ThermoProTP60 Digital Hygrometer Outdoor Thermometer Wireless Temperature and Humidity Gauge Monitor Room Thermometer with 500ft/150m Range Humidity Meter

I love this and it is my second one. No issues talking from transmitter to inside base unit for me unless batteries get low. I find myself looking at it constanly throughout the day. Nice sized display with easy to read numbers. I figure it is pretty dang close to what the TV station says temp is currently and they are 60 miles from me so it seems accurate enough, Get one you'll be glad you did.

It was as advertised. Very happy with it. Small size which suits me fine. I hung it on the wall, but small enough to fit, with stand, on the window sill. Once set up, read the directions, it works fine. But the batteries need to be put in in the proper order to synchronize. Like the wireless-no wire to run thru the window, so screen closes tightly.

The first problem will run into is that the battery compartment does not open in an obvious way, and the instructions are not helpful. I had to look at one of the user-supplied videos to see how it works. The tab of the battery cover that folds over the edge of the case actually pops up if you put your finger or the blade of a screwdriver under the edge of the tab. After that is is obvious.I ordered one with two sensors so it was a small challenge to figure out how to get them to both operate as they are supposed to. After powering up the main unit it took a few tries to get the remotes to both work. After removing and replacing batteries a few times and resetting the remote sensors by pressing one of the two buttons inside the back of the sensor I got them to both work.The details on the display are quite small and hard to read in dim light, but if you just wait, each remote will display sequentially, changing the channel about every eight seconds for however many remotes you have. The humidity accuracy is ±3% which is consistent with other sensors I have and is good enough. The temperature sensors are also good enough and the display size for Temp and Humidity are reasonably large (good enough to read from 8 feet away). The channel number and historic high/low and channel number are presented in something like a 9 pt font so get close or get a magnifying glass. Once you get used to it, you will be able to tell which channel you are looking at by how far the channel display is from the circular indicator below them. When I have it on a book shelf a few feet away it is easy to read. If I put it across the room the 3/4" high characters for the outside sensor are still readable while the 1/2" high characters for inside are a little hard to read (especially in dim light).The price was reasonable at ~$25 for model with two remote sensors. Long term reliability will determine my overall satisfaction and I will update this review when something happens after October 2024.The max/min function lets you choose whether you want to see the all-time high and low or just the high/low for 24 hrs (though there is no indication when the 24 hr period changes or re-starts).I guess the temperature and humidity trend indication might be interesting or useful under some conditions (like if I had one sensor in a greenhouse or cold frame) but I don't find that it adds much value for me. The range between the sensor and the central unit can be relatively large and it works effectively through multiple walls and floors, though I expect that the battery life won't be great. We will see. If I think it is an issue I will update this review.

This is the second ThermoPro TP60 because we are so pleased with the unit we purchased last year. We needed a unit in another part of the house, and the TP60 was perfect, with indoor and outdoor wireless temperature and humidity gauges. Easy to set up and mount. Small and discreet.

My recent purchase was for two ThermoPro TP60 wireless indoor/outdoor thermometer + hygrometer (humidity monitor) units, to add to the three TP60 units I bought a few months ago. Our house is multilevel and this arrangement lets us see the inside / outside weather in multiple areas around the house. Plus, in the colder months it’s super helpful to keep tabs on the humidity level in various rooms for health reasons.The ThermoPro set replaces a similar set of units by AccuRite, which started malfunctioning after years of service. (Hint: the weather app on my phone was reporting 100% humidity and it was raining outside, yet at least one of my AccuRite units was topping out the humidity at 70%.) The AccuRite unit featured a larger display on the inside unit than the ThermoPro TP60, but the ThermoPro displays are uniformly darker and easier to read from across the room.We are very happy with these unit pairs thus far, although performance over time is a key (and currently unknown) variable. Which brings me to my first pro tip to (hopefully) push the product’s longevity out further.Pro Tip #1: Each indoor unit comes with a button to change the wireless radio channel to tune to its mate. However, This button also enables you to do what I did: Use only one outdoor sensor unit (recall I have five) and tune all of the indoor units to it. Because outdoor weather is much, much harsher than indoors, I suspect the indoor units will outlast the outdoor ones. But if/when the single outdoor unit starts to fail, I can trot out one of my unused outdoor units, put batteries in it for the first time, and retune all the indoor units to it. This arrangement saves money on batteries and, again hopefully, extend the longevity of the whole system.Pro Tip #2: While you can place your indoor unit(s) anywhere in your living space as long as it’s out of the sun and not too close to a heat source, there is generally only one optimal place to put your outdoor unit.Placement of the outdoor sensor unit can be a challenge because it has to be somewhere that A) is always in shade during the day; B) has PLENTY of ventilation around it; yet C) is not so close to the building to skew the outside temperature reading when it’s cold out, b/c buildings always radiate some heat. The manufacturer generally recommends a low branch under a shady tree, which is where I put ours. But even a few minutes of direct sunlight a day can make your readings wildly off for that period. And if your spot is shady but too protected from ventilation, it can be like leaving the thermometer in a hot car — your readings can be inflated.I DO have two requests of ThermoPro, however.1. I would like to have been able to purchase the indoor and outdoor units separately, but was not able to figure out how to do so. The price of this set is quite reasonable, but less plastic and electronics in the environment is always a good thing.2. Please look into more environmentally friendly alternatives to the plastics you use in your products. And until you are able to replace the plastics altogether, please identify your plastic components with recycling numbers on the insides of the parts, so your consumers can dispose of these components responsibly. YES plastic recycling is currently a total sham perpetrated by large oil companies, but maybe our society can somehow start to do better with it than dumping it all in landfills and our oceans.Don’t forget to recycle your old electronics!

Good product. I like that it give temp and HUMIDITY both inside and out. Very easy to install - no wires to run and only on screw to do the outside. Easy to install new batteries.
