first of all, I'm not sure if this is the correct subforum.
Well, to the issue. I am looking for a smart thermometer that would work in a fridge. In said fridge there are medical vaccines and other medical material that needs to be kept at a certain temperature, GP's office, so not a huge amount, like, 10? 20?, you know. Should the temperature change for various reasons for T amount of time (malfunction of the fridge, power outage), the very expensive material could be compromised/ruined.
Right now the temperature is measured by a simple (dumb) "radio wireless" thermometer (or a wired one, doesn't really matter) sitting on top of the fridge.
Today we received an offer for a smart thermometer that will log the temperature (online, as you need to log the temperature every x hours) and notify us should there be a problem - via an sms, even during power outage. The problem is they want 300 dollars (in conversion) and a hefty subscription fee. They claim it to be medical grade, however it's not and they don't provide any warranty anyway.
Now, I'm looking for an alternative. I know there must be some sort of a "smart" fridge thermometer with logs and wifi and notifications and "normal" subscription or even none at all. However so far I've only found 1 thermometer from La Crosse. None other.
Would anyone have any recommendations?
Wired temp probe is an options, it should survive longer than something placed directly into a fridge.
