Dark Mute

Dark Mute is python script that mutes snapcast client volume when it senses lights are off in the room.

It's written in Python 3 and requires a photoresistor-capacitor circuit connected to a Raspberry Pi running Snapcast.

Setup/Usage

As the pi user in its home directory:

• python3 -m venv darkmute-venv
• . darkmute-venv/bin/activate
• sudo python3 -m pip install DarkMute
• Test it: darkmute

Brightness thresholds are hard-coded for now, to change them see Developer Setup section.

To run this as a service, create a systemd service definition:

/etc/systemd/system/darkmute.service

[Unit]
Description=Dark Mute
After=snapclient.service

[Service]
ExecStart=/home/pi/darkmute-venv/bin/darkmute

User=pi

[Install]
WantedBy=multi-user.target

Developer Setup

• Clone this from gitlab
• Create and activate Python 3 virtual env
• pip install -e . to install dependencies
• Build the circuit, connected to GPIO Pin 7
• add user to gpio group /dev/gpiomem
