This is a great product, and does exactly what it promised. The price is currently a little bit steep (~$40) per unit when compared to others, but you get back a well working and useful device. The Bluetooth range is incredible, even with the signal blocked by stainless steel doors.
The reason for this purchase was a kitchen refrigerator and freezer combo that appeared not to cool well, or at least very inconsistent. Before purchasing two of these units, we cleaned out the coils located under the combo that were full of dust. First with a coil brush to get the biggest dust bunnies out, then a final clean with a battery powered little leaf blower (Makita). The leaf blower did the trick and made everything look like new. This required unplugging the combo and removal of back plate to make compressor area accessible for cleanout.
Moving on from cleaning the combo, I reviewed multiple solutions of how to monitor temperature in both refrigerator and freezer compartments. First I was set on some high grade mechanical temperature meters, but after thinking about it for a little longer I didn't want to have to open and close the doors all the time in order to see what the temperature was. Also, the temperature is always moving down when the compressor is running, and up when it is not. The refrigerator and freezer operate in a bandwidth, and when it is equipped with auto-defrost you might think the freezer is not working while it is just cycling through a defrost cycle.
Then the sensor itself; I'm tech savvy due to my profession as an engineer, so I typically try to buy quality over quantity. First thing I did was checking it's accuracy with some lab grade equipment, and readings were well within 35% of the maximum allowable tolerances (see specs). These units can easily be calibrated via the app, which I did, although they would have been fine without these minor adjustments.
The app is easy to use, and has hourly, daily, weekly, monthly and yearly graphs that show min/max and average for selected time range. There is an option to download all data points to a computer or your phone. Very useful to see performance over time, and whether or not it is time to clean the coils. With an auto-defrost feature, you'll be able to tell exactly how many times it runs this feature. If it starts happening more often, you may have door seals that are worn, or usage might have been going up (open door more often, and this cycle runs more often. It was a surprise seeing the freezer go up to 41°F about once a day.
That gets me to one point of improvement I would like to see in the app; there needs to be a delay that can be set before it warns you when temperature reaches a certain level for a determined time. For instance, I set my freezer alarm at 9°F. I want the app to notify me only when the temperature is above this temperature for more than 2 hours. Currently, I get notifications every time the auto-defrost cycle is running, which leaves temperatures above 9°F for a little over an hour. For this reason I had to remove the alarm, or basically set it at over 44°F, which now will not warn me anymore if freezer contents are over 9°F for an extended amount of time.
Last thing I would like to mention is that you'll need to give the app continue location access, which is only related to Bluetooth access. You can turn it off to allow only when you open the app, but it would then not give you an alarm anymore unless you open the app. Without alarms set you could just give access only when the app is open.
This item is definitely a winner, but I still hope Tempi.Fi will add a delayed alarm feature to their app so it can be used in refrigerators or freezers with auto-defrost function, or to limit alarms when loading groceries. It comes with double sided 3M tape, but instead I used "3M Dual Lock" velcro so I easily can take the units out when replacing batteries (they should last 1 year). Perhaps another improvement idea. I hope their will be a gateway soon, as they state they are working on it, and it would allow for temperature checks wherever you are.

Product Description
BE ALERTED RIGHT AWAY
Whether your are monitoring your backup freezer, a baby's room, or the temperature in your doghouse, you need to be made aware of any temperature or humidity problems before its too late.
This sensor sends alerts directly to your phone. You can set high or low temperature and humidity alerts and will receive a notification when the temperature or humidity crosses the thresholds, allowing you to take control of the situation, make necessary adjustments, and mitigate damage.
Not in range when the alert occurs? No problem. If you are out of range when the sensor triggers an alert, you will get the alert on your phone when you come back into range.
WIDE RANGE OF OPERATION
This sensor has a theoretical range of 300ft in a space with no obstacles in its path. Its typical range is between 60 – 120ft., depending on various factors, such as piping and the type of wall material. As long as you are within range, the sensor will have no problems transmitting data to your electronic device. Out of range? No problem, get sync your data and get alerts you missed when you get back into range. In a modern 3,000 square foot home, the sensor can usually be detected in any room.
FOR LARGE TO SMALL APPLICATIONS
This mini wireless sensor can fit just about anywhere. Whether you are placing it in the back of your freezer, a cigar humidor, or a wine cooler, you shouldn't have a problem placing the 1.57" x 1.57" x 0.65" sensor (40 x 40 x 16.5mm).
The sensor is not waterproof because it has a humidity component that needs to be directly exposed to the environment. The sensor can be used outside if it is protected from water, rain, and snow.

OPERATES ON A SINGLE BATTERY FOR OVER A YEARThis mini wireless temperature sensor is built to operate 24/7 indoors or outdoors. If placed outside, it is best to keep it in an airtight ziplock bag to protect against water, rain, or snow. Don’t worry, even inside a protective bag the sensor should still report an accurate temperature reading. The device relies on a CR2477 coin cell battery (included in the package), which should provide power to the sensor for more than a year. |
LEVERAGE THE POWER OF UNLIMITED DATAThe downloadable app is designed to automatically keep an unlimited, minute-by-minute history of its temperature and humidity readings. You may export and generate the entire history - or just parts of it - as a CSV file, which you may open in Microsoft Excel or Google Sheets. Discover patterns and pore over years of temperature-reading history through the app's interactive and intuitive graphs. |
PRESERVE YOUR BELONGINGSHigh levels of humidity can easily cause wooden furniture, instruments, and flooring to warp, bend, or crack. This wireless sensor is a must-have if you keep antique pieces, musical instruments, or art collections in your home. Keep a temperature sensor inside your instrument cases, in your home art gallery, or your antique furniture showroom to stay updated on room temperature readings. |

Almost good
I want to like this product. I love the app and the data that you get from the sensor, but you have to be within 10 ft of the sensor to pick up on the data in the app.I have one sensor in the freezer in my garage and I cannot pick up the signal in my bedroom and my house isn’t that large. I have the second sensor in my chicken coop and it’s way too far away for me to get alerts when it gets too hot or cold. So, what is this really good for if you have to get right next to it?
