Sonoff Stackable Power Meter
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.
Furthermore 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 activate the overload delay to avoid spurious triggering. One SPM-Main can be connected with up to 32 SPM-4Relays. Each SPM-4Relay has 4 isolated channels to help the landlord solve the problem in electric charge sharing. Each channel can support maximum current of 20A, thus no fear of high power load.
You can insert the SD card into SPM-Main to download and check over 180 days of your energy usage history at any time of the day through HTTP API. No need to worry about missing the important information.
**Note : You need to use the SPM-Main Unit as well as the SPM-4Relays of the Stackable Power Meter together. The Main Unit is connected to at least one 4-Relay to function.
