A running record of what has changed on WLED System Architect: new tools, updated guides, and corrections.
October 2026
- New pages: How the Calculator Works (every formula and threshold the Power Calculator uses, with a worked example), Contact, and this page.
- Terms & Conditions and Disclaimer pages now display correctly.
- Calculator layout: removed the empty advertising panels beside the Power Calculator, so the results use the full page width.
- Site maintenance: every page now has a single web address (addresses ending in a slash redirect to the version without one), and unused search markup was removed from page headers.
September 2026
- Power Calculator parts list: the Controller and LED Strip rows now change when you change the controller or strip type, with matching purchase links. Parts are listed in build order (controller, LED strip, power supply, wiring, fuse, level shifter, data resistor), and the parts list now appears above the system topology diagram.
- Buying Guide: updated for 2026, with direct purchase links added to each recommended LED strip.
- Hardware Database: purchase links refreshed for controllers and development boards.
- Home Assistant guide: the WLED and Home Assistant integration guide is now in the Guides menu.
- Simulation Lab: added to the main navigation. It opens directly in the Layout Designer.
