Product description: Sonoff SPM-Main - central unit of energy monitoring system - Ethernet / WiFi - Android / iOS application
The Sonoff SPM system is an advanced solution for monitoring and managing energy consumption in various environments, such as offices, shopping malls, and server rooms. The SPM-Main central unit communicates with the cloud via Ethernet or Wi-Fi , and with SPM-4Relay modules via RS-485, ensuring stable data transmission over long distances. The system allows you to connect up to 32 SPM-4Relay modules to one SPM-Main unit, which gives you the ability to monitor up to 128 channels simultaneously. Additionally, thanks to the SD card slot (supported cards with a capacity of 8 GB to 32 GB , SDHC), it is possible to locally store energy consumption data from the last 180 days, with access via the HTTP API interface. The controller is designed for easy integration with electrical systems - DIN rail mounting allows for quick and convenient implementation in existing infrastructure.
