It's been working great. Still sending temperatures to my phone and alerts if. I just bought a second one to add to an upright freezer. I wish I had gotten it earlier.
It does have an awesome app and essentially when you go to the fridge, you can get the full history minute by minute or hour by hour or whatever it is and all through the night and so you can see when it's getting cold or hot and all that and max and minimum temperatures.
The sensor range and ease-of-use of the app was much better than another temperature sensor brand we've used before. It will be fun to have such an easy way to keep on top of safe food storage temperatures in our RV.
I placed the sensor in the fridge so I could understand the behavior of the different modes. The sensor does everything that I wanted and the app is great!
I got it so I could store medicine and not have the medicine go bad. I was amazed by how much the temperature actually fluctuates in my fridge just with all the people opened it during the day and then how freaking cold it gets at night so it did the job.
