into a custom project (like Arduino, Raspberry Pi, or a web dashboard), these tools are highly recommended:
is a DC energy monitoring module designed to measure voltage, current, power, and energy using the RS485 Modbus-RTU protocol. Unlike common AC monitors, it requires external shunts for high-current applications and interfaces with computers or microcontrollers via an RS485-to-USB adapter or UART-to-RS485 modules.

Unlike the Modbus RTU version (PZEM-016) or the AC versions (PZEM-004T), the PZEM-017 uses a custom communication protocol via a (usually with a CH340 or CP2102 chip). The official software, often labeled "PZEM-017 Energy Meter Test Software" or "PZEM-017 Power Monitor Tool," allows you to: into a custom project (like Arduino, Raspberry Pi,
#include <ModbusMaster.h> ModbusMaster pzem; void setup() Serial2.begin(9600); // RS485 connected to Serial2 pzem.begin(1, Serial2); // Slave ID 1 The official software, often labeled "PZEM-017 Energy Meter
Even with the correct download, users face issues. Here are the top 5 fixes:
The module communicates via using the Modbus-RTU protocol. This is distinct from the PZEM-004T, which typically uses a TTL serial interface. Because the PZEM-017 uses Modbus-RTU, you cannot plug it directly into a USB port without an interface converter (like a USB-to-RS485 adapter).
DC energy meter, you can use the official manufacturer application or various community-developed libraries depending on your setup. Official Software & Manuals
