TempAir Bluetooth Digital Hygrometer Indoor Thermometer of 260FT

I was kind of skeptical this would work given the price but it is amazing. It tracks the temperature and humidity in my greenhouse. I can check it from inside the house. It has allowed me to fine tune the heating in my greenhouse by monitoring temperature fluctuations over the course of the day. It is easy to use, was relatively easy to connect to my iPad (I suggest doing the initial set up with your phone, tablet or computer in close proximity. After that you should be able to check it from a distance.) The signal can’t be accessed from the front of my house (which would require the signal to pass thru a wooden greenhouse wall, an external porch wall and an interior house wall that is tiled) but if I move within about 20 feet in my house, it will update with no problem. For the price and functionality, I am very happy. It’s been running for about a month and has used less than 1/2 the battery, which given that it continuously tracks temperature and humidity, seems pretty good. It sits on a shelf in my greenhouse but also has a way to hang it from a nail or hook.

Love this little device. Just works out of the box, no app needed. It's nice and compact but it has a stand, a magnet, and a hanging hole. Worth the price just for the quality of the device alone but then it also has a great app. It's super simple to add it to the app and it doesn't even require making an account. And then it logs all of the data and it can be exported too. I love just having the raw data to do whatever I want with. The only potential issue is the lack of more advanced features such as backlight and on-device alerts but this same company has other models if you need that.

The TP357 is a good, inexpensive, consumer-grade thermometer/hygrometer. It has a compact display and also interfaces with an app via Bluetooth 5.0 / Bluetooth Low Energy (BLE) to view and export history and set alerts.The temperature sensor seems fairly accurate but the humidity tends to measure a few percent lower than expected. I have 2 of these devices and readings are reasonably consistent between them.The device can nominally store 1 year of history with a sampling frequency of 1 minute, but the memory is volatile and is cleared if the battery dies or is removed before data syncs to the app. The device is powered by a single AAA battery and that is unlikely to last a year so be careful. The ability to log history is fun, but it goes without saying, this is not your device for scientific data collection.The export function is nice, but the only way to save data is to email it from the app. Download to a file would be simpler and preferable, but this is really more a statement about the app than about the device itself.It's hard to complain for ten bucks.

excellent product. accurate. versatile. durable. longlasting.bluetooth range is great. i can see the temp on my ground floor, sitting in the basement.the temp and humidity alerts are invaluable. the charts and data export features are also very useful.i greatly appreciate that i can use rechargeable AAA batteries in this thermometer, and that it's not outfitted with that dreaded custom lithium battery that lot of electronics makers use that render their product a one-time use, disposable product.i've owned several thermopro thermometers over the last 5 years or so, with previous versions of the tp 357 and also their cooking thermometers. they have all performed flawlessly over this period. no issues at all. i'd give this company 10 stars for product longevity if i could.this product's excellence is only matched by the company's stellar customer service. the luxury of being able to speak to a live person in customer service is a rare one these days. but not only do you get to speak to intelligent, informed, technically proficient and friendly customer service people at thermo pro, they are very easy to reach - (no long hold times or complicated automated phone routines). oh btw the company is based in the US, as is the customer service which is a total bonus.in this day and age, its almost impossible to find longlasting, durable products. and to actually have easily accessible, responsive customer service too.... is just icing on the cake.

I love this TP357 temperature sensor. It is so much smaller than I expected though. I've had other versions in the past that were larger, so I think I was just expecting those sizes. I actually like how small this is. Seems perfectly efficient to show what it does in the small size. The other models have larger screens that show max and min data if you want that at first glance, but I just go to the app for the history. I also love that it has a magnet on the back in addition to the little kick stand.I used to have the old school versions with no Bluetooth, and would never go back. It's a game changer to be able to have a real time history of the temperature changes and the Bluetooth connection allows for quick review of all the data in the app. You can also export the data quickly and easily.The reason I love this one over the other new ones with Bluetooth is that it displays the temperature prominently on top and is also a larger font size display than the humidity number below. The TP359 version seems nice enough, but I hate that the humidity is displayed at the top. I constantly have to look twice because I naturally look at the top number expecting temperature. I don't know anyone that cares more about humidity than temperature. The temperature should always be the number displayed at the top of the display and I hope they update their other models to do this as well.

If you are looking for a humidity/temperature sensor or low-temp alarm device accessible from your phone, this is it.It is very accurate, has per 24/week/year records, and can alert you at a certain temperature. Very nice. The device is very small, as well, and comes with an optional metal magnetic backing so you can stick it on the fridge, wall, cooler, you name it. Very convenient.It connected flawlessly to the app at first setup, and only took about 2 minutes to do both. At this price point, the quality of this sensor cannot be beat. I am looking to get one for every single room in the house, as well as both sides of the basement. It is just too cheap and too high-quality to not just get more. If you are looking for something like this to help keep humidity levels higher in the winter and lower in the summer to adjust your run times on your humidifiers and dehumidifiers, this sensor is it.Will be buying more.

Love this thing being able to track everything in the app is so cool helps me figure out how to stabilize my temperature and humidity better than a normal temperature reader I have it in an egg incubator currently and it’s been so much easier to manage the fluctuations. Am gonna have to buy me a couple of these.

I got two of these so I could monitor the history with the app. Unfortunately, the app is mostly crap. Sometimes the app refuses to connect to the device. In fact, that happens almost every time and I have to sit and wait for a while for it to eventually connect. Also, when it does, the graphical chart is highly inaccurate. For example, inside the vehicle where I left one of the devices, the temperature in the vehicle never got below 80 degrees. But when I look at the graphical chart, it's showing a much wilder temperature fluctuation than what is actually real. Moreover, the humidity is all over the place. The graphical chart showing dramatic difference for something as simple as 1% difference between the two hours. It's quite poorly done.Worse, the app reminds you to update it every time there's a new update. Unfortunately, the update reminder stops the app from connecting to the devices, even if you hit cancel. So you have to manually connect them each time... else update. But what if I don't want to update? I hate updates and I hate being pestered to update things that already work well enough and I just want to be left alone.

Fácil de agregar a Home Assistant vía BLE y la integración ThermoPro. No requiere hub y es fácil de configurar en la app de Android.No tiene mayor funcionalidad que dar la temperatura y la humedad, con margen de error relativamente amplio (±0.5°C), pero ofrece una excelente relación calidad-precio.

I am not able to connect my thermopro device with the application. The app is not able to search the device.

Runs on AAA (good) not CR2032 (drain quickly)Good, clear displayGood accuracy.

I picked up this ThermoPro TP357 digital hygrometer and thermometer, and it has been a fantastic addition to the house. The Bluetooth connection and smart app make it incredibly convenient to check the temperature and humidity right from my phone.This is especially helpful for keeping a close eye on the indoor environment while I am proofing dough for Andrews Artisanals, as getting the humidity just right is key for a good bake. It is compact, the screen is very easy to read, and it updates quickly to reflect any changes. If you need a reliable, smart way to monitor the conditions in your home during the shifting Edmonton weather, this is a highly recommended pickup.

Do not buy shows random relative humidity readings within a fraction of seconds.
