Can some one point me to an example iot freezer monitor sketch using a Arduino nano 33iot and a ds18b20 sensor

What type of freezer and where will you place the sensor?
Thanks for the reply. It is an upright and the sensor is the waterproof version of the DS18B20.
I do have a sketch on the cloud that shows the temp in the serial monitor and also shows the nano 33 online and the serial monitor indicates that the nano has connected to my wifi. However I have been unable to get the temp to update or display on the dashboard. I was thinking this would be a common project and an example might be available.
Where is the sensor during your test? Our upright freezer has a built-in temperature warning and one time the door was blocked from completely closing. About a week went by before the alarm sensed the warming and alarmed.
Test all your system where you can quickly change the temperature and use serial.Print() to show the raw values being returned from the DS18B20. When it works properly. locally, then extend to remote stuff.
