Geevon Indoor Outdoor Thermometer Wireless with 3 Remote Sensors, Digital Hygrometer Indoor Thermometer, Temperature Humidity Monitor Gauge with 200FT/60M Range

Works well and tells us the temperature in each room with the other sensors. small sensors are easy to place and one outside helps us regulate the house. They have not needed batteries changed since we bought them and seem to have no problems with outside weather with only the porch overhang for covering. The base is easy to read with large numbers.

This is perfect for my application - monitoring the temperatures of 3 separate freezers. The design is very clean, and setup is a snap - you can be up and running in 10 minutes. The sensors are compact and monitor not only temperature, but also humidity. Would definitely purchase again - highly recommended.

Fantastic... these work exactly as they should, and the base can be hung on the wall, stuck on the wall with velcro if you have some, or dragged around and sat down wherever you happen to be at the time. I'm able to keep an eye on three different parts of my basement, as well as the upstairs which is displayed as number four on the base. I wish they would make these with even more than three remote sensors. It would be really nice to have a total of seven remotes and one for the endorse built into the base as it is now. Accuracy is off by just a bit...but it is precise. In case you don't know, Precision means the readings will be the same given the same conditions, whereas accuracy means the readings will be accurate. You don't always get both, but if you get one, Precision is better.

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.

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.

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.

Display and blinking connection light on one of three the sensors stopped working after 7 months. This was a sensor that was outside. It was generally covered and out of the elements but outside nonetheless. The sensor still connects to the main unit but there is no indication on the sensor itself. Tried different batteries but display is still defective. *Update 2 (12/18/2025) - The defective sensor stopped working completely at 1 year. I opened it up and it had some corrosion on the battery terminals and where the wires are soldered to the board. I cleaned everything up and soldered two new wires to see if it would come back to life. It was dead. After opening it it doesn't look like it's designed for outdoor use. No seal. Other two sensors are still working but they have been used inside only. *Update - The seller contacted me after my review and offered a full refund. I accepted. They then reneged on it and ask for my address to sent a replacement unit. However, Amazon specifically says in the messages to not to give out personal information so I didn't. They are now offering a $7 refund for one of the sensors. This would be fine if they would have led with that. They contacted me first and offered a full refund, I never contacted them about the sensor. I just gave my review for the experience I've had with this unit. I'm not happy with their customer service. It's not about getting a full refund for something I'm still using. It's about them offering it in first place and then walking it back. Again, they contacted me with that offer.

I have two greenhouses jammed in my backyard as well as an indoor plant room in my home. optimal conditions make for happier plants- this thermometer works perfectly for keeping an eye on the temperature and humidity in both my greenhouses as well as the plant room. this set includes the main display thermometer, as well as three wireless remotes. each remote is numbered to easily find the corresponding readings on the main display. the screen is big and easy to read. you have the option to hang the main display or pop out the little easel on the back to set it. *the only bummer is that I didn't realize the main unit it also battery operated with no option to plug it in. you'll need two aa batteries for the main unit, as well as two AAA for each of the three remotes. (the good news? I've had this exact same unit in the past and know the battery will last forever!)

Per il momento funziona bene, ho messo i 3 termometri in più piani della casa ed esternamente ma prendono bene tutti. In più i 3 termometrini hanno anche un display per veder la temperatura anche se è un po piccolo meglio di nulla come molti altri che non hanno nessun indicatore. Per il momento soddisfatto.

Love this system. Using it I have been able to keep the internal temperature of the house below 27degC even with temperatures outside up to 37degC. It allows me to know when to open and close the windows and curtains on either side of the house. Would love a system that hooks up to the computer, that alarms and has up to 10 sensors.

ok funziona e sembra affidabile

Fungerar som jag tänkte mig

Es perfecto para el precio que tiene Las lecturas de los sensores son bastante precisas, aunque la unidad principal con la pantalla grande a veces se desvía un poco Además, se puede cambiar la temperatura de los sensores de Fahrenheit a Celsius: basta con quitar la tapa de las pilas y, a la izquierda del selector de canal, hay un pequeño orificio donde se puede introducir un alfiler y pulsar el botón Sería muy útil que esta información apareciera en el manual de instrucciones
