ROAMiQ Chip: 4-Channel RGBW Light Dimmer

Add full-color, ROAMiQ-ready lighting control to your vehicle.

The ROAMiQ 4-Channel RGBW Light Dimmer controls a complete RGBW LED strip — or up to four independent lighting zones — directly through the ROAMiQ ecosystem. Each channel is rated for up to 7 amps, with up to 28 amps total across the module, allowing control of up to 336 watts of 12V LED lighting from a single compact unit.

Built for campervans, RVs, overland vehicles, marine builds, and specialty vehicles, this module gives installers a simple way to add color and multi-zone dimmable lighting without relying on third-party apps, separate setup processes, or disconnected control hardware.

Once installed, the lighting can be controlled from ROAMiQ, from connected wall switches, or as part of automated scenes and routines.

Key Features

Plug-and-Play with ROAMiQ
Designed to work directly with ROAMiQ. No Shelly app, no separate cloud account, no extra setup.

Four Channels: 7A Per Channel, 28A Max
Each channel supports up to 7 amps (about 84 watts at 12V), with up to 28 amps total across all four channels (about 336 watts of 12V LED lighting load).

Three Channel Modes
Choose the mode that matches the install:
• RGBW — one 4-wire RGBW strip with full color and white control
• RGB + W — an RGB strip plus a separate dimmable white zone
• 4x Independent — four separate single-color dimmable lighting zones

Accurate Color
Color output is gamma-corrected, so the color you pick in ROAMiQ is the color you see on the strip.

Four Built-In Switch Inputs
Connect up to four momentary wall switches. Switch 1 controls on/off and dimming; switches 2–4 recall saved color presets in RGBW modes, or control channels 2–4 in 4x Independent mode.

Saved Color Presets
Set a color in ROAMiQ, save it to a preset, and recall it instantly from a wall switch.

Press-and-Hold Dimming
Press and hold a switch for smooth dimming control. Release at the brightness you want.

Double-Tap Full Brightness
Two taps brings the lighting directly to 100% brightness.

Per-Channel Power Monitoring
Every channel has its own current sensor, so ROAMiQ can see exactly what each lighting zone is drawing.

Overcurrent Protection
Configurable per-channel and total current limits shut the outputs off and report a fault in ROAMiQ if a load draws more than it should. Each channel is also individually fused on the board.

Power-On Behavior
Choose whether lights restore their last state, always start off, or always start on when power returns.

Over-the-Air Updates
Firmware updates are delivered through ROAMiQ, so the module keeps improving after installation.

Straightforward Wiring
Built with installers in mind, using a clear wiring layout and straightforward wiring diagram for a clean, repeatable installation.

Why It Matters

Lighting sets the feel of every vehicle build. The ROAMiQ 4-Channel RGBW Light Dimmer brings color and multi-zone lighting into the same intelligent control environment as the rest of the vehicle.

That means one module instead of several, color control from ROAMiQ, physical switch compatibility, and the ability to include lighting color and brightness in scenes such as Sleep Mode, Camp Mode, Away Mode, Night Mode, or Entry Mode.

Need more than 7 amps on a single circuit? Pair it with the ROAMiQ Single-Channel Light Relay with Dimmer, rated for 12 amps.

Compatibility

Designed for use with ROAMiQ systems and compatible 12V common-positive LED lighting loads. Not compatible with addressable (pixel / RGBIC) LED strips.

Maximum supported load is 7 amps per channel and 28 amps total. Do not exceed the rated output capacity. Verify lighting load, wiring size, fuse protection, switch type, and installation requirements before use.

Important Installation Notes

Professional installation is recommended. Proper wire sizing, fuse protection, polarity, load calculation, switch wiring, and system testing must be completed before use. Switch inputs accept a contact to ground only — never connect 12V to a switch input.

The installer is responsible for confirming that the connected LED lighting load is compatible with the ROAMiQ 4-Channel RGBW Light Dimmer and that all controls operate safely and correctly after installation.
