Review on 🌡️ (Upgraded) Refrigerator Thermometer with 2 Wireless Sensors and Audible Alarm – Accurate Fridge Temperature Monitor for Indoor Outdoor Freezer, Kitchen, and Home Use (Battery not Included) by Beth Wilson

I recently bought a small inexpensive replacement freezer for my basement. Since it doesn't have a temperature gauge, I didn't know how well it actually works. As a minimum, I needed a temperature sensor that I could install in the freezer to complement the freezer's opaque digital control knob to set the relative temperature. When I searched Revain, I found that there are devices that can do this and much more. In principle, I could put the sensor in the freezer and the monitoring unit in my kitchen. Basically, I could set an alarm to notify me when the temperature is out of range. All of these remote monitoring systems appear to consist of two independent sensor units. Brifit devices have generally received good reviews for their technical performance, but there are some downsides due to the complexity of alarm programming. I ventured this new Brifit device and I'm glad I did. It took me less than five minutes to get it set up and working flawlessly. (Probably partly because I was never interested in the alarm function and therefore never got into alarm programming at all.) I put batteries in the sensor packs and then in the monitor pack. Both sensors were recognized within seconds. I then put one of the sensors in a freezer in the basement and waited with the monitor in the basement until the temperature reading started to drop. I then took the monitor into the kitchen and was happy to see that the sensor was still being recognized and the temperature continued to drop. Now, after spending a day on site, I can see that the freezer periodically oscillates between -5°F and +4°F at the recommended factory settings. Once the sensor probe has reached equilibrium in the environment, you can easily reset the in three seconds to allow the monitor to remember and display past high and low temperatures experienced in that environment. If there is ever a problem with the freezer and I want to make sure it's working properly again, I can simply restart the system and it will erase the old data and will also re-track and record new ups and downs. (but see update below) And now a bonus, after ordering Brifit I found that with sufficient range the second sensor unit could help me solve the problem I was having in my third floor office. It has an independent heating and cooling system that I only adjust to my comfort level when actually working in the office. But too often I forget to reboot the system after work and only realize it the next day when I return to the third floor. I figured if I could monitor the temperature on the third floor from my kitchen, I could easily see if I was wasting energy there. I installed a second sensor on the third floor and it worked perfectly. So Brifit has not only fulfilled its purpose, but also received a nice bonus that will save me a multiple of the device costs. So I ended up having a sensor in the insulating wall of my basement freezer. , and another sensor on the third floor of my wooden house and a monitor in the kitchen on the first floor next to my orchids on the windowsill. All three environments are successfully controlled. Finally, if I ever feel the need to set an alarm, it's nice to know that the monitor is in the kitchen, which is where I'm most likely to hear the alarm. As far as setting up alarms, although some users have documented programming difficulties and don't understand what the monitor readings mean, there is enough of that documentation in Revain user feedback and I'm sure I won't have any problems. Tip: Please note that each sensor unit requires two AA batteries and the monitor requires three AAA batteries. And that the general recommendation is to use lithium based batteries in the sensor unit, especially if it's in low temperatures either in the freezer or outside in winter. For what it's worth, I put AA lithium batteries in the freeze sensor, but I use regular AA batteries for the third floor sensor. So far, so good. Update added on January 6, 2020. Added a photo of the monitor showing how it looks after 24 hours of operation since the temperature history was last reset. This shows the type of information you will receive. For sensor #2, located at the bottom of the freezer, you can see that in the last 24 hours, the maximum temperature reached was +5 degrees Fahrenheit and the lowest temperature recorded was -5 degrees Fahrenheit. You can see that the current temperature in the freezer is -4.2 degrees Fahrenheit and that the temperature is currently falling. For sensor #1, which is upstairs in my office, you can see that the maximum reading for the last 24 hours is 68 and the minimum reading is 62. You can also see that the current temperature is 61.9 and is staying constant. . That's because I didn't turn on the thermostat that morning. "Internal" readings are taken from the temperature sensor in the monitor unit. You can see that in my kitchen on the first floor, he has also experienced a maximum of 68 and a minimum of 60 in the last 24 hours. It is currently at 67.5 and is stable as the thermostat for the house's main oven automatically went up to 68 earlier in the morning. One thing to note. It turns out that this block updates automatically and resets the entire temperature history every 24 hours. sometime in the late morning. This was not described in the product documentation. The automatic reset doesn't really bother me. but it would be nice to know. The documentation is definitely empty, which is a common complaint in user reviews. But I'm still sticking to five stars. I like the technical possibilities and - for now - can live with any temporary confusion.
