WLED Max controls WLED lights from your iPhone and iPad: LED strips, holiday lights on the roofline and 2D pixel matrices. It needs a WLED controller (an ESP32 or ESP8266 running WLED) and does not work with Bluetooth or IR remote light strips. New in 1.1.4: Pattern Maker. Build bulb patterns like 2 red, 1 white or start from Classic Christmas, Candy Cane or Diwali Diyas, add motion and watch it on your lights as you go. Every feature is free for one light. A one-time purchase adds unlimited lights. No account, no ads, no subscription. EASY SETUP Open the app and your WLED devices appear automatically. Just tap to add them. Got a brand new device still in setup mode? A step-by-step wizard walks you through connecting it to your Wi-Fi. No computer required. You can also add devices by IP address if they're on a different network. FULL CONTROL AT YOUR FINGERTIPS Adjust brightness with a slider or tap 25/50/75/100% quick-set buttons. Pick colors from a full color wheel, choose from quick-access swatches, or dial in a warm-to-cool white temperature. Set up to 6 favorite effects for one-tap access. Everything responds instantly. 180+ EFFECTS WITH LIVE PREVIEWS Every WLED effect renders a live animated preview right in the grid. See exactly what each one looks like before you apply. Search, filter by category (solid, rainbow, fire, 2D, audio-reactive), and tune speed, intensity, custom parameters, and palette in real time. Pair any effect with any color palette. SEGMENTS STUDIO A visual zone editor with drag-to-resize and full 2D matrix support. Split a single LED strip into independent zones and give each one its own effect, colors, brightness, speed, and direction.
