ORIA Refrigerator Thermometer, Wireless Digital Freezer Thermometer with 2 Wireless Sensors, Audible Alarm Indoor Outdoor Temperature, Min and Max Record, Backlight for Home, Office, Restaurants

This is a durable set with outstanding accuracy. I only wish there were better ways to mount these inside the interior walls of the fridge and freezer.NOTE: When inserting batteries, it is critical that the batteries be inserted in the sensors FIRST. Finally insert batteries in the main console to activate the reading. In my case I did not get a reading for one of the sensors so I reinserted the batteries in the sensors again. Immediately afterwards I removed one battery in the main console and reinserted it TO RESET the system. This is a weird flaw in the design but it is what it is. It worked and all sensors were detected. If one sensor does not read in the console, do not think it is defective. Reinsert batteries in the sensors first followed by reinserting them in the main unit last. This is important to mention.

I am still having difficulty getting the unit to work properly. It requires strictly following the instructions to get the sensors to work on the control monitor. There may be a problem if any other monitors located near this unit. I am still waiting to see if it will register the proper temps inside the refer and freezer.

Order was missing 1 sensor but they di send a fast replacement and all is working as advertised

Works, easy to use for many applications

I LOVED this for 9 months. Bought late March 2022... Dec 31, 2022 one of the sensors stopped working. I put fresh batteries in it (yes, I tested them with a battery tester, they are new and full) and it won't work. Won't come back on at all. Not with different batteries, just... nothing. Really frustrating as I bought this to monitor my basement Temps where one of my special needs kids sleeps as it gets 10-15 degrees colder than the rest of the house. I was relying on this to know when to turn on the space heaters for him. Very disappointing because this was a 5 star product, hands down, no question... until the sensor stopped working. Not ok to have it stop working after 9 months. I guess they just don't last. Just waiting for the next one to die on me. Then the unit is not helpful any longer. :-(

Reasonable price. Easy to read because all temps. are displayed simultaneously as opposed to my previous one that switched between each reading, which was very annoying. Defiantly recommend this one.

* The first thing I noticed about this unit is that it has no alarm, even though the product description claims that is does.* When unlit, the display is easy to read if the ambient room light is sufficient. However, when the backlight is activated, the numbers fade out when viewed straight on, and can only be seen if you look down from above, or up from below.* Although there is a "Light" button, pressing -any- button activates the light. Given the problem with the display, this means that it is next to impossible to read the display when you're trying to do any set up.* There is no way to calibrate the receiver, or any of the sensors. This would not be a problem if the factory set up gave accurate results, but it does not.* Range is good. I set sensors up to 75 feet away, and the main unit had no problem connecting with them -- even the one I put inside a refrigerator.* Temperature readings were reasonably accurate and consistent across the three sensors.* Humidity readings were more than 10% off (low), and differed by as much as 5% across the three sensors, sitting side-by-side on the table. This would be a better item if they left off the humidity feature, and just sold it as a thermometer.* Bottom line: it works as a thermometer, but it has other issues. Since I bought it for the alleged alarm feature -- which is missing --, I'll be returning it.

The instructions were not great and I am still a little confused about some of the details of use, but the major thing to me is that it works. They have been running for about a month with only one minor outage for one of the sensors for about 20 minutes. I wasn’t quite sure what to do, so I did nothing and it started working again.The alarm could be louder or even work with your cell phone.I would love to see Nest or TP-link come out with a similar product, but until they do this will work well. If you have a secondary or tertiary refrigerator or freezer, this is a no brainer. Moreover if you are like me and have a variety of homemade soups, sauces, and casseroles in your freezer the time and money investment in your freezer or the cost of groceries in a refrigerator is priceless. One simple notification can save a great deal of heart break. And accidents don’t happen when the units are empty. For me I find it is when they are crammed full around holidays.Edit: nearly a year since we started using it, we could not be more pleased. During the pandemic both our college age sons were at home and both refrigerators and the upright freezer stayed full. The alarm actually has avoided a near catastrophe when after a big grocery store run the freezer door didn’t completely close. We were notified before anything melted and just a small amount of frost had been created. It is amazing how such a simple thing can add such security. If you have multiple refrigerators or freezers, I can only describe this as the cheapest insurance you will ever buy....

Lo adquiri por su utilidad para el confort de saber la temperatura en cada espacio en vivienda o y trabajo, y tomar decisiones de refrescarlos.

todo bien, se realizaron pruebas en entrada y salida de una unidad evaporadora

Puedo tener las lecturas de temperatura y humedad de las habitaciones que deseo,Me hubiera gustado que contara con su propia fuente de alimentación porque no la trae.

El aparato es sumamente preciso y muy fácil de usar.Lo coloque al lado de otro termómetro y todos marcan la misma temperatura +/- 0.3 °C
