This power meter realizes intelligent management with overload protection, electricity monitoring and statistics.
RS-485 communication enables "intelligent stacking"
The SPM-Main communicates with the cloud via Ethernet or WiFi and communicates with the SPM-4Relay via RS-485, which allows stable and multi-terminal long distance data transmission.
To operate the Sonoff SPM Main, the presence of a Sonoff SPM 4 Relay is required .
Power measurement:
Do you want to know the variations in the energy consumption of each stall?
Do you want to achieve the unified management of the entire shopping center?
By controlling the eWeLink app on your mobile, you can monitor your electricity consumption without leaving your home.
Through the eWeLink App it is possible to obtain the energy consumption through a touch.
Overload Protection:
Once overload protection is enabled, there is no need to worry about electrical appliances burning out, which helps remove potential safety hazards.
In addition, it is also possible to set the activated overload delay to avoid spurious triggers.
One SPM-Main can be connected to 32 SPM-4Relays, 128 isolated channels and each up to 20A.
Each SPM-4Relay has 4 isolated channels to help the tenant solve the problem of sharing the electric charge.
Each channel can support a maximum current of 20A, without fear of high-power loads.
You can install SPM-Main and SPM-4Relays step by step by following the user manual.
With the guide rail, they can be easily installed in the right place to make your room simple and tidy.
There is no need to worry about losing important information:
You can insert the SD card into SPM-Main to download and check over 180 days of energy consumption history at any time of day via the HTTP API.
The API allows you to switch between eWelink and DIY modes as needed and provides the following functions:
NB: Sonoff SPM Main and the Sonoff SPM 4 Relay power meter must be used together. The Main Unit must be connected to at least one 4-Relay to function.
