Short Description
The Ogemray 25A Relay is a smart switch with power measurement that allows remote control of high-load electric appliances via mobile phone, tablet, PC, or home automation systems. It can operate standalone in a local Wi-Fi network or be managed through cloud-based home automation services.
It supports remote access, control, and monitoring from any location with internet connectivity, provided the device is connected to a Wi-Fi router and the Internet.
Installation is simple—no rewiring required. It fits into standard electrical wall boxes, behind power sockets, light switches, or in fuse boxes.
The device includes an embedded web interface for monitoring, control, and configuration.
