Overview
Ogemray SW40 is a high-capacity Wi-Fi smart relay with power measurement, designed for controlling large electrical loads up to 25 A (6000 W). It is suitable for demanding residential and light industrial applications where accurate monitoring, safety protections, and reliable switching are required.
The device operates without a hub, connecting directly over Wi-Fi, with Bluetooth used for setup and local functions. It includes real-time power measurement, multiple protection mechanisms, and supports advanced local automation via scripting. Large terminals and wall-mount anchors make it suitable for higher-current installations where physical robustness matters.
