What is esphome-lvgl?

Configuration guidance for ESPHome's LVGL interface system, which builds screen interfaces from ready-made elements such as buttons, sliders, labels, and meters. It supports layouts, styles, themes, pages, touch input, and Home Assistant connections.

Building touch-friendly interfaces on supported ESP32 or RP2040 devices, arranging widgets, styling screens, creating pages, and connecting controls to Home Assistant.

It helps create interactive device screens without positioning every pixel and wiring touch behavior from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.04615
Opus 5	$0.00030	$0.02308
Sonnet 5	$0.00012	$0.00923
Haiku 4.5	$0.00006	$0.00462

Measured 9d ago against content hash 31806e030271, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

esphome-lvgl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ESPHome LVGL Graphics Library

Generate ESPHome configurations using LVGL (Light and Versatile Graphics Library) for creating sophisticated, widget-based user interfaces on graphical displays.

Overview

LVGL is a powerful graphics library that provides pre-built widgets (buttons, sliders, labels, etc.) with built-in touch handling, layouts, and styling. It's ideal for interactive displays that need professional-looking UIs.

Key differences from native display rendering:

Widget-based instead of pixel-by-pixel drawing
Automatic layout management (Flex, Grid)
Built-in touch/input handling per widget
Theme and style system
Direct integration with ESPHome components

Requirements:

ESP32 or RP2040 (ESP8266 not supported)
PSRAM recommended for large/color displays
Display configured with auto_clear_enabled: false
No lambda in display configuration

Quick Start

Minimal configuration with automatic "Hello World":

display:
  - platform: ili9xxx
    id: my_display
    # ... display config
    auto_clear_enabled: false
    update_interval: never

lvgl:
  # Empty config shows default "Hello World" page

Basic configuration with custom content:

lvgl:
  widgets:
    - label:
        align: CENTER
        text: 'Hello World!'

Core Concepts

Widgets

Widgets are graphical elements (buttons, labels, sliders, etc.). Every widget has:

Parent: The container it's created in (page, obj, etc.)
Parts: Sub-elements that can be styled separately (main, indicator, knob, etc.)
States: Visual states (default, pressed, checked, disabled, focused, etc.)
ID: Optional identifier for referencing in automations

Pages

Pages are full-screen layouts. Only one page is active at a time:

lvgl:
  pages:
    - id: main_page
      widgets:
        - label:
            text: 'Page 1'
    
    - id: settings_page
      widgets:
        - label:
            text: 'Settings'

Navigate between pages:

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
