This little sensor offers a lot for it's price. It can measure room temperature and humidity and based on the measurements it displays a smiley that suggest how comfortable the environment is. It can be connected to a smartphone via bluetooth and then one can use 'Mi Home' app to see the sensor data. I had no means of testing the sensor accuracy, but from my observation and by reading the reviews it seems that it's pretty accurate.

I wish there is a way to customize the display a bit through the 'Mi Home' app. For example, remove the smiley and rather display the humidity alone (and maybe in bigger text) or the current date and time maybe.

In general, I'm very pleased with this little sensor and I warmly recommend it.

Preso da tenere in casa come termometro da affiancare al tradizionale, che ho in altra stanza. Le misurazioni sono accurate e precise. Anche per l'umidità.. testato mettendolo in frigo e fuori casa in ambienti umidi e i valori cambiano pressochè immediatamente. Esteticamente anche molto gradevole e di ingombro ridottissimo. Arrivato in 20 giorni. Consigliato anche perchè qualità Xiaomi. Unica pecca la mancanza di un tasto per tarare lo schermo.. e farlo più o meno marcato a seconda delle necessità. Molto comodo anche l'adesivo da attaccare dietro per appenderlo, non scontato.

Great !! Using this two weeks now and it shows accurate temperature and humidity. On several cold days, I compared it to the digital wall thermometer that runs my heating/cooling system - it read exactly the same when I placed it close by. I tested the humidity gauge by taking it out of my bedroom which was showing only 25% humidity and on a rainy day I placed it on the floor just inside an open door to my deck. Within a minute the number began to rise until it reached 85% so I know it is working. Hope it continues to work this well.

For my use, I just wanted to know humidity in my shop and temp in the garage (for fluids that might freeze) and this is very nice. The display is nice and large to read from a distance of 3 to 6 feet. It's always between 45% and 60% depending on what the air conditioner can keep up with. Which seems reasonable. Easy to use. It stands up on a level surface or can be hung on a wall. Delivered quick and well packaged. I hope this unit will last a LONG time.

One of the best Temperature Sensors of the web.
The Design and the simple Interface is an epic experience!!
The only negative thing i have to say: The Xiaomi Mi App can't find and include the sensors when you're in Germany....
The only way to get it to work with Bluetooth is when u set ur Server to China. when u do this u have the Problem that u can't manage ur Devices which u have on the German Servers...
I hope it will get updated. It's just an software and rights issue

They are acting fast and quite precise, i love them. even without Bluetooth working correctly ;)
