Command line Binary Sensor

The command_line binary sensor platform issues specific commands to get data.

To use your Command binary sensor in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: command_line
    command: cat /proc/sys/net/ipv4/ip_forward

Configuration variables:

  • command (Required): The action to take to get the value.
  • name (Optional): Let you overwrite the name of the device. By default name from the device is used.
  • device_class (Optional): The type/class of the sensor to set the icon in the frontend.
  • payload_on (Optional): The payload that represents enabled state. Default is “ON”.
  • payload_off (Optional): The payload that represents disabled state. Default is “OFF”.
  • value_template (Optional): Defines a template to extract a value from the payload.
  • scan_interval (Optional): Defines number of seconds for polling interval (defaults to 60 seconds).


In this section you find some real life examples of how to use this sensor.


Check the state of an SickRage instance.

# Example configuration.yaml entry
  - platform: command_line
    command: netstat -na | find "33322" | find /c "LISTENING" > nul && (echo "Running") || (echo "Not running")
    name: 'sickragerunning'
    device_class: moving
    payload_on: "Running"
    payload_off: "Not running"

Check RasPlex

Check if RasPlex is online.

  - platform: command_line
    command: 'ping -c 1 rasplex.local | grep "1 received" | wc -l'
    name: 'is_rasplex_online'
    device_class: connectivity
    payload_on: 1
    payload_off: 0

An alternative solution could look like this:

  - platform: command_line
    name: Printer
    command: ping -W 1 -c 1 > /dev/null 2>&1 && echo success || echo fail
    device_class: connectivity
    payload_on: "success"
    payload_off: "fail"

Consider to use the ping sensor as an alternative to the samples above.
