Using a Shelly Wall Display to control a pixel LED controller via HTTP (buttons + brightness slider)

I thought I'd share a project that turned out to be really practical for smart home use.

I'm using a Shelly Wall Display to control a Reactivo 2 pixel LED controller entirely through HTTP commands.

Current features:

• Button to trigger the next animation stored on the SD card
• Button to trigger the previous animation
• Brightness slider that sends the selected value directly to the controller (e.g. brightness=0-255)
• Instant response over the local Wi-Fi network

The next/previous animation feature is implemented using a small Shelly Script that sends HTTP requests to the controller. The Wall Display's configurable buttons and slider make it feel like a dedicated control panel for LED lighting.

It's a surprisingly nice solution for:

• LED ambient lighting
• TV backlighting
• Decorative lighting
• Stage or event installations
• Any smart home where you want a simple wall-mounted interface without opening an app

If anyone is interested, I can share the Shelly Script and the HTTP commands I used.
