I have used these for years and the Bluetooth option is new to me, but I love it! Since I live in a house with multiple levels, I can leave one upstairs and see on my phone if I need to turn on the air conditioner to cool the upstairs before going to bed or not without actually running up and down the stairs, which I have a hard time doing now. They work great they last for quite a while and I will definitely be replacing others if they go with the new Bluetooth version. I sometimes keep groceries in the garage in the cool weather rather than in the refrigerator and having one out there would let me know if the garage temperatures get too freezing where I need to take food in so it doesn’t freeze also. I can think of so many reasons to use these. The two I bought I think are only going to be the start. They also have a lighted display, but you have to touch them to get it to light up and it does take a minute after you do, but that makes so much easier to read. For the price I think they are well worth it.

At first I wasn't so sure about these... they didn't read correctly. Changing out the batteries to a better brand made all the difference in the world. Now the themometers work great. I just ordered 2 more. It's really nice to be able to know that the greenhouse or my feral cat house is holding a good temp in cold weather without going outside to check. So I definitely recommend the ThermoPro, just don't use the included batteries.

This is a great little gadget for the user to monitor indoor temperature and humidity. I live in a humble cabin in the Northwoods of Minnesota. The half the year where I don’t use the infloor heating system, and the system is turned off, the ThermoPro provides both the temperature and humidity readings. The unit itself can be mounted via its magnet or used on a table of the users choice. I’ve been using the device since late August, and look forward to the humidity readings this winter, because at times, the dryness inside the cabin leads to some pretty intense static electricity shocks, where one of the dogs is cautious around me. Great little product for temp and humidity readings.

This is a really cute, well designed hygrometer and thermometer that lets you connect multiple units to your bluetooth device. Out of the box all you have to do is pop the batteries in and it will start working. There is a nice magnet on the rear that lets you mount it on a fridge. Alternatively you can use the leg bracket on a flat surface. The most surprising aspect to me was the ease of setting it up on an app. Download the app, tell it to find a new device, and you are done. Even the easiest consumer home cameras are way more difficult to set up. (I can't tell you how many times they fail to detect the device through bluetooth). Can't rate battery life yet, nor accuracy.

Accurate, cheap, and hassle-free. The TP50 updates every 10 seconds, shows min/max and a simple comfort icon, and its magnet/stand make placement easy; mine matched another calibrated meter within ~2–3% RH and ±1°F. The “Classic” model lacks a backlight and any app/logging, and the small display can be hard to read from far away, but for dialing in a room, closet, greenhouse, or pairing with a dehumidifier, it’s excellent value.

This does what it needs to do! I bought this in September of 2022. I put one AAA Battery into it and let it roll. That battery finally died today in November of 2025. So, 3 years of battery life with one battery. Not too shabby. I suppose I'll replace the battery now.

It’s simple, accurate, and doesn’t take up much space. I like to keep my eye on the humidity and temperature in our finished basement - especially during the summer months. I don’t really trust the reading on the humidifier because they make those things so darn cheap anymore.

Put these in both of my kids rooms to check and make sure the temp was comfortable for them. It was super easy to connect to my phone via their app and the battery has lasted a long time! I also love bringing them on vacation so I can know exactly how to dress my kids for sleep in whatever room they’re sleeping in!
