ROAMiQ Chip: Single-Channel Light Relay with Dimmer

Add clean, ROAMiQ-ready lighting control to your vehicle.

The ROAMiQ Single-Channel Light Relay with Dimmer controls one lighting zone directly through the ROAMiQ ecosystem. It supports up to 12 amps total, allowing control of up to 144 watts of 12V LED lighting from a single channel.

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

Once installed, the light circuit can be controlled from ROAMiQ, from a connected wall switch, or as part of automated scenes and routines.

Key Features

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

Single-Channel Lighting Control: 12A Max
Controls one dedicated lighting zone with up to 12 amps total, supporting up to 144 watts of 12V LED lighting load.

Built-In Switch Input
Works with momentary or toggle-style wall switches, so the light can be controlled from the wall as well as from ROAMiQ.

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

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

Power Monitoring
Built-in power monitoring lets ROAMiQ see what the lighting circuit is drawing.

Reverse Polarity Protection
Designed with reverse polarity protection to help protect the module during installation and wiring.

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

Straightforward Wiring
Six clearly labeled screw terminals and a step-by-step wiring guide for a clean, repeatable installation.

Why It Matters

Lighting is one of the most-used systems in any vehicle build. The ROAMiQ Single-Channel Light Relay with Dimmer brings that lighting into the same intelligent control environment as the rest of the vehicle.

That means cleaner control, fewer disconnected devices, physical switch compatibility, dimming from the wall or from ROAMiQ, and the ability to include lighting in scenes such as Sleep Mode, Camp Mode, Away Mode, Night Mode, or Entry Mode.

Need color or more than one zone? Pair it with the ROAMiQ 4-Channel RGBW Light Dimmer.

Compatibility

Designed for use with ROAMiQ systems and compatible 12V LED lighting loads.

Maximum supported load is 12 amps total, up to 144 watts of 12V LED lighting. 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. Disconnect power before wiring. Proper wire sizing, fuse protection, polarity, load calculation, switch wiring, and system testing must be completed before use.

The switch input accepts a contact to ground only — never connect 12V to the SW terminal. Keep the light's negative isolated: connect it only to OUT−, including any bonded fixture housing. A chassis ground connection bypasses dimming.

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