Hi folks,
I found this tread very helpful so here's a picture of my outcome.
I ordered the thermostat from aliexpress or ebay and paid 4,09€ with shipping. Quite amazed with the quality and ease of installation. Temp probe is very sensitive. There is some adjustment options in the thermostat as well. I set it to +7°C and it allows the temperature rise to +9°C before it activates the comressor to cool it again to +7°C.
