LVGL Sensor

The lvgl sensor platform creates a sensor component from an LVGL widget and requires LVGL to be configured.

Supported widgets are arc, bar, slider and spinbox. A single sensor supports only a single widget; in other words, it’s not possible to have multiple widgets associated with a single ESPHome sensor.

Configuration variables

• widget (Required): The ID of a supported widget configured in LVGL, which will reflect the state of the sensor.
• trigger (Optional, string): Specifies which events will cause the sensor to be updated with the widget’s value. One of on_change, on_update, on_value, on_release. Defaults to on_value.
  • on_change: Update only when the user interacts with the widget.
  • on_update: Update only when the value is changed programmatically (e.g. via an lvgl.*.update action).
  • on_value: Update on both user interaction and programmatic changes.
  • on_release: Update only when the user releases the widget after interaction.
• All other variables from Sensor.

Example:

sensor:
  - platform: lvgl
    widget: slider_id
    name: LVGL Slider

NOTE

Widget-specific actions (lvgl.arc.update, lvgl.bar.update, lvgl.slider.update, lvgl.spinbox.update, lvgl.spinbox.decrement, lvgl.spinbox.increment ) will trigger corresponding component updates to be sent to Home Assistant if the trigger is set to on_value (the default) or on_update.
