Z1-Mini/PZEM THREE-PHASE ZIGBEE METER

PZEM’s can be connected to the Z1-Mini with an RS485 to UART converter with automatic flow control (so no RE-DE connection is needed). Adapter like this or this can be used.

To use 3 PZEM, modbus ID address of each one must be changed (otherwise all have the same). To do so Peacefair PC software (Windows only) can be used. Download the software and unzip in a folder of your choice (no installation needed); connect PZEM (each at a time) to the computer using a RS485 to USB converter and change PZEM address in Set parameters section (see image below). Repeat this step for each PZEM setting 1, 2 and 3.

With setting below, data are fetched every 20s (Expert tab, Reporting interval).
