Control Hatch Baby Rest devices using Bluetooth LE

Hatch Baby Rest BLE API (.NET)

This .NET API allows programmatic control over the basic functions of the Hatch Baby Rest Smart Night Light, Sound Machine and OK-to-Wake, including control of Power, Color, Volume and Audio Track.

Requirements

• .NET Framework v4.6.1+
• Windows 10 Creators Update (OS Version 15063 or later) - to support non-pairing Bluetooth LE communication
• Windows 10 Compatible Bluetooth LE hardware (tested on Intel Dual Band Wireless-AC 7260 with integrated Bluetooth)

Installation

Install-Package m4rcus.HatchBaby.Rest

Usage

Examples in C#:

using m4rcus.HatchBaby.Rest;

Discovering devices

foreach (var rest in RestDevice.Discover().Result)
{
    using (rest) // dispose of the device when done with "using" or .Dispose()
    {
        // save rest.Name and rest.BluetoothAddress
        // for later use
        await rest.SetPower(true);
        await rest.SetVolume(60);
        await rest.SetAudioTrack(AudioTrack.TRACK_STREAM);
    }
}

Using devices via saved bluetooth address

// connect directly without discovery if address is known, ex "CBBABE52631F"
var bluetoothAddress = ulong.Parse("CBBABE52631F", System.Globalization.NumberStyles.HexNumber);
using (var rest = new RestDevice("MyHatchRest", bluetoothAddress))
{
    Console.WriteLine(rest.Data.Color);
    await rest.SetColor(Colors.Red);
    await Task.Delay(5000);
    await rest.SetPower(false);
}

Viewing debug output on console

static void Main(string[] args)
{
    // output debugging info to console
    Trace.Listeners.Add(new ConsoleTraceListener());
}

See the sample console app for more examples.

This library currently supports Power, Color, Volume and Audio Track. For other functionality (events, time), PRs are welcome!
