Geevon Indoor Outdoor Thermometer Wireless with 3 Remote Sensors Digital Hygrometer Indoor Thermometer Temperature Humidity Monitor Gauge with

I use these thermometers in my fifth wheel so I can keep track of the temperature and humidity in the closet, outdoors, in the bedroom, and the living room. For an inexpensive set, they are accurate, easy to set up, and easy to read. I put the outdoor one on one of the slide supports to keep it dry and protected. It's a good set. Read more

Summary: I have installed this base and two remote sensors. The temperatures displayed appear to be accurate within the specified limits compared with other thermometers. I can not verify the humidity readings as I do not have anything reliable to compare to. Ordinary setup (without the alarms) was very easy. It came in a box that was easy to open and not in a blister pack that requires the user undue hardship. I highly recommend this unit. Detailed stuff: This unit works very well. I did not need three remote sensors, but the reviews were almost all good and the price was reasonable. Compare that to some other perhaps better known brands (at a higher cost), those had too many negative comments. So I bought this unit. Ordinary setup is very easy. Setting alarms appears to be a bit difficult and the instructions are a bit confusing for that. I don't want alarms, so hopefully they are all turned off. One note on the instructions, the detailed instructions say, "To change the channel option on the outdoor sensor open the battery compartment cover, on the upper left side is a button." No there isn't. The channel selection is made by setting the three position switch at the top of the battery compartment. May be a no brainer for many, but I thought I'd mention it. Also the instructions say not to place the unit within three feet of electronic devices. My indoor unit is right beside my computer monitor and less than three feet from the computer. I'm not experiencing any trouble. Your results may differ. I set up the outdoor sensors (I set up two) under a bay window on the north side of the house so they are always in the shade and protected from other weather elements. Early this morning, before the sun could have an influence on the outside temperature, both outdoor sensors were reporting the same exact temperature. Comparing those readings with a personal weather station about a block away, all the readings, including humidity level were the same. At about noon, the personal weather station about a block away was reporting a temperature ten degrees higher than what my outside sensors were reporting. I often wondered if that personal weather station was inappropriately installed, having compared that to the remote unit I am replacing (a Radio Shack unit I have used for about 15 years). Seems likely. Read more

Absolutely recommend this! I love having my greenhouse, motorcycle shed, and porch temperatures all together. Works great and looks good at the same time. Definitely 5 ⭐️ stars! Read more

Great item - confusing instructions. Would still recommend. Great price and works great once you get it figured out. Read more

Initial product review: Basically these thermostats work great. Main unit takes 2 AA batts...remote units take 2 AAA batts each. I put them in and they automatically synced up with the base unit. I have one in my garage and one each in the front and back of my home mounted to the deck rail in the shade in the hopes to not get false readings from the sun hitting them. The signal from the one in the garage goes through two walls without any issues...about 30 feet. Temps are within .4 degrees of my calibrated digital thermometer. I have no idea if the hydrometer is accurate as I have no means of verifying it. Purchase with confidence! Read more

I live in an area that has quite a few power outages and I am always worried about my fridge and how warm it gets. My old thermometer stopped working and I bought this to replace it. Plus I thought I could place a few more around my house. Once I got batteries into everything, I left them laying out all next to the receiver to see how well they worked. While they may not read the actually temperature with 100% accuracy they all read the same temp. This is better than some of the scientific equipment I have used in the lab. The humidity was off by 1-2 numbers, but that isn't bad and I am not really worried about humidity as much as temp. I did place one sensor outside and the receiver is about 50 ft away. It is registering it quite without an disruption. I also did put one in the fridge and it is about 20 ft away from the sensor and it works just fine. I also put the sensor in the freezer for a brief time and it did register below zero so seems these receivers do work below zero for anyone who lives in a northern area. I feel both the quality of the sensor and receiver is great. I have no issue seeing the temps on the receiver and do not have to get too close to it. They are large enough to read easily. I did not read the directions or mess with any of the alarm settings, so I cannot atest to how well those work. Read more

I am using this product to monitor temperatures in the refrigerator and freezer sections of our main fridge, as well as a smaller fridge in the basement. For this application, it works great. No issues with the wireless connection to the remote sensors, even the one down in the basement fridge. The main display is easy to read at a glance. And while the individual remote sensors have their own displays, the digits are really small, and hard to read at a glance. Not a big deal to me though. As for accuracy, when I first unpacked the product, I set up the sensors side by side and let them adjust to the room's temperature for at least an hour, then compared the readings. Two of them were within 1 degree of each other, which I though was good, but the third sensor was off by a bit more than that. I wasn't super pleased about it, but the readings were close enough where I did not feel it was worth returning the product. The humidity readings were pretty close to one another as well. Considering the reasonable price and decent performance, I am pleased with this purchase and see no reason not to give the product a 5-star rating. Read more
