The TCP Binary Sensor is a type of TCP Sensor which is either "off" or "on". In order to use this sensor type, in addition to the configuration for the TCP Sensor, you must supply a value_on value to represent what is returned when the device is turned on.

To enable this sensor, add the following lines to your configuration.yaml:

binary_sensor:
# Example configuration.yaml entry
  platform: tcp
  name: TCP Binary Sensor
  host: IP_ADDRESS
  port: PORT
  payload: "r State\n"
  value_on: 1
  timeout: 5

Configuration options for the a TCP Sensor:

• name (Required): The name you'd like to give the sensor in Home Assistant.
• host (Required): The hostname/IP address to connect to.
• port (Required): The port to connect to the host on.
• payload (Required): What to send to the host in order to get the response we're interested in.
• value_on (Required): The value returned when the device is "on".
• timeout (Optional): How long in seconds to wait for a response from the service before giving up and disconnecting. Defaults to 10.
• value_template (Optional): Defines a template to extract the value. By default it's assumed that the entire response is the value.
• buffer_size (Optional): The size of the receive buffer in bytes. Set this to a larger value if you expect to receive a response larger than the default. Defaults to 1024.
