Depending on your implementation environment, you can choose between official desktop tools, web applications, or open-source developer libraries. Official Peacefair Master Software
The PZEM‑017 requires the correct current range to be set in software to match the external shunt (50 A, 100 A, 200 A, or 300 A). If the range is misconfigured, all current and power readings will be wrong. Using the change_settings.py script from the croutonso repository, select option 3 and enter the shunt’s full‑scale value in amperes. The same setting can be applied via Modbus write operations in any of the other libraries.
Depending on your technical comfort level, there are three primary ways to interface with the PZEM-017: 1. Official Peacefair Factory Software
Once you have downloaded and installed the software, follow this configuration guide. pzem-017 software download
If you are building an IoT project, you will need a library to bridge the PZEM-017 with your microcontroller.
The manufacturer (Peacefair) provides a Windows-based software tool.
for local installation, which supports multiple devices and local data storage. Arduino Libraries : If you are integrating the module into a DIY project, the PZEM-017-v1 Library on GitHub is the standard for Arduino-based communication. Energy Monitoring Software : For Raspberry Pi users, the energyMaster software Depending on your implementation environment, you can choose
Python is the most flexible environment for data logging, custom dashboard creation, and integration with databases or cloud platforms. All examples assume you have the minimalmodbus and pyserial libraries installed ( pip install minimalmodbus pyserial ).

The official tool is basic but provides the core functionality for device setup.
The PZEM-017 is a DC multifunction energy monitor (Voltage, Current, Power, Energy). It typically communicates via or TTL . You need software to read data, calibrate, or change the Modbus address/baud rate.
