PZEM-004T PC interface app

(Please take a look at my web-based app for PZEM devices. It has much broader abilities than this one.)

PC application (Autoit script) which works with old version of PZEM-004T using RS-232 interface.
Version 1.1 also supports RS-485 devices (PZEM-004T V3.0, PZEM-014/016)

The program has four “displays” to show four parameters that PZEM could supply. Voltage, Current, Power and Energy.
Each parameter has “Log” checkbox which enables data logging into the text field at the bottom of the application window.
Each parameter has “Graph” checkbox, but only one of them (any one) could be checked at the moment.
If any parameter has “Graph” and “Enable” checkboxes checked then the value of this parameter is plotted on the graph.
Graph is capable of plotting last 180 points of data only.
Some delays and timeouts could be adjusted in the menu under “settings” button.
