I use the Xiaomi sensor in your link in the fridge and it works fine. I have the Aqara hub around 5 meters from the fridge. The Xiaomi sensor is a Zigbee sensor though, not 433 Mhz.

I use an Acurite 433Mhz Refrigerator and Freezer Sensor. My receiver is about 20 feet away. It works perfectly.

I also use a 433 Mhz sensor in a metal mailbox around 40 meters from the house, and that too works fine. I have a larger 433 Mhz external antenna, like this one.
