The command 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
binary_sensor:
  platform: command_line
  command: cat /proc/sys/net/ipv4/ip_forward
  name: 'IP4 forwarding'
  sensor_class: opening
  payload_on: "1"
  payload_off: "0"
  value_template: '{% raw %}{{ value.x }}{% endraw %}'

Configuration variables:

• command (Required): The action to take to get the value.
• name (Optional): Let you overwrite the the name of the device. By default name from the device is used.
• sensor_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.

{% linkable_title Examples %}

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

{% linkable_title SickRage %}

Check the state of an SickRage instance.

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

{% linkable_title Check RasPlex %}

Check if RasPlex is online.

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

An alternative solution could look like this:

binary_sensor:
  platform: command_line
  name: Printer
  command: ping -c 1 192.168.1.10 &> /dev/null && echo success || echo fail
  payload_on: "success"
  payload_off: "fail"
