required

This integration uses BLE connections aggressively but cleanly:

• Queues operations
• Avoids simultaneous connects
• Disconnects when idle
• Automatically retries on common BLE failures
