Note: Some PZEM-017 units use Modbus-RTU over RS485 (check device label). If your module has RS485, you need an RS485-to-USB converter instead of TTL.
Most PZEM-017 boards use a 4-pin connector (5V, TX, RX, GND) connected via a CH340 USB-TTL adapter.
Before downloading anything, check your PZEM-017’s back label:
⚠️ Never connect TTL directly to a PC’s RS232 port—you will damage the meter.

involves selecting the right tool for your specific application, as the device itself is a communication module without a physical display. Below is a breakdown of available software options and their primary uses. Official and General PC Software pzem-017 software download
For basic monitoring and configuration on a Windows PC, users typically use the official Peacefair software or community-developed alternatives:
Official Software: Peacefair provides a dedicated communication software often hosted on merchant pages or via direct download links from manufacturers like Peacefair.
PZEM PC Interface (Web App): A popular cross-platform option is available on SourceForge, which uses the Web Serial API to allow browsers like Chrome to interface directly with the device.
Koshka Web App: An online interface for Peacefair devices is also hosted at Koshka, enabling simultaneous data exchange with multiple units. Development Libraries and DIY Integration If you are integrating the
into a custom project (e.g., using an Arduino, ESP32, or Raspberry Pi), you will need specific libraries rather than standalone "software":
Arduino Library: The PZEM-017-v1 library on GitHub is the standard for Arduino-based projects, handling the Modbus-RTU protocol conversion. Note: Some PZEM-017 units use Modbus-RTU over RS485
ESPHome: For smart home enthusiasts, the PZEMDC sensor platform allows for easy integration into Home Assistant via ESP8266/ESP32 boards.
Python Utilities: Developers can use repositories like PZEM017modbus to monitor energy via Python scripts. Connection Requirements

Peacefair PZEM-017 is a DC communication module designed to measure voltage, current, active power, and energy consumption without a physical display. To monitor this data on a PC or integrate it into a DIY project, you need specialized software or libraries to communicate via its RS485 interface Modbus-RTU protocol en.peacefair.cn Official & Community Software Downloads
Depending on your setup, you can choose between standalone PC software or web-based interfaces: PZEM-PC Interface (Web App)
: A versatile web-based application that works locally on your machine using the Web Serial API. It supports simultaneous data exchange with multiple PZEM devices and stores data in a local database for later review. Download/Access : Available via SourceForge Koshka Web-App Peacefair Official Software Most PZEM-017 boards use a 4-pin connector (5V,
: The manufacturer provides a standalone PC software primarily for basic parameter configuration (like setting the slave address or current shunt range) and real-time monitoring. : Often linked in product manuals or available on the Peacefair Official Website Developer Libraries (Arduino & ESP32)
If you are building a custom monitoring system, these libraries are the industry standard for interfacing: PZEM-017-v1 Library
: An Arduino communication library specifically for the v1.0 energy monitor. It allows reading voltage, current, and energy, as well as resetting energy and configuring alarm thresholds. maxzerker GitHub Repository
: A broader library for Arduino and ESP32 that supports multiple PZEM models, including the PZEM-017, with optimized batch reading for efficiency. lucashudson-eng on PlatformIO Technical Connectivity Requirements
