A Smart Home Relay is an electronic switch that is integrated into a smart home system to control electrical devices remotely. Typically connected to a Wi-Fi network or communication protocol like Zigbee or Z-Wave, the relay connects various smart devices in the home, such as lights, thermostats, door locks, and even appliances. The core function of the relay is to allow users to control these devices from a distance, providing convenience and enhancing the functionality of their home automation system.

    At its core, a relay acts as a mechanical or electronic switch. When triggered by a signal from a smartphone, voice assistant, or pre-set automation rule, it either completes or breaks the electrical circuit, thus turning a device on or off.
