SDM72 three phase four wire energy meter

This RUST project can read and write a SDM72 energy meter from the command line.

Hardware

The following hardware is required for this project:

  • One or more SDM72 energy meter.
  • One USB-RS485 converter.

Data sheet SDM72 energy meter

  • maximum 100 Ampere
  • Two wire types: 3 phase with 4 wire or 1 phase with 2 wire
  • RS485 Modbus RTU output
  • Pulse Output
  • Bi-directional measurement (import & export)

Compilation

  1. Install Rust e.g. using these instructions.
  2. Ensure that you have a C compiler and linker.
  3. Clone git clone https://github.com/acpiccolo/SDM72-Powermeter.git
  4. Run cargo install --path . to install the binary. Alternatively, check out the repository and run cargo build --release. This will compile the binary to target/release/sdm72.

Getting started

To see all available commands:

sdm72 --help

For RTU Modbus connected sdm72 energy meter:

sdm72 rtu --address 1 --baudrate 9600 read-all

For TCP Modbus connected sdm72 energy meter:

sdm72 tcp 192.168.0.222:502 read-all

You can even use this tool as a daemon for a MQTT broker, the connection is configured via the mqtt.yaml file:

sdm72 rtu --address 1 --baudrate 9600 daemon mqtt
