Snoo Buttons

Why

The Snoo bassinet only has a start button, everything else is controlled via an app. If someone is coming over to help and needs to control the bassinet, you either need to share credentials for the app or be present to manipulate the Snoo.

With a Raspberry Pi and some buttons, we can solve this.

Configuration

Required parts

• 4 buttons
• Breadboard
• Patch wires
• LED
• 330 Ohm resistor

Wiring the breaboard

• Wire a common ground on the breadboard to the RPi ground
• Wire LED to common ground and to resistor, then connecting the resistor to a GPIO pin. Note the pin
• Wire each button to the common ground and then to a GPIO bin. Note the pins

Setting up the library

Tested on a Raspberry Pi with Raspian, but should work elsewhere too.

• Clone with: git clone https://github.com/nnewman/snoo_buttons.git and cd snoo_buttons
• Create .snoo_credentials.json with a json of your "username" and "password". This is used once to generate a token.
• Run cp .env.template .env and fill with the pin numbers for your 4 buttons & LED
• Run pip3 install requirements.txt to install Python requirements
• Edit /etc/rc.local and run as your Pi user like so:
  • su pi_user -c 'python3 /home/pi_user/snoo_buttons/main.py &'
• Create log file location mkdir logs
• Reboot & it should run! (verify by running ps aux | grep snoo after boot and looking for the invocation)

Contributing

To run tests, first run pip3 install -r requirements_test.txt then use TEST=1 python3 -m pytest -W ignore::gpiozero.PinFactoryFallback -W ignore::DeprecationWarning --pdb.
