RemoteLight v0.2 - Multifunctional LED Control Software

RemoteLight is a Java based control software for WS2811/WS2812 (aka Neopixel) and some other addressable LED strips. It offers a modern, user-friendly UI and a lot of features.

Quick Start


Youtube Tutorial available | view Wiring Guide

RemoteLight uses the Glediator protocol for Arduino. Download the Glediator sketch, change the number of pixels and upload it to your Arduino.

Note: seems to be offline. You can alternatively download the sketch here or use the FastLED variant.

Connect the Arduino to your computer and start RemoteLight. Click 'Add' to add a new Arduino to the output list. Then select the correct COM port, enter the number of pixels and click 'Save'. Now you can activate the output by double clicking on it or by clicking on 'Activate'.

Raspberry Pi

Youtube Tutorial available | view Wiring Guide
RemoteLightServer repository

First of all your Raspberry Pi must be prepared to control WS2811/WS2812 LEDs. There is a well described tutorial on > Tutorial <
After everything works, you can move on.
Upload the RemoteLight-Server.jar onto your Raspberry Pi and start it:

  1. Connect to your Raspberry Pi via SSH.
  2. Install Java: sudo apt-get install openjdk-8-jdk
  3. Navigate to the directory where the RemoteLight-Server.jar is located, e.g.: cd /home/pi/
  4. Start the server: sudo java -jar RemoteLightServer-pre0.2.0.8.jar
  5. To stop the server: Type end or press Ctrl + c

Now start RemoteLight on your computer and click on 'Add' > 'RLServer (Raspberry)'. Enter the IP address of the Raspberry Pi in the 'Hostname / IP' field (the Raspberry Pi must be on the same network). Enter the number of pixels and click 'Save'. If the server is running, you can click on 'Activate'.

Note: You can also use the Raspberry Pi without an additional computer. For this you need an OS with a graphical desktop installed on the Raspberry Pi. Start the server (as described above) + the RemoteLight control software, add a new 'RLServer (Raspberry)' output and enter 'localhost' or '' in the 'Hostname / IP' field.

Start server automatically on startup

Youtube Tutorial available

  1. Install screen: sudo apt-get install screen
  2. Edit root startup script: sudo nano /etc/rc.local
  3. Insert the following line before 'exit 0':
    su - pi -c "screen -dm -S [name] sudo java -jar /path/to/RemoteLightServer.jar"
  4. Edit the name of the screen and the file path, e.g.:
    su - pi -c "screen -dm -S remotelight sudo java -jar /home/pi/RemoteLightServer-pre0.2.0.8.jar"

The RemoteLightServer will now start automatically in a new screen when booting.
To open the screen use screen -r [name]. Type end or press Ctrl + C to stop the server. To leave the screen press Ctrl + A and D.


RemoteLight comes with a LED strip simulator in which you can test the effects without a WS2811/WS2812 strip. However, the effects look a thousand times better with a real LED strip 😉.
To use the simulator you need to go to the output menu and click on 'Open simulator' in the upper right corner.
A new window will open. Click on 'Enable' to activate the simulator. Now go back to the output menu and add a new 'RLServer (Raspberry)' output. Enter localhost or as hostname / IP and the number of pixels you want to simulate. Then click on 'Save' and activate the output.

Lua scripts

With the latest update it is possible to write animations in Lua. All Lua files located in C:\Users\[user]\.RemoteLight\lua_scripts (/home/[user]/.RemoteLight/lua_scripts on Linux) are listed in the 'Scripts' menu.

strip.ledNumber()                   Returns the LED number of the current strip{table{r,g,b}})     Shows the colors in the table on the strip
                                    Expects a table with RGB values in a table which is as long as the  led strip
                                    e.g.: {{255, 0, 0}, {250, 15, 0}, {0, 255, 255}, ...}
 		                                   \ 1. LED  /  \ 2. LED   /   \ 3. LED   /  ...
strip.delayReached()                Returns true when the user defined delay/speed is reached
strip.setAll(table{r,g,b})          Sets the entire strip to the given color
strip.setPixel(led, table{r,g,b})   Sets the color of a single pixel
strip.shiftRight(x)                 Shift all colors on the strip x times to the right
strip.shiftLeft(x)                  Shift all colors on the strip x times to the left
strip.shiftOutwards(x)              Shift all colors on the strip x times from the centre outwards
strip.randomColor()                 Returns a random color (a table with an RGB value)

colorUtil.rainbowWheel(hue)         Hue should be in the range from 0 to 360
colorUtil.hsv(hue, saturation, brightness)
colorUtil.rgb(red, green, blue)     Builds a table with the given RGB values

Start parameters

java -jar RemoteLight-pre0.2.0.x.jar [paramaters...]
-tray | -t               start minimized in the system tray
-autoconnect | -ac       automatically connect to last used output
-updatechecker | -uc     check for updates


Since RemoteLight v0.2.1 you can control animations/effects from the console.

start <AnimationManager/MusicSyncManager/SceneManager/LuaManager/ScreenColorManager> <animation/effect/script path>
stop <all/AnimationManager/MusicSyncManager/SceneManager/LuaManager/ScreenColorManager>
color <HEX> or color <r> <g> <b>
list [<AnimationManager/MusicSyncManager/SceneManager>]
