+
+The ``lvgl`` binary sensor platform creates a binary sensor from an LVGL widget
+and requires :doc:`LVGL </components/lvgl/index>` to be configured.
+
+Supported widget is :ref:`lvgl-widget-button`. A single binary sensor supports only a single widget; in other words, it's not possible to have multiple widgets associated with a single ESPHome binary sensor component.
+
+Configuration variables:
+------------------------
+
+- **widget** (**Required**): The ID of a supported widget configured in LVGL, which will reflect the state of the binary sensor.
+- All other variables from :ref:`Binary Sensor <config-binary_sensor>`.
