TempPro TempAir ELITE TP357 Bluetooth Indoor Hygrometer & Thermometer — 260ft Range, Instant Alerts

I love that you can see the temperature on your phone.

I bought this to keep in the trunk so that I can be sure my groceries stay cold, or soft drinks in the cooler don't overheat, etc. The app downloaded right from the QR code in the manual that came with it and paired with my phone instantly. The thermometer even comes with a battery. The app has temperature and humidity alarms you can set, and stores data for up to a year, plus the graph in the app shows min and max values automatically. I'm super impressed for such a low price. It's built solidly, and is small enough to use about anywhere. If you register your order number you get 3 more years of warranty! Just discovered that while I'm driving I can say "Hey, Google, open the ThermoPro app" and it pops up on my phone screen and updates automatically, so I can check the trunk temperature while I'm driving. Highly recommend!

This little thing is awesome! I replaced a ThermPro unit (which still works great) with this one. This one is much smaller, and it connects to my phone via Bluetooth, which is very handy. I use it in my humidor and it works perfectly. I highly recommend this.

It works perfect lmao only thing is i was expecting it to be bigger than my phone and its smaller than a beeper

Work great. Wiah there was a way to change the name for each unit.

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.

Extremely fast replacement time replacing a sensor that didn't work great communication

This is a great option if you need to check your blood pressure as I was requested to do by my doctor. I test every morning and it seems to be working as desired. I love the Bluetooth connection to the phone app so it keeps the history and data I will be able to show during my next appointment. Quality seems good and so far it is working for quite some time on the first set of batteries.

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.

good item.

Using to monitor temps/humidity in crawl space prior to encapsulation, to see how much difference there is after encapsulation

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.

Bought a few and was so pleasantly surprised how much I liked them, I purchased some more. Just a simple little thing but it works great, and even comes with a battery. The App that goes with it is fabulous too.. You can see all the info easily and can export it.
A NOTE re: the BATTERY - for those ppl having trouble with the included battery not working, make sure you take off its plastic covering before use. It's really thin and hard to see that the battery even has a plastic cover all over it. Would explain why so many are complaining about it not working.

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.

How often does anything just work right, the first time, right out of the box?These do. I'm currently running 16 of these and plan to add more as necessary. They are all usually within 0.4 degrees of eachother and their humidity readings lined up well as well (I just can't recall the spread).The app just works. It's super easy to add more units to the app, and they always just connect, download their stored data and bam, your good to go.Only one downside, their battery life is comparatively short,running through a single AAA every few months. They warn you too. If the battery runs out, no big deal, it stops reporting data but a battery change and your up and running again. No need to connect the device to the app again.One of the best little devices and apps I've found. Genuinely pleased and would recommend them to anyone who needs a good hygrometer/thermometer.
