The Sonoff smart power meter is perfect for monitoring and managing electrical devices. You can connect up to four devices (each up to 20A), such as heating systems, machinery, or lights, and monitor their power consumption via WiFi or Ethernet. The system works with the main module (Sonoff SPM-Main), which connects to the network and transmits data remotely. In addition to monitoring consumption, it provides overload protection – if the power exceeds a set limit, the module automatically shuts off the device for added safety. Ideal for homes, offices, or workshops where energy management and safety are key.
