Temtop Humidity Meter T1, Indoor Thermometer for Room Temperature, Bluetooth Hygrometer with Notification Alerts, Data Export, Digital Gauge for Home, Office, Greenhouse, Garage, Baby Nursery, Gift

I love this little guy for accurate temperature. Accuracy readability and functionality are good. Magnetic strength is perfect, no weakness in the magnet. Come to the small short charging cable to charge the chargeable battery. My unit the t1 was fully charged when I got it. Display size about 3 in. External kickstand attaches magnetically very handy 2 different options available. Or you can go without just standing on the edge. Not sure the battery life it's supposed to go 180 days theoretically we're having so much fun we got to put the review up before we get to 180 days, right. Excellent little temperature box also shows humidity I'm not sure if the accuracy on that it stays between 24 and 36 so far. Able to turn off and on by holding it for 3 seconds on the power button. Extremely mobile to carry in your pocket on the go if you wish. I'm not sure of the battery life but it does require a rechargeable built-in no batteries needed. I sent a text to ask for how to change the clock so far no information on email. Was able to sync with Bluetooth using an app but it never told me the temperature or humidity on the app so I'm not sure if it was working or not. most likely not working yet. I love this little guy, he's cute.

I make dtf transfers for myself and others. Room temperature and humidity are a critical part of the process. This item is portable and very accurate. If you are making dtf items, this is an inexpensive and critical item you need to have.

Works great. The app is a bit dated looking but it works for what it needs to do. It’s a good value for what you get. Connecting it to my WiFi and Bluetooth took no effort at all. I do wished it had a backlight on the screen, but I guess the battery would drain quickly then.

I cannot tell you why I bought this, but I will tell you it works very well and helped me figure out something in the workplace

The app was just updated and is significantly worse. Once connected to the device, you now have to click another button to actually get the historical data from the device instead of it automatically loading. Also, the temperature history refuses to show the temp in Fahrenheit now. Add in the fact that I didn't realize this had no Internet connectivity - you have to be within Bluetooth range to get the data from the device. Plus I got another Temtop device that tells me CO2, temp and humidity. The humidity readings are 5% different between the two.

In our line of work as mitigation specialists , accurate environmental readings are crucial. As a mitigation company, we often need fast, reliable data on indoor conditions, and that’s exactly why we added the Temtop S1+ to our toolkit. We’ve been using the S1+ for about a month now across multiple job sites — both in homes and commercial properties — and it has quickly become a valuable part of our inspections. It’s portable, affordable, and most importantly, it delivers consistent PM2.5, temperature, and humidity readings without any unnecessary complications. The fact that it also provides an AQI reading (based on PM2.5) is a bonus when we need to quickly communicate air quality concerns to property owners. While it’s not a full EPA-grade AQI monitor, it’s extremely effective for what we need in the field — quick snapshots of indoor air conditions to help guide our next steps in mitigation and remediation. It’s lightweight, fits easily into our daily gear, and the battery life has been solid even with frequent use. Given how few portable air quality monitors are on the market — especially ones that are this reliable at this price — we’re really impressed. We plan to keep using the Temtop S1+ for quick assessments, and it’s something we would recommend for other restoration or mitigation teams who need fast, reliable indoor readings without breaking the budget.

Great product! I love the Bluetooth connectivity that allows me to check the humidity inside the pelican cases that I use to store my cameras. The device seems to be well built and the screen is colorful and clear.

It works, tells you the temp but never updates in the app. I paired it, it work the first time. After that, the app says it disconnected. Paired it 5 times, but does the same thing. I bought it for its Bluetooth/app capabilities but it’s horrible at that. I hate this thing. Waste of money.

Good product
