This device generates serial data. Port settings are available via this GUI-O interface.

Possible settings are text, baudrate, data offset and random number.
AVR microcontroller is used.

This is another project - connecting GUI-O to the IskraEmeco AM550 energy meter.

It has an RJ12 connector for data connection and power supply (+/-5V).

My application works by displaying all the meter information about energy consumption, power factor,...
The maximum power is adjustable, which means that the relays on each phase are turned on when the power increases above the set limit (white line on the graph).
In this case, you can turn off the electrical consumer that exceeds the set power. This is visible by the RED LED on the bottom.

Everything is remotely controlled/monitored via WiFi.

Attached are the main circuit diagram and screenshots of my Android phone - the main screen and the second screen - the graph.
