Great thermometer! Quite accurate compared to my aircon built-in thermometer (the difference is only about .2 °C measuring temperature around 25°C). The Bluetooth data syncing is a bit slow but it is all good as I only need to check the graph once in a while. It has both mounting hole, kick stand and magnet which can be used in different situations. It however does not have a backlight so it can be difficult to read it in the dark.

Had two for a few months in Texas heat and now in subfreezing temps. Put one in attic and one outside. Tested against existing thermometers and seem to work well. App on iPhone works well.

compared to an aranet4, which costs $170, the thermometer on the thermpro is actually very accurate. sadly the hygrometer is inaccurate by 5%, which is quite large. i hate to say it again but i guess at 10 bucks, it's acceptable. i just wish it wasnt the case.edit: i'm going to revise this rating to 5 stars just because it's only 10 bucks. hygrometer within 5% accuracy is ok i guess. it's very small and easy to carry with me on my trips. app is nice. i shouldnt expect too much. it is superb for what it is.

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.

This little gadget is super handy and easy to use! It’s lightweight, making it convenient to carry around and check temperatures and humidity in different parts of the house. The app (I use the ThermoPro Sensor app for iOS) is simple and works flawlessly so far.App Highlights:* History Tracking: The app keeps a record of all measurements and lets you monitor multiple sensors at once (take a look at the app screenshots I captured).* Custom Alerts: You can set individual alerts for each sensor (both temperature and humidity) on your mobile phone or directly on the device.* Data Export: Export up to 2 years of data in CSV format (with readings every minute) – great for tracking or analyzing trends.Accuracy:I’m not an expert, but I compared its readings with other devices (see photos comparing a thermostat for temperature and a humidifier monitor for humidity). It seems pretty accurate for the price.Battery Life:I've been using this device for about a month, and the battery is still nearly full.One Small Issue:It doesn’t measure humidity below 20% very accurately and only shows 10% or 20%, with no numbers in between.Overall, it’s a great value for the price and does a solid job for everyday use!

Excellent bluetooth thermometer, accurate and dependable. Works well with Android app, and at 50-75FT through walls. Highly recommended.

I needed a simple hygrometer to monitor the humidity in a large storage closet where I have my genealogy archive. The ThermoPro TP357 gives me accurate readings with the convenience of being able to check the conditions on my phone using the Bluetooth app. I like that you can set alerts for high and low humidity and receive alerts when they exceed the levels. The Bluetooth is strong enough that it can be read throughout the house. Finally, it uses a single AAA battery instead of a CR2832 disc battery, which is cheaper and more convenient to buy.

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.

Las mediciones se muestran exactas y la conexión con la aplicación es muy sencilla de hacer.El dispositivo es de tamaño pequeño pero la pantalla es de muy buen tamaño.Creo que es un buen dispositivo para medir la humedad en las habitaciones. Sí lo recomiendo.

El termómetro e higrómetro son precisos y funcionan a la perfección. Las medidas son exactas y fluctuan adecuadamente conforme a la temperatura y la humedad. El tamaño del termómetro es pequeño, portatil y ligero. Los números son legibles a una distancia relativamente cercana.La aplicación es facil de usar y se empareja con el termómetro en segundos. Las gráficas de temperatura diaria, semanal, y anual son exactas y muy útiles.No tiene luz propia y no se puede leer en la oscuridad. Pero se puede consultar la temperatura a cualquier hora desde tu teléfono.Es el segundo que compro.

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.

At the end, it is all about how it fits your need. For me it was worth the money and I even bought another device like this for around the house.It ended up saving me time and allowed me to get value out of it from the start. The money was well spent, and the device performance is acceptable so far. In the past I was hesitant to buy these type of devices because of cost. I was lucky this device does what it advertises (long battery life, up to 1 year log storage, small size, and a commonplace AAA battery type.My use case is to track humidity and temperature for filament used for hobby 3D printing. I wanted to build the device myself (temp, hum, and pressure, all read over BLE, with an e-paper display and all!), but as time went by, I could not find the time to finish my 'project' within budget and hobby-time constraints. This device allowed me to start tracking filament use/storage life today, while I could still keep dreaming of my own device (because this product does not sense barometric pressure). Now that I use it, I dream of using a raspberry Pi to read this BLE device automatically (yes, adding another project to my pile of 'unfinished projects')My only downer so far is that the Android app does not allow me to save or export the data. It is not even available in the user space memory of the phone, so I can not easily extract it from the app. While I can see the plots in the app, I want to be able to save all the data to a file for later comparison. I will need (yet) another project of mine to use a Raspberry Pi to read all the data and save it. It would be nice if they update the app to at least save all the data to a file in the Android app folder, so we customers can copy it.Hope this experience helps others.For some of the comments I read, I think I know some of the answers:- The location access the app needs is because Google improved Android security awareness, and since Wi-Fi and BT/BLE scanning can be used to locate your device, the message will say 'location' because the app you are trying to use needs access to the BLE scan function to be able to find any of these sensors you own that are near your phone.- The 10s refresh-rate should be independent of the speed at which the sensor stabilizes to the exposed environment (response-time). I agree the manufacturer is pushing the limits of misleading by stating "10 s Fast Response" where 'response' and 'rate' are not quite synonyms. In any case, typically these devices take some time to settle due to lack of proper air flow, etc.
