we bought this to monitor the temperatures in different parts of our travel trailer in the winter. We attached the main body to the wall as you come into the trailer. The three sensors went, one into our bedroom, one in the outdoor shower to monitor the exterior temperature, and the last into the "basement" the large storage area accessed through two side doors on the trailer. I did not want things to freeze during the winter. Each of the sensors was no more than 15 feet from the main unit so I cannot comment on any distance reliability but close in they were great. It was nice to monitor the outside, and basement all in one unit. It also let us know that the bedroom was always 2-3 degrees colder then main living area. It also has a light so at night we could check the temperature to see it we needed more heat. Easy to read, accurate and worked well in cold weather. Lowest recorded temperature was 20F. Read more

Good accuracy, self communication with 3 units. Easy on batteries. Pretty close in measurements to other sources, so good for home use. Not many user settings - it just functions when the batteries go in. Nice way to keep track of different zones. One unit died after 18 months- reading crazy temperatures with no way to reset or correct. Read more

The media could not be loaded. I have had one of these now for about 3 years and I really liked it so I wanted to make a video of it just in case you guys were in the market for a good digital thermometer. This set includes 3 sensors plus the base for a total of 4 zones. It not only provides temperature in either Celsius or Farenheit, but it also shows humidity levels in all zones. With a 100 meter range it really works well for me as I use it to monitor my refrigerator, freezer plus indoor and outdoor temps and humidity levels. Read more

This indoor/outdoor thermometer has surpassed the amount I paid for it 5 years ago. I have one thermometer in my crawlspace, one in my shed and another by my well pump, all to gauge freezing temps. It’s been 5 years, all sorts of weather and temps and it’s now given out. I’ve only had to change batteries once during this entire time. I will be buying this product again for replacement of the old one. Read more

I set everything up and it worked fine for 2 weeks. All of a sudden, one of the devices seems to have a broken humidity sensor. Device 2 reads under 15% all the time. I have reset the batteries, no good. I then gathered all the devices, took all the batteries, ran an errand, reset the batteries and have not moved any devices in 2 days and as you can see in the pic, it still reads under 15%. So as of accuracy, i give it a 0. I have also misplaced the manual, so if someone knows how to remedy this, please help. Read more

I have had this for over 5 years and it still works great. The only problem I have is losing or breaking the sensors, as I use it while traveling in an RV. Need a way to reorder new sensors, please. Thanks! Read more
