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

I wanted to be able to regularly monitor the temperature and relative humidity in my workshop, new log cabin and loft. The main unit sits in my upstairs office so that I can see at a glance if I need to switch on heaters or dehumidifiers in the outbuildings. The main unit also records the temp' and humidity in my office.I found the instructions overly complicated but the actual installation was incredibly easy. I simply popped the batteries into the main unit and then into each monitor numbered 1 to 3 - as I did this they each showed up on the main unit. I then placed each of the monitors in their relative building and checked to see that they were updating regularly. That was it - Job Done !!This unit enables me to see at a glance what is going on without having to climb up into the loft or leave the house - very useful when its dark or raining. I am sure that it will very soon cover it's cost by saving electricity as I don't need to leave heaters on ''just in case''. Monitoring the loft unit has already shown that our investment in improved insulation and ventilation is definitely paying off.The best thing of all is that I now feel I am in control of what is going on 24/7 from the comfort of my office.

I wanted to know the humidity in my log store and outside temperature near the cars; does both of these jobs well, but the accuracy is a bit off as it doesn't agree with itself when you line all 4 sensor up on a table next to each other: they can read up to a degree different. I would think that there would be a way to calibrate them better, but don't know how.Wireless connection pretty good. Occasionally one drops out, but the re-connect when brought closer then seem OK still when put back in position.

Arrived and was dead. Had to print 5 different labels and forms to return it.

The user manual makes no sense at all. The steps described in the user manual do not relate to the functioning of the unit. It is impossible to disable the high and low alerts, following the steps in the user manual. The user manual is written in poor English, which makes no sense in a large part. The remote sensors only show degrees Fahrenheit. The main unit does show degrees Centigrade, which is my preference. The screw aperture in the remote sensors is tiny. I’m not confident that the remote sensor will remain in place.

Only thing what could be added is a screen backlight. Other than that works flawless but for the price of it I cannot complain.

Firstly, there are no questions allowed on this product. Secondly, while the main display will change from C to F, the remotes stay at F. Not impressed.

As above

Works well, bluetooth range is good.

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.

Wir haben uns im Sommer ein Gewächshaus gekauft und aufgestellt und da sollte man ja auch die Temperatur kontrollieren.Deshalb haben wir uns dieses Funkthermometer hier bestellt.Es war günstig, schön groß und hat gleich drei Funksender.Es kam schnell und gut an.Und ist schnell in Betrieb genommen.Es empfängt sogar einwandfrei die Temperatur aus dem Gewächshaus durch die Plastikwand und eine doppelt-dicke Steinmauer und etwa 12 Meter abstand.Man kann alles prima ablesen und hat zusätzlich die Luftfeuchtigkeit mit darauf.Seit fast 3 Monaten macht es nun seine Aufgabe einwandfrei.Also gibt es nichts auszusetzen.Würden wir wieder kaufen.

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.
