SLWF-11 User Manual — Part 5 of 10
The A-SLWF-11 has a built-in infrared receiver (on GPIO4), so you can control your lights with the supplied IR remote — handy when Wi-Fi or the app isn't convenient. The remote is a standard multi-function WLED-style handset with power, effect, speed, brightness, colour and music keys.
Enabling the remote in WLED
- Open the WLED web interface → Config → LED Preferences.
- In the Infrared section, set the IR GPIO to
4. - Select the matching IR remote type (this handset behaves like WLED's 24-key RGB profile; if some keys don't respond, try the other 21-/24-/40-key options).
- Click Save, then point the remote at the controller and test the buttons.
Button reference
| Button | Function |
|---|---|
| On / Off | Turn the LED output on / off (standby). Off does not power down the controller. |
| AUTO | Start automatic effect cycling — WLED steps through effects on its own. |
| MODE+ / MODE− | Switch to the next / previous effect (mode). |
| SPEED+ / SPEED− | Increase / decrease the current effect's speed. |
| ☀ (upper) / ☀ (lower) | Brightness up / down. |
| R · G · B | Set a pure red, green or blue. Repeated presses can step through shades on some remote profiles. |
| Colour swatches (yellow, cyan, purple, magenta, dark blue, green, red) | One-touch solid colours for quick scene setting. |
| W | Set white / warm output (full white on RGB strips). |
| COLOR | Return to solid-colour mode / cycle the colour palette. |
| ♪1 / ♪2 | Sound-reactive ("music") modes 1 and 2. |
| 🔒 (lock) | Lock the remote / freeze the current setting to prevent accidental changes. |
Sound-reactive keys need a microphone The A-SLWF-11 has no built-in microphone, so the ♪1 / ♪2 keys only produce sound-reactive effects if you add an external analog microphone on the ADC pin (see §9 Pinout) and flash a sound-reactive ESP8266 build.
Tips
- Keep a clear line of sight to the controller's IR window; typical range is a few metres.
- If the remote is dead out of the box, pull the plastic battery-insulation tab (or fit a fresh coin cell, e.g. CR2025).
- Exact key behaviour depends on the selected WLED IR profile. For full control you can define a custom IR mapping (an
ir.jsonfile) — see the WLED docs.
