The Ubiquiti UniFi Relay is a compact SuperLink relay designed to integrate third-party sensors, switches, and signalling devices into UniFi environments. Built for flexible automation and control, it enables wireless long-range communication while providing physical I/O interfaces for connecting external systems.

Using UniFi SuperLink connectivity, the UniFi Relay communicates wirelessly over long distances, supporting deployments up to 2 km where compatible conditions allow. This makes it suitable for extending control and monitoring to gates, outbuildings, external sensors, and other hard-to-wire locations.

The device includes two configurable signal inputs, allowing integration with external sensors, switches, or contact-based devices. Two relay outputs provide control over connected systems such as lighting, garage doors, access equipment, or signalling devices, with compatibility for both AC and DC circuits.

Powered by a 12–48 V DC input, the UniFi Relay is designed for flexible installation using existing power infrastructure. Its compact form factor and SuperLink connectivity make it a practical solution for expanding automation, security, and monitoring capabilities across distributed UniFi deployments.
