Description:

This PR documents the new Symphony IR protocol support in ESPHome:

  • Receiver side: adds dump entry and an on_symphony trigger; documents the binary sensor configuration with required data and nbits.
  • Transmitter side: adds the remote_transmitter.transmit_symphony action; documents data, nbits, and command_repeats (default 2) to emulate handset behavior.
  • Notes alignment with IRremoteESP8266’s Symphony behavior (single-frame decode; repetition handled by transmitter).

New Component Images

If you are adding a new component to ESPHome, you can automatically generate a standardized black and white component name image for the documentation.

To generate a component image:

  1. Comment on this pull request with the following command, replacing COMPONENT_NAME with your component name in UPPER_CASE format with underscores (e.g., BME280, SHT3X, DALLAS_TEMP):
@esphomebot generate image COMPONENT_NAME
  1. The ESPHome bot will respond with a downloadable ZIP file containing the SVG image.
  2. Extract the SVG file and place it in the images/ folder of this repository.
  3. Use the image in your component's index table entry in /components/index.rst.

Example: For a component called "DHT22 Temperature Sensor", use:

@esphomebot generate image DHT22

- Add symphony to remote_receiver dump list and add on_symphony trigger.
- Add Symphony binary sensor config (data, nbits).
- Add transmit_symphony action with command_repeats and example.
- Note: single-frame decode; sender-native repetition to mirror IRremoteESP8266 (ir_Symphony.cpp).
