If you can identify the oem thermostat, you should be able to disconnect it, and run the power-in/switched-out wires through the "Cool" relay in the typical BrewPi hardware configuration, and let BrewPi control your wine chiller.
If you get that far, you can wire an indicator lamp in parallel with the compressor - that is, one side connected to the Cool relay switched-out wire, the other side connected to AC neutral.
Alternatively, you can wire an LED between to the Arduino Cool relay control signal (digital IO pin 5) and Arduino 5VDC with a current limiting resistor (200 ohms or higher value).
As for the Peltier replacement, that's well outside the scope of this thread, and without knowing a lot about the wine chiller an accurate answer would be difficult...
Cheers!
Oh wow, it's easier than I thought. Thank you!
About the peltier, I decided I'll wait for summer and see how it'll behave to see if it's necessary to change or not.
