SONOFF SPM-4 smart module with 4 relays, DIN rail mount

SONOFF SPM-4 4-channel smart metering system module, SPM-Main control panel expansion module.

• With energy cost accounting.


• SONOFF smart metering system enables network overload protection, network metering monitoring, and collection and storage of electricity consumption statistics.


• It supports up to 128 channels (up to 32 SPM-4Relay modules), 20A maximum current for each channel, allows you to monitor 180 days of electricity consumption data, and control each channel separately.


• This is a high-performance professional smart home tool that allows you to monitor the electricity consumption of residents or tenants; designed for homes, office buildings, industrial buildings, or even shopping malls.

Note: the module requires an SPM-Main control panel to control it., which is purchased separately.
