Visualizing Home Assistant Data with WLED

Published at : 18 Dec 2025

Home Assistant isn’t just for automation, it can create art. In this video, I integrate WLED with Home Assistant to transform real-time smart home data into dynamic LED visuals. Using a WS2812B LED matrix, I display live data like temperature, energy usage, or even water heater activity in an eye-catching way.

This project is a fun and functional way to explore data visualization using WLED and Home Assistant, perfect for anyone looking to add aesthetic automation to their smart home or office.
