Internal components will not be exposed to the frontend (like Home Assistant). Only specifying an ``id`` without a ``name`` will implicitly set this to true. - **disabled_by_default** (*Optional*, boolean): If true, then this entity should not be added to any client's frontend, (usually Home Assistant) without the user manually enabling it (via the Home Assistant UI). Requires Home Assistant 2021.9 or newer. Defaults to ``false``. - **entity_category** (*Optional*, string): The category of the entity. See https://developers.home-assistant.io/docs/core/entity/#generic-properties for a list of available options. Requires Home Assistant 2021.11 or newer. Set to ``""`` to remove the default entity category.

Defaults to ``false``. .. note:: Camera uses PWM timer #1. If you need PWM (via the ``ledc`` platform) you need to manually specify a channel there (with the ``channel: 2`` parameter) Configuration for Ai-Thinker Camera ----------------------------------- .. warning:: GPIO16 on this board (and possibly other boards below) is connected to onboard PSRAM. Using this GPIO for other purposes (eg as a button) will trigger the watchdog.

Configuration for M5Stack Camera -------------------------------- .. warning:: This camera board has insufficient cooling and will overheat over time, ESPHome does only activate the camera when Home Assistant requests an image, but the camera unit can still heat up considerably for some boards. If the camera is not recognized after a reboot and the unit feels warm, try waiting for it to cool down and check again - if that still doesn't work try enabling the test pattern. .. code-block:: yaml # Example configuration entry esp32_camera: external_clock: pin: GPIO27 frequency: 20MHz i2c_pins: sda: GPIO25 scl: GPIO23 data_pins: [GPIO17, GPIO35, GPIO34, GPIO5, GPIO39, GPIO18, GPIO36, GPIO19] vsync_pin: GPIO22 href_pin: GPIO26 pixel_clock_pin: GPIO21 reset_pin: GPIO15 # Image settings name: My Camera # ...
