Of course I can tell, if interesting.
This is a small device that contains 4 DC current meters INA219, display SSD1309 and a voltage regulator based on the DC-DC converter like that https://www.maximintegrated.com/en/images/appnotes/818/818Fig03.gif
The device can measure the current in four channels, set the voltage for all four channels together, display this data on the display.
There is a small web server. I have prepared all the files statically. I packed them to gzip and push to SPIFFS as shown in the example HttpServer_ConfigNetwork. The web application communicates with the device via the WebSocket to transfer current data and control commands.
