Python library to control Hatch Baby Rest devices

pip install pyhatchbabyrest==2.0.1


Hatch Baby Rest Python Bindings

This library will allow you to control a Hatch Baby Rest device (note, /not/ the Hatch Baby Rest+, which is Wi-Fi enabled) over BLE.


The pygatt backend was tested on a Raspberry Pi 3 Model B Rev 1.2, but should work on any Unix system that is compatible with the GATTToolBackend of pygatt.

The bleak (async) backend was tested on a 2019 MacBook Pro, but should work on any system that bleak is compatible with.


pip install pyhatchbabyrest


pygatt backend (synchronous)

In [1]: from pyhatchbabyrest import PyHatchBabyRest

In [2]: rest = PyHatchBabyRest()

In [3]: rest.power
Out[3]: False

In [4]: rest.power_on()

In [5]: rest.volume
Out[5]: 30

In [6]: rest.set_volume(10)

In [7]: rest.volume
Out[7]: 10

In [8]: rest.set_color(255, 0, 0)

In [9]: rest.color
Out[9]: (255, 0, 0)

In [10]: rest.set_brightness(100)

In [11]: rest.set_sound(

In [12]: rest.sound
Out[12]: < 2>

In [13]: rest.set_color(*PyHatchBabyRest.COLOR_GRADIENT)
In [14]: rest.connected
Out[14]: True

In [15]: rest.disconnect()

In [16]: rest.connected
Out[16]: False

bleak backend (async and a little more portable)

In [1]: from pyhatchbabyrest import PyHatchBabyRestAsync

In [2]: rest = PyHatchBabyRestAsync()

In [3]: import asyncio

In [4]: loop = asyncio.get_event_loop()

In [5]: r = loop.run_until_complete

In [6]: r(rest.power_on())

In [7]: r(rest.set_volume(100))

In [8]: r(rest.set_volume(10))

In [9]: r(rest.power_off())

In [10]: rest.sound
Out[10]: <PyHatchBabyRestSound.noise: 3>


Huge thanks to @Marcus-L for their repo at GitHub - Marcus-L/m4rcus.HatchBaby.Rest: Control Hatch Baby Rest devices using Bluetooth LE which did all the hard work of finding the right characteristics, commands, etc.
