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

love the ease of tapping the top for backlight. I have double checked accuracy with a different thermometer, and its always within 1 or 2 degrees difference. I made myself a cheat tab, taped to the edge to easily remember which monitor is where. I would definately buy this again!

The Geevon Indoor Outdoor Thermometer with 3 remote sensors has exceeded expectations. Setup was straightforward, and the display is clear with a convenient backlight for low-light viewing. The sensors connect seamlessly and provide accurate readings from multiple locations, which is extremely useful for monitoring different areas of the home and outdoors. The 200ft transmission range works exactly as described, and the overall build quality feels solid and dependable. This unit delivers excellent value for the price—precise, reliable, and professional-grade performance.

This thermometer unit is fandadgumtastic, I have one main base unit which measures temperature and percentage of dryness in the air, then with it came three individual smaller temperature units tied with the base unit. They report to the base, I've got two inside the house and one other outside on the back porch in a cat community house. All units have different readings. I love this unit. If you want to know the differences in the temperatures in your spaces, you need this wonderful thermometer unit.

i have greenhouses and during the winter you have to monitor the temperature. im getting older and its getting harder to go out in to the cold. These are perfect cause i can see what my tempatures are in each greenhouse without leaving my house. i just love these. Time saver very much.

I have only had this for about a week or so but so far it is working great! I really like it. The display is crystal clear and the remote units seem to work well. I have one outdoors, one in my attic and one in my basement. The one in the attic is about 75 feet away from the main unit, which is 3 floors below.

Great for monitoring temperatures and humidity in multiple places at an outstanding price. My sensors have been in 130 and 20 degree environments and have functioned great battery life appears to be at least one year based on my use. The screen has a backlit function that works well and seems to conserve batteries. The display is ok - monochrome with ok clarity but nothing extraordinary. For the price, the readout is good.

This is a handy monitor system for my apartment. Easy setup. Just add batteries and set them around. I have one sensor for outside, one in the bathroom, and another in a grow tent. The base itself monitors room temperature where it sits. I am uncertain about the humidity accuracy because only the sensor for outside shows a different percentage. The indoor sensors humidity readings are all reading 20%. I cannot make sense of that.

All transmitters won't display on base unit

First of all the control panel is very confusing. Never figured it out. Second is that I am picking up my neighbors wireless thermometers. When I take the batteries out of the sensors I am still picking up data from other peoples sensors. There is no possible way I can do anything about that. Good luck trying to understand the control panel.

The first thing I did after installing my batteries (not included) was place these sensors side-by-side on my counter to test their accuracy. As you can see in the attached photo, despite being in the exact same environment, every single one gave a different reading. Don't waste your money on this brand—they are completely unreliable.
