The PZEM-017 is a popular, cost-effective DC power meter capable of measuring voltage, current, power, and energy consumption for solar systems, RVs, and battery banks. However, unlike its AC counterparts, the PZEM-017 relies heavily on external software to access advanced features like Modbus RTU configuration, threshold setting, and data logging.
If you are searching for "PZEM-017 software download," it is crucial to understand that there is no single "official" driver from the manufacturer (Peacefair). Instead, the device communicates via TTL serial or RS485, requiring specific configuration tools and third-party software to unlock its potential.
For advanced users, several open-source tools provide better flexibility.
| Software / Library | Platform | Function | |-------------------|----------|----------| | ESPHome PZEM017 component | Home Assistant | Native integration | | Python minimalmodbus | PC/RPi | Read/write registers using Modbus RTU | | Tasmota PZEM-017 support | ESP8266/ESP32 | MQTT and web interface | | Node-RED Modbus nodes | Node-RED | Dashboard monitoring | | Arduino library (PZEM017.h) | Arduino IDE | Direct register reading |
The software won’t recognize your meter without the correct COM port driver.
After installing, plug in your adapter. Open Device Manager (Windows) → Ports (COM & LPT). Note the COM port number (e.g., COM5).
| Software | Purpose | Platform | |----------|---------|----------| | Modbus Poll | Read registers, test communication | Windows | | PZEM Utility (by Peacefair) | Official config tool (address, baud rate) | Windows | | QModMaster | Free Modbus master | Windows/Linux | | Serial Monitor (Arduino IDE) | Raw data debugging | Cross-platform |
Not directly. Use a Windows virtual machine (UTM, VirtualBox) or run the Python open-source alternative. pzem-017 software download
| Symptom | Likely Cause | Solution | |---------|--------------|----------| | No response from software | Wrong COM port or driver | Reinstall CH340 driver | | Reading zeros | Wrong communication address | Try addresses 1–247 (default 1) | | Garbage characters | Baud rate mismatch | Set to 9600 or 4800 | | Cannot write settings | SW version locked | Use older PC tool (V1.2) |
| Type | Purpose | |------|---------| | PC/Mobile Application | For reading real-time data (voltage, current, power, energy, cost) | | USB-to-TTL Driver | Enables communication between PC and module (e.g., CH340, CP2102) | | Firmware (rare) | Internal device firmware updates (rarely released; use with caution) | | Library / Script | For custom integration (Home Assistant, Arduino, Raspberry Pi, Node-RED) |
The PZEM-017 is a hardware-first device; its "software" is any Modbus RTU client you choose. For basic setup, download the official Peacefair configuration tool from your retailer’s support page. For serious energy monitoring, skip the proprietary software entirely and adopt ESPHome or Python scripting – both free, transparent, and far more powerful.
Pro tip: Once configured, the PZEM-017 retains its settings. You only need the software once to set the address and reset energy. For daily monitoring, a simple serial reader like CoolTerm (Mac/Win) or screen (Linux) is sufficient.

To set up your Peacefair PZEM-017 DC Energy Meter on a PC, you will need the manufacturer's monitoring software or a third-party Modbus tool, as the device does not have a built-in display. 1. Official Software & Driver Download
Peacefair typically provides a dedicated Windows application for basic monitoring and configuration. Mastering the PZEM-017: A Guide to Software, Configuration,
Official Software: Download the "PZEM-003/017 Master Software" from the Peacefair Download Page or the link often provided by retailers like AliExpress.
USB Drivers: If you are using the included RS485 to USB adapter, you may need CH340 or CP210x drivers to allow your computer to recognize the COM port.
Alternative Web Interface: A community-developed Peacefair PZEM Web App is available for Chrome users, utilizing the Web Serial API to read data without local software installation. 2. Hardware Connection Guide
For the software to communicate with the PZEM-017, the physical wiring must be correct:
RS485 Connection: Connect the A and B terminals of the PZEM-017 to the corresponding A and B pins on the USB adapter. Power Supply:
Voltage > 7V: The unit can power itself from the test voltage source.
Voltage < 7V: You must provide an independent 5V power supply via the Micro USB port. For CP2102 chips: Download from Silicon Labs
Warning: Do not use your PC's USB port as the 5V power source for this purpose, as it may damage your computer.
Shunt Connection: The external shunt must be wired into the negative line of the DC circuit. 3. Software Configuration
Once connected, open the software and configure the communication parameters to match the device's factory defaults:
