The Estron SDM120-Modbus single-phase electricity meter provides MID certified electricity monitoring up to 45A, ideal for monitoring the electricity supply of heat pumps and EV chargers.
The SDM120 meter can be connected to an emonPi / emonBase or Raspberry Pi running our emonSD software stack or emonHub using a USB to RS485 adaptor, once setup the data will appear in Emoncms.
A USB to RS485 converter is needed to read the modbus output of the meter.
Measures: Voltage, Current, Power Factor, Active Power, Reactive Power, Apparent Power, Total Active Energy, Import & Export Active Energy.
Note: The SDM120 is an invasive energy meter which requires electrical knowledge to install, we recommend consulting a local electrician.
Use emonHub to read data via ModBus and post to Emoncms
