Wireless Smart Lighting Relay for Centralized Facility Automation

The USL-Relay is an enterprise-grade smart relay switch engineered to seamlessly integrate standard lighting fixtures, high-voltage circuits, and legacy electrical loads into your centralized UniFi Smart Building network. Designed for discreet in-wall or junction box installation, this compact wireless relay enables automated schedule control, remote power toggling, and sensor-driven triggering across commercial offices, educational facilities, and smart residential spaces.

Circuit Control
High-Voltage AC Load Switch
Connectivity
BLE / UniFi Wireless Link
Installation Type
In-Wall Junction Box Mount
Management
UniFi Console Application

Legacy Circuit Modernization & Automated Lighting Rules

Engineered to eliminate costly wiring retrofits, the USL-Relay converts conventional non-smart light fixtures into fully manageable network nodes. System operators can link the relay with UniFi motion sensors, schedules, or access control events to automatically power down lighting during off-hours or illuminate emergency egress pathways during security alerts.

Smart Retrofit for Standard Fixtures

Brings full UniFi app control, automated scheduling, and power management to existing fluorescent, LED, or incandescent lighting circuits without replacing fixtures.

Ultra-Compact Flush Design

Sized specifically to fit behind existing wall switches or inside standard electrical junction boxes for clean, hidden installations.

Placement / Form Factor In-Wall Conduit / Standard Electrical Junction Box
Housing Construction Fire-Retardant Heavy-Duty Polycarbonate
Application Target Retrofit Lighting, Automated HVAC Fans & Commercial Building Circuits
What is the main function of the USL-Relay?

The USL-Relay turns standard high-voltage lighting circuits and electrical loads into smart, network-connected devices controllable via the UniFi platform.

Where is the USL-Relay typically installed?

It is designed to fit inside standard electrical junction boxes behind traditional light switches or near light fixtures.

Can the USL-Relay be triggered by motion sensors?

Yes, you can pair the relay with UniFi sensors (such as the USL-Environmental) to automatically turn lights on or off based on motion or ambient conditions.

How does the relay communicate with the UniFi controller?

It connects wirelessly via Bluetooth Low Energy (BLE) to nearby UniFi access points or BLE-enabled UniFi gateway devices.
