ThermoPro TP357 Digital Hygrometer Indoor Thermometer of 260FT, Bluetooth Thermometer Humidity Meter with Smart App, Room Thermometer Humidity Gauge with Temperature Humidity Sensor | Humidity Meter with Smart App, Room Thermometer Humidity Gauge with Temperature Humidity Sensor

I currently own 6 of these, and use them throughout my house to monitor the temperature and humidity. I have taken detailed pictures of the monitors, their accuracy, the instructions, and the Customer Support contact information for anyone who has lost theirs. Accuracy: These units are as accurate as they claim to be, which is + or - 1 degree of the actual temperature. That means if the actual temperature is 70 degrees, it may read anywhere from 69 to 71 degrees. Honestly, this is close enough for the price and its intended use. I have 6 of these, and all of them are within the rated accuracy of one another. Size: These units are fairly small, but the LCD display is large enough that I can read it without needing my reading glasses. The Temperature reading is 1/2", and the Humidity reading is 3/8". Smart Home: These sensors will work with Home Assistant, and possibly other Smart Home monitors and controllers that use Bluetooth. This is a HUGE plus for a lot of people who like to play with IoT devices. Battery Life: I use Eneloop AAA rechargeable Ni-MH batteries in all 6 of my monitors, and they last about a month or 2. Honestly, its not often enough that I know exactly how long they last, but I don't have to recharge the batteries very often. If you use Lithium or Alkaline batteries, they will last a lot longer between battery changes, but the batteries will cost more in the long run. The App: The app is a great, and well designed. It is intuitive, so you just touch most things on your screen to see more details or to change a value. The app will quickly find any units that are powered on within range that are not yet adopted, and you can rename each unit so you know what/where it is. You can change the temperature scale for the display to either Fahrenheit or Celsius. By clicking on one of the monitors in the app, you can see the history for that monitor for the past 24 hours, 1 week, or 1 year. The app will also display the Heat Index based on the Temperature and Humidity readings. You can set alerts in the app for both a high and low temperature or humidity reading. Mounting: This unit has 3 ways you can set it up; a magnet on the back, a kickstand, and a keyhole for wall mounting. The stand is self-explanatory, and the angle is great for readability. The keyhole on the back allows you to hang it on a wall with a nail or small screw (not included). The magnet is great for anywhere with a metal surface like a fridge. You can also use the magnet to attach the unit to most corners in a house with drywall. There is a metal edge on every outside corner in a house with drywall, and the magnet is sufficient to mount on these metal corners. In the picture of this method, you can see the monitor mounted on a wall corner, and if you look closely below the monitor you can see the metal edging showing through where the paint has chipped off. My Wishlist for this product: I would love to see a version that uses WIFI and Cloud so you can monitor from anywhere, not just when you are in the house. * A backlight with a small button to activate it would be a great addition to these units for night viewing. * A stronger magnet would be appreciated.The magnet on the device is ok, but even a slightly stronger magnet would make it much less likely to fall or be knocked off unintentionally. * I would love to see the ability to calibrate the temperature reading if it is off. I would definitely be willing to pay a little more for this feature.

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.

Great product. Compact and works well in room for Baby. Has the smiley face when temp and humidity is at comfort level for baby. Connects to iPhone as-well so you can check it through Bluetooth if you’re not in the room when baby is asleep. Deffinately recommend!

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.

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