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

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!

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.

Bought two of them to have in the houses of my animals to watch the temp in the winter. They work good and are accurate however the one set will sometimes pick up the sensor of the same number of the other set. Was easy to set up and seems to be of good quality but I’ve only had them for a few months

Love this gadget. Can turn on heater in garage and monitor from house when temp is appropriate to work in so I dont waste money heating longer or higher than needed, as I dont heat my garage 24/7. Also, I can tell the difference between outdoor temp and garage temp so I can realize how well my garage insulation is performing.

I purchased this thermometer set for an office building that has cooling/heating issues. It worked effectively for monitoring temperatures in different areas of the office. It also kept a week's worth of historical data, which allowed me to demonstrate that the temperatures exceeded OSHA's allowable limits.

This works really good. Was pretty easy to set up. I told my friend and ordered one for them.

This unit, which cost noticeably less than other brands, exceeded my expectations. It measures the temperatures in 4 locations, 3 are remote, and one is at the display unit's location. In addition , it also measures the relative humidity at all 4 locations. the display is easy to read, and appears to be accurate. I would recommend it To my friends and relatives.

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.

Bon thermometre avec 4 indications de température. Nécessite un peu de temps pour caler les indications mais ensuite fonctionne parfaitement. Bonne portée, j'ai un capteur à 25m et ok. Je lis plusieurs avis qui indique un manque de notice en français, cela est faux, la notice est en anglais, français, allemand, espagnol et suédois. Un bon produit à un prix record! A voir dans le temps.

While I haven't tested this for the claimed 60m range (Clear line of site), it is working faultlessly at 35 m from a cupboard in my garage, through plywood doors, across the garden, 90 degrees right through double glazed oak patio doors and across the kitchen. All are reading within half a degrees C of each other when all in exact same environment. Good accuracy and very consistent. Remember to allow a good long time for humidity to be detected well (true of all humidity testing, its never instant on any device). Love this product, and highly recommend it. Great price (29.99), no frills, just works great. (reviewed after 30 days). Super easy to use and reset MAX / Min temps individually.

Impeccable

Funciona muy bien alcanza muchos metros con las sondas

Excellent! Hooks up fast and easy, accurate and reliable. Works 200 feet away from the base, base is indoors too. I have one of the sensors in my shed, so I can see what the inside temperature of the shed is without going there, mostly because I have unheated lithium batteries in there so I need to know what the temperature is in there at all times. This set up works perfectly so far! Comes with 3 sensors plus the base is a thermometer as well so its a very good set up for the money....5☆
