ThermoPro TP55 Digital Indoor Hygrometer Thermometer, 4-Inch Temperature / Humidity Monitor with Touchscreen and Backlit, Indoor Room Thermometer / Humidity Meter for House Home Greenhouse

This unit was smaller than I expected it to be, but actually it’s plenty large enough for its purpose. Digits are easy to read. I installed the sensor outside underneath my deck, on one of the upper boards. Then I put the display unit in my kitchen, only about 12-15 feet away. At first I placed the display unit on my fridge using the magnetic backing, but when I did that the display disappeared. It says somewhere in the manual that putting it on a metal surface with the magnets may cause it to have problems receiving the signal from the sensor. So a no-go on that. I put it on my counter top and it receives just fine. The external sensor I just hung on a nail. VERY easy install!!! Hahahaha I like how this unit gives a readout of temp and humidity for indoors and outdoors, and also a “trend line” for each - is it rising, falling, or remaining fairly steady? That’s nice. Also, the readout on mine seems to be pretty accurate. Be aware that when you first install it, it will take some time (maybe 30 to 60 minutes) for the display to give accurate readings indoors. Takes times for the sensor to adjust, I guess. Ever since that initial period it’s been spot-on. Before looking these up on Amazon, I had no idea that these things even existed!! That is, external sensor sending wireless data to internal display unit. That is so cool!!! And amazingly inexpensive too. I’m so impressed, that after I do a residential move in the next year, I plan to get one of the higher-end weather stations, that does it all - temp, humidity, barometer, wind speed, rainfall amounts, etc. THAT will really be cool!!! But for now, this little device works just find for my needs.

It’s small so it can be taken around easily. I like that it has magnets and a stand, so you can use it however you like. It works well, quality is good, doesn’t feel cheap. Love the backlight that’s allows you to see the temperature in dark rooms or at night. I’m still not certain about the accuracy, I got this because I wasn’t sure about the other thermapro thermometers I had, but it doesn’t feel like it’s accurate. I’ll have to do some more checks. Other than that, it does what it’s supposed to do and looks good too. No alerts yet, still using it for now.

***Edit/Update: 11/24/25 This is a new added unit to my old one that was a workhorse for many years. I had to add one for the home with a new remote sensor because the old one got soaked in water. Nobody’s fault. Still a great unit, fired right up. Really like this touchscreen thermometer! Definitely worth it! Original post: What a great hygrometer! I must say that after reading a whole lot of negative reviews, I was a bit apprehensive about buying this meter. There are however a few that spoke very well not only of this model, but also excellent customer service. And I agree 100%. PROS: Honestly it was a BREEZE to set up, though just to be sure, I watched the video tutorial posted under the listing. I did decide to use quality lithium ion energizer AAs to gain better life and stability in extreme temps. Once the batteries were installed, the remote unit paired right up with the base station. No fuss, no issues whatsoever. *Note - Yes, the battery tray on the indoor base unit looks counter intuitive, but it’s not difficult. As with any electronic gadget, it is wise to be gentle! Signal strength- Amazing! I haven’t walked the actual distance with a measurement device but I set the remote sensor around twists and turns, walls and load bearing structures to place out of direct sunlight in our front door walk area. I’ve tried every room in the 4BR home with zero signal drop. The only way I got it to “force” drop was to take it across the home & out to the furthest part of the backyard patio. (Far beyond 300 feet) No problem reconnecting with the base once it’s back in range either! It just automatically links up. Accuracy: What are the negative reviews about?? I’ve tested it from lows & highs, relative humidity with weathermaxpro and National Weather Service, and it is near identical to reports. Well within any degree of +- Id ever have use for. Talking <1degree, and that is subjective as temps vary from the tarmac where local temps are taken here in AZ. The rel humidity is spot on, and yep I’ve got a pro level Air Quality Meter that I cross referenced it with. I’ve set the remote sensor in different rooms, under sinks, front and back - all of which proved to me that I made the right choice in this purchase. Touch Screen: I haven’t even removed the clear protector from the display and it’s still easily tactile. I didn’t expect that being spoiled by pricey Retina displays. It’s designed well, very user friendly, looks sharp, and most importantly, it WORKS! CONS: None thus far especially at this price point. Of course I’ve only had it set up running 2 weeks. So if any fails or glitches, I’ll update this review. We have a very hot summer ahead as well as the monsoon season which can be especially hard on the little things. Note: I inadvertently hit send before I finished and added photos. So I’m doing that now. 👍 Re +- value between the local posted by Living Earth, it should be noted that we live higher elevation near the mountains so it’s to be expected that a few degrees cooler. The rel humidity in the bedroom is higher bc of a cool mist diffuser I use w essential oils for dry sinuses intermittently.

من يوم مااشتريتها مااستفدت من القطعه الخارجي غير شغاله وغير فعاله يجب ان تلصق القطعتين بجانب بعضها حتى درجة الحراره الخارجيه يتم قراتئها وهذا الشي غير عملي وغير فعال كيف احصل على درجة حراره داخليه وخارجيه اذا!!! السعر مبالغ فيه

Great quality thanks

Buen producto,

Vivo en costa y con una humedad muy alta. Lo uso para controlar los niveles junto con mis deshumificadores.

Excellent Hygrometer and Thermometer. It seems to provide a very reliable reading. Batteries come included. The temperature readings can be changed between Deg F or Deg C. I like the magnet at the back that makes it installing easier on a mettalic surface e.g. a fridge door.
