hdmi_cec:
  # Pick a GPIO pin that can do both input AND output
  pin: GPIO26 # Required
  # The address can be anything you want. Use 0xF if you only want to listen to the bus and not act like a standard device
  address: 0xE # Required
  # Physical address of the device. In this case: 4.0.0.0 (HDMI4 on the TV)
  # DDC support is not yet implemented, so you'll have to set this manually.
  physical_address: 0x4200 # Required
  # The name that will we displayed in the list of devices on your TV/receiver
  osd_name: "HDMI bridge" # Optional. Defaults to "esphome"
  # By default, promiscuous mode is disabled, so the component only handles directly-address messages (matching
  # the address configured above) and broadcast messages. Enabling promiscuous mode will make the component
  # listen for all messages (both in logs and the on_message triggers)
  promiscuous_mode: true # Optional. Defaults to false
  # By default, monitor mode is disabled, so the component can send messages and acknowledge incoming messages.
  # Enabling monitor mode lets the component act as a passive listener, disabling active manipulation of the CEC bus.
  monitor_mode: false # Optional. Defaults to false
  # List of triggers to handle specific commands. Each trigger has the following optional filter parameters:
  # - "source": match messages coming from the specified address
  # - "destination": match messages meant for the specified address
  # - "opcode": match messages bearing the specified opcode
  # - "data": exact-match on message content
  # Actions called from these triggers is called with "source", "destination" and "data" as parameters
  on_message:
    - opcode: 0x36 # opcode for "Standby"
      then:
