Cannot easily view state #6
Description
Currently in order to view the temperatures, and baffel state one must connect to the serial output of the microcontroller. Fan, compressor and heater can be determined by looking at the relay module leds but it is not convenient. Delays cannot be viewed at all.
This will be somewhat resolved when the Arduino is replace with a Esp32 which can output via bluetooth / wifi but this is still not as convenient as I would like.
Solution is to add a LCD display that will show the current state.
