The telnet switch platform allows you to control devices with telnet commands.

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

# Example configuration.yaml entry
switch:
  platform: telnet
  switches:
    projector:
      resource: "host_or_ip"
      port: 4002
      command_on: "PWR ON"
      command_off: "PWR OFF"
      command_state: "PWR?"
      value_template: '{% raw %}{{ value == "PWR=01" }}{% endraw %}'

Configuration variables:

• switches (Required): The array that contains all switches.
  • identifier (Required): Name of the switch as slug. Multiple entries are possible.
    • resource (Required): Host or IP of the device.
    • port (Optional): Port to connect to. Default is 23 if not defined.
    • command_on (Required): Command to turn device on.
