Temperature sensors in homey

But I’ve Aqara zigbee sensors in fridge and freezer, works great.
Probably those are not-so-good Faraday cages, and it probably depends on the used model
And a DS18B20 is a wired sensor, the Shelly Uni can be put on the outside of the fridge.

@steff :

I haven’t seen one post here. Can you show me the source?

Shelly’s have normal wifi range. If your wifi system covers your home, Shelly’s should work fine.

Yeah, I just posted this one in an other topic:
