FFmpeg Noise

The ffmpeg integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to use any video or audio feed with FFmpeg for various sensors in Home Assistant.

Note

If the ffmpeg process is broken, the sensor will be unavailable. To control the FFmpeg process of sensor, use the ffmpeg.start, ffmpeg.stop, and ffmpeg.restart actions.

Configuration

To add FFmpeg with noise detection to your installation, add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file. After changing the configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file, restart Home Assistant to apply the changes. The integration is now shown on the integrations page under Settings > Devices & services. Its entities are listed on the integration card itself and on the Entities tab.

# Example configuration.yaml entry

Configuration Variables

Looking for your configuration file?
input string Required

An FFmpeg-compatible input file, stream, or feed.

name string (Optional)

Override the name of your camera.

initial_state boolean (Optional, default: true)

Start FFmpeg with Home Assistant.

peak integer (Optional, default: -30)

The threshold of detecting noise, in dB. 0 is very loud and -100 is low.

duration integer (Optional, default: 1)

How long the noise needs to be over the peak to trigger the state.

reset integer (Optional, default: 20)

The time to reset the state after no new noise is over the peak.

extra_arguments string (Optional)

Extra options to pass to ffmpeg, like audio frequency filtering.

output string (Optional)

Allows you to send the audio output of this sensor to an Icecast server or other FFmpeg-supported output, e.g., to stream with Sonos after a state is triggered.

To experiment with values:

ffmpeg -i YOUR_INPUT -vn -filter:a silencedetect=n=-30dB:d=1 -f null -

Troubleshooting

Unresponsive after a while

If the noise sensor becomes unresponsive, make sure you have extra_arguments: -nostats in the configuration.
