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:

@esphomebot generate image DHT22

Walkthrough

Documentation for the HTU21D sensor model option was expanded with an advisory note that some boards may be mislabeled and to try HTU21D if I2C errors occur; the default remains HTU21D. No functional, configuration, or public API changes.

Pre-merge checks and finishing touches

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Linked Issues Check	⚠️ Warning	The change only adds documentation advising users to try the default HTU21D model if I2C errors occur, but the linked issue required diagnosing and implementing a code‐level mitigation for hardware NACK and boot loops on ESP32 boards.	Please implement or reference a code‐level handling or detection of mislabeled HTU21D devices to fully address the I2C hardware NACK and continuous reboot issue described in issue #10738.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title “[htu21d] Add note about hardware version” clearly identifies that the primary change is adding a note regarding hardware version in the htu21d documentation and concisely summarizes the main adjustment without unnecessary noise or vagueness.
Out of Scope Changes Check	✅ Passed	All modifications are confined to the htu21d documentation file and directly relate to the stated objective of adding a hardware version note without introducing unrelated files or code changes.
Description Check	✅ Passed	The pull request description succinctly states the addition of a hardware version note and references the related issue, which directly pertains to the documented change in the htu21d component.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
