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
    
  2. The ESPHome bot will respond with a downloadable ZIP file containing the SVG image.

  3. Extract the SVG file and place it in the images/ folder of this repository.

  4. Use the image in your component's index table entry in /components/index.rst.

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

The sx127x only has a shared pin and it works great.
