Add smart control to your existing electrical devices with this Zigbee Smart Relay Switch, designed for in-line installation behind switches, sockets, or directly within circuits. This compact module allows you to remotely control lights, appliances, and other electrical devices, while also enabling automation, scheduling, and smart scenes. It is ideal for converting traditional switches into smart switches without replacing wall fittings. Using Zigbee connectivity, the relay integrates seamlessly with ZHA, Zigbee2MQTT, and Home Assistant, as well as Tuya / Smart Life when paired with a compatible Zigbee hub. It also supports two-way control, allowing it to be used alongside existing wall switches for flexible operation. You can create automations such as scheduling lights, controlling devices remotely, or linking it with sensors for fully automated behaviour. Its small form factor makes it easy to install in tight spaces such as back boxes or junction boxes, making it a versatile solution for smart home upgrades.
