Holiday Lighting with Shelly Plus RGBW PM and Firefly Script: A Creative Guide

Holiday lighting can transform your space into a vibrant and festive environment. With the Shelly RGBW2 WiFi LED Controller, you can elevate your holiday decorations even further by adding a whimsical lighting effect using the "Firefly Script." This script emulates the random, flickering glow of fireflies, creating a magical atmosphere as your lights gently brighten and dim.

What is the Firefly Script?

The Firefly Script is designed to bring your LED strips to life by mimicking the natural, random behavior of fireflies. Each strip gradually brightens and dims, and the timing can be customized for each individual channel, giving you full control over the effect. The Shelly RGBW2 is compatible with RGB, RGBW, or white LED strips, supporting up to 288W of combined power at 12V or 24V. This makes it perfect for creating dynamic holiday light displays.

How to Set Up the Firefly Script:

To implement this feature, you'll need to access the web interface of the Shelly Plus RGBW PM and follow these steps:

1. Go to the “<>Scripts” section in the device’s web interface.
2. Create a new script and name it firefly.js.
3. Copy the script from the Shelly repository and paste it into the script editor.
4. Save and customize the script parameters (e.g., delay, transition times, brightness levels).

Key Customization Options:

• Channel Cycle Delay: Control how long each channel waits before starting its light cycle.
• Transition Durations: Adjust how quickly or slowly your lights dim and brighten.
• Minimum and Maximum Brightness: Define the brightness range for each channel, adding to the effect’s dynamic feel.

By tweaking these settings, you can create different visual effects—making some strips transition quickly while others fade slowly for a more random, natural look.

This setup is perfect for anyone looking to add a magical touch to their holiday décor. With the right settings, your lighting can go from festive to mesmerizing!
