I'm using a fibaro door sensor with and additional temp sensor embedded. It's 2in1: I can monitor the door status of the fridge and also the inside temperature.

Hello

Verry nice door switch with temperature sensor
Perfect!
This is new to me
if i look at it 2 fibaro doorsensors 100 euro + a reciever 200-300?
I am Dutch and at the moment the money is not growing on my back ;-)

AliExpress?
see some homemade examples
______microchip attny85 programmable flash microcontroller with dallas temp or temp/humid
______in combination with verry cheap send/recieve 433mhz boards from ebay / amazon / aliexpress / gearbest
Pitty i cannot find preprogrammed premade boards yet (wake up Chinese people? ;-)
above would be less then 5 dollar
