Indoor Outdoor Thermometer Wireless, 4.5 Inch Display Digital Hygrometer Thermometer Temperature Humidity Monitor with 330ft Range Sensor and Adjustable Backlight

Excellent choice! This thermometer is by far one of the best we have ever used. We have one in our greenhouse and both shops. The temps are clearly shown and spot on. The only downside is that it is not wireless, so we can't check them from our phones. HOWEVER, it is great to be able to get up in the middle of the night, check on the greenhouse, and not have to go out there in the cold to see if the heater is still working. If you want a great thermometer that is accurate and can track multiple locations, this is the one for you. Highly recommend and would purchase it again if needed. Oh, and one more thing, the ease of set-up is amazing. It works exactly like it should and if it does go offline, it is super easy to synch back to the main display.

If you'd rather not read my glowing review, here is the short of it: For anyone shopping for an *economical*, *reliable*, wireless, multi location temp / RH% setup, stop shopping. Saving 5 or 10 bucks once you unpack it, Read the instructions, place the remotes, evaluate the readings and, then, possibly discover shortcomings that warrant you're having to return it - well, it's just not worth it. Save the money and the headache. Buy this unni. You'll be happy with it and you won't have to look back, wondering if you would have been better off purchasing this or another unit. Now for the specifics of my experience with this unit: This unni four location sensor set is the best of 3 I purchased in a 10-year period I purchased this product in July of 2023 and have replaced only one of the batteries in one of the 4 units (The configuration I purchased was one base unit along with three remote sensors) All 4 of the units in this kit have provided very accurate readings consistently when placed in same location (to ensure that they read the same in the same environment). The base remains in the same spot and has been consistent in readings for almost 3 years. Each of the remote units, I have intentionally rotated interchangeably in their respective locations and all have been accurate to within one degree and 1% RH. Over approximately 10 years, I've purchased at least six different sets of hygrometers (with three of the sets being good and accurate) and have rotated those sensors to compare with these and have found all measurements to be close to identical. The two other remote kits from semiexpensive and well-known manufacturers were garbage by comparison and other the multi-unit sets of non-remote sensors, while accurate, did not provide the convenience of a centralized dashboard. I highly recommend this "unni" branded multi location wireless thermometer/hygrometer far above the other two unjustifiably expensive, big brand name multi-sensor kits. This unni branded set is super economical considering the remote readability from the centralized base and the extremely efficient consumption of battery power. The base console / display, from which the local and remote conditions are observed, is powered primarily by the wall adapter and only uses battery power in the event that electricity from the receptacle is not available. Evaluating this kit from cost : features and performance ratio, it's a no-brainer winner. Excellent value excellent performance for almost 3 years in service.

This model transmits the 3 temperatures & humidity readings from our RV conveniently to the house, plus giving a temp and humidity reading for the room where the monitor is located. I use one transmitter in the RV refrigerator when getting ready for a trip. I know if the food is in a safe temperature zone... no quess work. We also monitor the portable dehumidifier in the RV by the humidity readings. This tells us when the dehumidifier is full and needs emptying. thus preventing the RV from getting moldy & musty. Thank you U Unni for quickly answering our questions and replacing a transmitter when it failed.

Update: Vendor sent me a replacement sensor. It seems to be working pretty good. I am raising my rating to 4 out of 5 stars. Bought this July 8, 2024 and it worked great for awhile. Sensor 2 started to show incorrect temperature readings over the last month or so. Now the Sensor 2 display is showing "LL" for the temperature. I'm not sure why it is doing this, nor what I could do to fix this. I assume Sensor 2 is defective but i'm not sure how to get a replacement. I left a message here on Amazon under my order to see if this can be fixed. I would hope this would last longer than 1 and 1/2 year or so.

Simple setup, needs Aaa batteries and Aa batteries, works, nice clear display.

A quality product. As for accuracy, all 4 sensor gave the same temperature when placed side-by-side. And It turns out my wife was right. It was 64°F in the house. I have officially lost the right to complain when she wears a parka, balaklava, and mukluks to dinner. Setting it up was a breeze. I stuck the 3 remote sensors on the porch, the garage, the back deck, and put the main unit on the mantle. Now, I have four sets of numbers to stress about instead of just one. It does take a lot batteries. No problem. I was looking into a second mortgage or perhaps wiring it directly into my neighbor’s Tesla. I decided to just buy some batteries, ordered them from Amazon, and used a forklift to move them into the garage.

After trying other brands with short battery life and short wireless range, I decided to take a gamble on this one. So glad I did because not only does it delivery longer range and battery life, but the temperature readings appear to be better calibrated and more consistent. I placed all 3 remote sensors on my desk, allowed 20 minutes or so to stabiize, and they all reported the same reading within a couple tenths of each other. It works so well that I bought two: One for home use and another for my business warehouse. At home I have one remote mounted upstairs, one outside on the front porch, and one downstairs in the basement, and they all work flawlessly with the base unit mounted on a wall in my kitchen. What's not to like? Yes I would buy it again.

I love the way it works and it is perfect with all the Temperatures. The colors are great on the unit. One thing do not put the sensor in direct sun light.

Love this little guy, works great, the first one I had to return it the the little arm that sticks out the back as a stand arrived broken off, so I ordered returned it and got a new one and it works great

Foctionne tres bien

Having looked at many weather stations and finding most of them overly complicated with cluttered displays, I was very happy to come across this amazing little weather station at a price far cheaper than most. I chose the multicoloured display and find it clear and easy to read. I plugged the display in using the USB cable supplied and put 2 x AA batteries in the outdoor sensor, within seconds the display connected to the sensor. No problem, no fuss. I attached the outdoor sensor to the fence in my garden about 30 metres from the display. The connection between the sensor and the display was strong and uninterrupted. I have compared the readings to my standalone thermometer and they appear to be accurate. I rarely leave reviews but I am so pleased with this product I had to let others know.

Display is very clear. Three different light modes make it convenient. The range is great, it works even through thick wall or even metal siding. The sensors are easy to set up and pair and you can even hang them if needed. I've had a lot of temp monitoring, but this is the best by a long shot. Simple, clear, accurate... Just perfect.

Einfach super. Die Sensoren sind einfach zu platzieren und liefern auch über weitere Distanz und durch Wände zuverlässig ihre Daten. Das Display ist groß genug, trotzdem nicht zu auffällig. Auch keine nervigen Farben und Symbole, keine leuchtenden oder blinkenden LEDs... weder an den Sendern noch den Empfängern. Für meine Zwecke absolut perfekt.
