What are Electric Relays?

Overview

This is both a switching device and a signal boosting device. It can be used in place of either the Single Channel Receiver or Electric Switch, depending on the scenario. 

Similar to the Electric Switch, the Electric Relay is installed inside a pattress, making it a discrete device, and easy to install either in a room or next to a underfloor manifold and wiring centre.

Each Genius Hub system uses a number of signal boosting devices, such as the Smart Plugs to make the system work reliably, and increasing the life of the battery powered devices by providing easy lines of communication back to the Genius Hub. As an additional function, the Electric Relay will also boost the communication network nearby.
