Pzem-017 Software Download !full!

For users who want a quick, "plug-and-play" visual experience without heavy coding, several web-based options are available:

Search the for PZEM017 (by @olehs). This library allows you to read energy data directly onto an LCD or SD card logger without a PC.

: You must choose your specific shunt rating (e.g., 100A) in the software settings. If the wrong shunt size is selected, current and power readings will be incorrect.

: Open-source libraries exist for Arduino, but some users have uploaded versions of the PC interface software there. Alternative: Web-Based Interface pzem-017 software download

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

For industrial or custom setups, Python’s minimalmodbus or pymodbus libraries can read the PZEM-017. Node-RED flows are also widely available on GitHub.

uart: tx_pin: GPIO15 rx_pin: GPIO13 baud_rate: 9600 stop_bits: 2 For users who want a quick, "plug-and-play" visual

: Alternatively, you can integrate the PZEM-017 directly into Home Assistant using its built-in Modbus integration if you use an RS485 to TCP adapter like the USR-DR302.

A simpler, single‑file Python interface ( pzem.py ) that works with both AC and DC PZEM modules. It uses the pymodbus library instead of minimalmodbus and is a lightweight choice for Raspberry Pi applications.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | No data read | Wrong COM port or baud rate | Verify in Device Manager / ls /dev/tty* that the adapter appears; ensure software is set to | | Slave address mismatch | Device address changed from default | Use change_settings.py or official software to scan for devices; common addresses are 1, 2, or 247 | | Incorrect readings | Current range not set to match shunt | Use change_settings.py option 3 to set the shunt’s full‑scale value (50,100,200,300 A) | | Communication stops after a few reads | Poor power supply to PZEM‑017 | Provide a stable 5 V from an independent USB charger, not from the PC’s USB port | | Device resets energy at midnight | Normal automatic daily reset | The meter automatically resets daily energy to zero at midnight; to reset manually, write the reset command via Modbus | | “No response from slave” errors | RS‑485 termination or wiring issue | Check A/B line polarity; add a 120 Ω terminating resistor at the end of the RS‑485 bus if multiple devices are daisy‑chained | If the wrong shunt size is selected, current

Connect the PZEM-017 to your DC source (0-300V) and the external shunt. Connect the RS485 terminals (A and B) to your USB-to-RS485 adapter. Install Driver: Run the CH340 or CP2102 driver installer. Run Software: Open the PZEM-017 Master software. Configure Port: Select the correct COM Port (found in Device Manager). Set Baud Rate to 9600. Set Modbus Address (Default is 0x01).

Weeks passed. The PZEM-017 sat under a 3D-printed bracket on the wall, its measurements informing decisions: which charger to unplug at night, how to shift dishwasher cycles to solar-rich noon hours. Tom pushed his code back to GitHub with a clear README and a friendly license. He included notes about checksum verification and a suggested adapter. In the repo’s issue tracker, a new user thanked him for the example that had saved them hours of finger-crossing.
