Product Information

Sonoff’s Smart Stackable Power Meter (SPM) is a professional category, DIN-rail compatible, stackable relay with power meter and overload protection, with up to 20A per channel max. capacity. It can save consumption to a memory card (not an accessory). 

  • Communicated by RS-485. The SPM-Main communicates with the SPM-4Relays via RS-485, which enables multi-terminal and stable long-distance data transmission.
  • Overload Protection. Once the overcharge protection is activated, it protects your device from burns.
  • Works With Alexa & Google Assistant. You can directly ask your Amazon Echo Dot or Echo Show and Google Assistant speakers/smart displays to turn on/off your 4 outputs independently.
