One SPM-Main can pair with up to 32 SPM-4Relays. This stackable power meter realizes smart management with overload protection, metadata monitoring and electricity statistics. Do You Have These Same Problems?

Want to check the monthly electricity consumption of the tenements without leaving home?

Want to realize the smart monitoring of the whole shopping mall?

Want to prevent elements from burning out like bitcoin mining machine?RS-485 Communication Allows for "Smart Stackable"

RS-485 Communication Allows for "Smart Stackable"

The SPM-Main communicates with the cloud through Ethernet or WiFi, and communicates with the SPM-4Relays through RS-485, which allows for multi-terminal and stable long-distance data transmission.Power Metering

Want to know the power consumption changes of each stall? Want to realize the unified management of the whole shopping mall? By checking eWeLink App on your mobile phone, you can monitor the electricity usage without leaving home. Through the eWeLink App, you can obtain the power consumption through a touch.

Overload Protection

Once the overload protection is enabled, you do not need to worry about electrical appliances being burned out, which helps remove potential safety hazards. In addition, you can also set the overload delay activated to avoid spurious triggering.

128 Isolated Channels & Each Up To 20A

128 Isolated Channels & Each Up To 20A

Each SPM-4Relay has 4 isolated channels that helps the tenant to solve the problem in electric charge sharing. Each channel can support maximum current of 20A, no fear of high power load.Local Storage With Micro SD Card

Local Storage With Micro SD Card

The SPM-Main supports communication over Ethernet, and also supports local storage. This helps make the power consumption process stable and safe.

*Note: The only capacity supported is 8-32GB, SDHC card.
