Warning: Do not use your PC's USB port as the 5V power source for this purpose, as it may damage your computer.

PZEMPlus pzem(Serial2); // Use hardware serial, adjust as needed

The PZEM‑017’s USB port is for signal isolation only – do not rely on it as the main power source. When the measured voltage is below 7 V, you must supply 5 V via the Micro‑USB port, but use an independent USB power supply, not your computer’s USB port . Powering the module from a PC’s USB port can damage the computer.

This is the easiest way to test your device and set parameters like the Modbus address or the shunt type. pzem-017 software download

If your software shows "Communication Timeout" or "No Data," check the following:

: Change the Modbus device address if you plan to chain multiple PZEM modules on a single RS485 bus. 🔍 Troubleshooting Common Connection Issues

If your current readings are zero, use the official Peacefair software to ensure the correct Shunt Value (e.g., 100A/75mV) is programmed into the module. Warning: Do not use your PC's USB port

The is the critical first step for anyone looking to monitor DC power systems, such as solar arrays, battery banks, or EV charging setups. Since the PZEM-017 lacks a physical display, the manufacturer's software is required to read and record data for voltage, current, power, and energy consumption. Where to Download PZEM-017 Software There are two primary ways to obtain the software:

Open on Windows and look under Ports (COM & LPT) . Note the designated port number (e.g., COM3 ). Step 2: Wire the Hardware Correctly

Utilize the ModbusMaster or dedicated PZEM-017 Arduino libraries to build custom data loggers with SD cards or LCD screens. Powering the module from a PC’s USB port

Sites like Arduino Project Hub or GitHub host various versions of the software alongside setup tutorials. Step 3: Installation and Configuration Once you have downloaded the .zip or .exe file:

Developers can use repositories like PZEM017modbus to monitor energy via Python scripts. Connection Requirements
