Hi All, I brought this topic up a long time ago and basically procrastinated about doing it until recently. With folks preparing for the future I thought it might be helpful to offer a recommendation for adding a temperature sensor to a freezer when storing NIC. With proposed taxes and impending mail restrictions, stored NIC is/will be a very important item since it will not be easily replaced. If it goes bad, then that's it.
I wanted a way to be alerted of failure and this is it.
Installation was easy. Just drilled a hole through the back of the freezer, inserted the sensor lead and plugged any extra space in the hole with "non-hardening duct seal compound" found at my local Home Depot.
The sensors communicate remotely with a WIFI gateway and will email me should the temperature rise above a specified temperature.
There are many to choose from, some are cheap and some not. I purchased a professional grade by "Monnit" because they have a longer range for communications between sensors and the gateway as well as brand recognition.
Pretty easy to setup and the monitoring service is free provided all sensors are on the same home network. I did a good amount of research and learned to just stay away from systems that don't use sensor leads but instead the whole sensor goes in the freezer. Basically the batteries fail within weeks instead of years.
Hope this is helpful.
