it would be nice if there was the possibility to send sensor values unformatted as a number or percentage, via a serial port.
Similar to the LCD displays, only without formatting, or pure numbers with separators. Together with a small GUI.
Background is the simple evaluation of the data with a microcontroller and display in different ways. I imagine not only LCD or OLED, but rather seven segment display, nixi tubes or an analog pointer display.
That would create a lot of possibilities.
