SONOFF SPM-Main smart energy metering system control panel, Wi-Fi

SONOFF control panel SPM-Main is the main device of the SONOFF smart metering system

• For use with the SPM-4Relay expansion module.


• Supports up to 128 channels. With energy consumption accounting.


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


• 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 device requires at least one SPM-4Relay module to function., which is purchased separately.
Features:

• This smart energy metering system central station communicates with the eWeLink cloud via Ethernet or Wi-Fi, and with SPM-4 relay modules via RS-485.


• One control panel allows you to connect up to 32 expansion modules and supports up to 128 channels of 20A control and accounting.


• The SPM-Main control panel allows the use of 8Gb-32Gb SD memory cards, where consumption data can be securely stored. SD cards are purchased separately.


• Remote On/Off - You can turn all channels on and off remotely anytime, anywhere.


• Sync Status - Check the actual status of the relay (on or off) using the app.


• Home equipment electricity consumption data can be downloaded for accounting.


• LAN mode is supported.


• Mounted on a DIN rail, like a relay module, suitable for an electrical cabinet.


• The housing material is made of non-flammable PC V0 safety class plastic.


• Protection for all channels against overload, overvoltage, overcurrent.
