TempPro TempAir PLUS TP65B Wireless Indoor Outdoor Thermometer & Hygrometer — 4" Touchscreen, 500ft

***Edit/Update: 11/24/25This 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.

So far, so good

Replaced an old tempo works great.

Excellent - easy to read, nice and clear

This is my second TP65B. The first lasted >5 years before getting funky. I like this unit because it has a decent range for the outdoor sensor.

I ordered the TP65 to replace the remote transmitter on our LaCross weather station. That unit quit working after at least 15 years outdoors. The TP65 cost less than a replacement transmitter from LaCross, and it reports the same two functions: temp and relative humidity.I set it up according to the instruction in the owner's manual which was to put the batteries in the remote sensor first, then into the base station. OK, but I got no response from the remote. I tried all the suggestions in the manual, to no avail. It was pretty frustrating. By this time it was 7 pm on a Friday night. I saw that customer service was open until 8pm. So I called and got right through to a guy who knew just what the problem was. He told me to take all the batteries out of the units and reinstall into the base station first, then the remote, just the opposite of what the manual called for. It started working immediately, while I was still on the phone. The customer service guy said that the manual is written for cases where there are multiple sensors. So wouldn't it be easier on the customer to make that clear in the owner's manual?The unit has been working perfectly for over 48 hours now. What pleases me is that the indoor and outdoor temp readings match all our other thermometers, including a US Navy mercury thermometer outside. All the readings on three other thermometers are within less than one degree variation, often being exactly the same. I can't ask for more than that. I would recommend the TP65.Update June 2019: This unit is still working perfectly and staying within one degree at all times with my US Navy mercury thermometer. We are very pleased with the TP65.

As I am outdoors for hours on a regular basis you can't always determine the temperature with a glance to see how people are dressed. That said I rely on a real time thermometer. There are many of them which are junk. This one is not. The product was well designed and packaged. It is evident thought went into the little items such as battery compartment access. I am of the opinion it is high quality for a fair price. The setup was very straight forward, and it took about 15 minutes for the outside sensor to settle into it's temperature. While it was "dialing in" on its temperature, which was cold, the unit accurately displayed "trending down" for the temperature. Having read another positive review for the unit, the only pseudo negative comment was the battery failed in very cold weather in a few weeks. That user installed lithium batteries and was satisfied. I followed that advice and installed two lithium batteries for the outside sensor to avoid unnecessary problems to replace batteries in bitter weather. Having used the unit for a while, although the numbers on the display are not as "tall" as some others, they are "BOLD" print font and very easily read. Regarding accuracy I have another digital thermometer, and the two of them register within one tenth of a degree. More than accurate to determine whether or not bundle up.

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!!! HahahahaI 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.

I'm actually going to take a bit of time and write a review, because I really think this product deserves it. I've only had it for around two weeks, but so far, so good.I got this wireless thermometer for a bit of an unconventional purpose; as a wireless way to monitor temperature and humidity (mainly humidity) in my Crested Gecko's vivarium. The setup I have really doesn't allow for devices with cords/probes, and reviews for thermometer/hygrometers that were actually made for pets were pretty dismal. So, after seeing this new ThermoPro product with great reviews, I decided to give it a try (my gecko has a pretty big viv and he loves exploring new things, so the addition of a small sensor wouldn't bother him).The outdoor sensor seems to be working great thus far, no major erratic swings in readings at all (unless I do something to make it change, like misting the viv). It's waterproof, but you do need to have it upright so that water doesn't enter the sensor at the bottom. It has a little hole at the top that I threaded a paper clip and string through so I could hang it on a vine. It also has a bright red light that flashes every 30 seconds or so when it sends data to the main monitor, which I worried might bother my gecko, so I carefully covered the solid plastic and red light with dark painter's tape, leaving all the sensors and compartment-opening-points still exposed, and now the light is not noticeable at all, unless you're really hunting for it at just the right angle. Adding the tape did not affect the temp/humidity readouts at all; they stayed the same after applying the tape as they were before.The main readout monitor itself is really nice. It took me a few tries to really get the hang of the controls, but since there's only 3 buttons to tap, it's not that hard. Touch screen is hyper-sensitive, and the backlight (which I thought I would never use) actually is handy since it's positioned in a room that gets hardly any light after sunset, and the numbers can be hard to see if I want to check them in the evenings. But this room is exceptionally dark; the contrast on the readout is more than enough to be easily read in a normally-lit room.As far as accuracy goes, I have to say that it is accurate simply because it says the same things several of my other gauges do. I have one mercury-style thermometer, one analog thermometer, one thermometer/humidity laser gun, and one analog hygrometer. Between all those devices, the numbers really don't change. If anything, I would say my temp gun is the least accurate, but only because it isn't measuring the temp of the air, but the temp of the material it's pointed at, which varies greatly. Therefore, its accuracy is not quite in the same category. At any rate, I just got up and checked all the gauges, and they're identical to what this ThermoPro wireless device says. I find it hard to believe that so many different devices could all be wrong in the exact same way, so I believe this one is accurate.Setup was fairly quick and simple, and took way less time than the directions indicated; so much so that I set it all up twice just to be sure I did it right the first time. Same results, so it looks like it's all correct.All in all, it's shaping up to be a great little device, and I'm glad I got it. It gives me peace of mind to know that everything's the way it should be in my gecko's home with just a quick glance at the screen (which I placed on a nearby bookshelf), and I love knowing the temperature/humidity of my own home, since I did not have any sort of fancy thermostat before (old baseboard heating). I also like knowing that multiple sensors can be registered, so if I ever want to actually put one outside, I can get one and easily do so. If anything changes, I will update this review, but as of right now, I am very happy with my purchase. :)
