An IoT Relay is an electronic device that allows users to control electrical appliances remotely over the internet. Typically, it acts as a switch that connects and disconnects power to devices like lights, fans, and heating systems. What distinguishes IoT Relays from traditional relays is their ability to connect to a Wi-Fi network, enabling remote control through smartphone apps, web interfaces, or voice assistants.

    How IoT Relays Work

    At its core, an IoT Relay operates by receiving commands from a user’s device via a cloud-based platform. When a user sends a command, such as turning a light bulb on or off, the instruction travels through the internet to the relay, which then actuates the connected appliance. This communication can be facilitated through various protocols, including Wi-Fi, Zigbee, Z-Wave, or Bluetooth, each with its respective advantages in terms of range, reliability, and energy consumption.
