Temp sensor in Fridge Freezer

[luberth]

Is it possible to putt an wireless tempsensor in a fridge
will the signal come tru

or is it better to use flat ghost wire electric copperfoil tape to get a wired sensor iside the fridge/freezer
anyone experience

think it wil be nice to log the temp of fridge freezer.

I have one (434 MHz) in the fridge for a least 8 years without any problems.

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

nu eens kijken wat voor ontvanger daar bij moet voor een raspberry pi
now search for a 433mhz reciever for raspberry with TFA code

better to use a sensor outside the fridge like this one: https://www.conrad.nl/p/renkforce-ft007 ... hz-1425530

I'm using a Telldus fridge sensor https://telldus.com/produkt/temperature ... be-433mhz/, it has a thin wire leading into the fridge.
For reading temperature it works, I get message from Domoticz if temperature goes above a set point.

In my fridge a Fibaro Door sensor could not connect to network when placed inside, and there is sadly not enough clearance to attach it outside.

yes its possible

maybe did it in a strange way
but it is working with a cheap chinese digoo wireless 433mhz teperature sensor
