Sonoff Stackable Power Meter Main Unit

Description

Sonoff Stackable Power Meter achieves smart management with overload protection, metadata monitoring, and electricity statistics. The SPM-Main communicates with the cloud through Ethernet or WiFi and communicates with the SPM-4Relays through RS-485, enabling multi-terminal and stable long-distance data transmission.

However want to know the power consumption changes of each tenant in your building? Want to realize the unified management of the whole shopping mall, or your tenants? Moreover by checking eWeLink App on your mobile phone, you can easily monitor electricity usage.
