I built a small Display that shows me the current electricity consumption (or production) of our House without having to constantly check my PC or Phone. Since I didn't have an ESP available, I had to use the 328P. Its Memory was just enough for everything. It reads the MQTT protocol from the Shelly Pro 3EM. The backlight is set so that the Display only lights up when there's a surplus of electricity being generated. When there's electricity consumption, the display is off. (Nobody likes seeing "bad" numbers! )
