DarkMute 0.1.8

Mute snapcast client playing on raspi3

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
