Pzem-017 Software Download Portable (ORIGINAL · 2026)

The Peacefair is a widely used, low‑cost DC energy meter that measures voltage, current, power, and cumulative energy in DC systems up to 300 V and 300 A. Because the module has no built‑in display, all data are obtained over an RS‑485 interface using the Modbus‑RTU protocol. This guide collects all the official software downloads, drivers, programming libraries, and third‑party tools you need to read, configure, and log data from your PZEM‑017.

Peacefair typically provides a dedicated Windows application for basic monitoring and configuration. pzem-017 software download

If you're building a DIY monitoring system with microcontrollers, these libraries are the standard go-to: The Peacefair is a widely used, low‑cost DC

If you do not want to install localized desktop executables or need cross-platform access (such as on Mac or Linux), a web-browser application is a popular alternative. import minimalmodbus instrument = minimalmodbus

If you are building an IoT project, you will need a library to bridge the PZEM-017 with your microcontroller.

import minimalmodbus instrument = minimalmodbus.Instrument('/dev/ttyUSB0', 1) # address 1 instrument.serial.baudrate = 9600 voltage = instrument.read_register(0, 2) # 2 decimal places print(f"Voltage: voltage V")

For more advanced data logging or server-side monitoring, Python is the best choice.
