Neat to have an idea of how hot the rooms are getting around the house. Without a central hub we can't collect data over the web from them, but when near them we can use bluetooth low energy to read them from our phones, and they store a bit of history so we can see how the temperature and humidity have been changing throughout the day.

I was fed up with analogue hygrometers in my humidor as I never found them as accurate as I'd like and the specialist humidor digital ones are expensive in NZ.
Thought I'd give this a go, even though I was wary that there is no way to calibrate it. Needless to say, I was pleasantly surprised, and when given the salt calibration test, it read 76% right out of the box! To put this into perspective, 75% is what it should be, but this particular hygrometer states that it has a ~1% variance so I was happy, so this meant that it was performing as promised.

I've only been using it for a day so far and we'll see how well it holds up, but for $15 ...view more I was fed up with analogue hygrometers in my humidor as I never found them as accurate as I'd like and the specialist humidor digital ones are expensive in NZ.

when i bought it i wasn't aware that also works with Amazon Alexa, today after placing the unit next to my heat pump control Panel, i got a notification from Alexa that a new device was installed automatically, so I asked Alexa, what is the temperature in the Control Panel (name i gave it) & Alexa would tell me the Temperature.

Beside being able to see the Temperature from my phone through the MI app, now also have the option to ask Alexa for the temperature, still not sure what else can be done with Alexa.

NOTE: I also have a MII hub / gateway (Xiaomi Gateway 3) , not sure that has anything to do with Alexa recognizing the unit. when i bought it i wasn't aware that also works with Amazon Alexa, today after placing the unit next to my heat pump control Panel, i got a notification from Alexa that a new device was installed automatically, so I asked Alexa, what is the temperature in the Control Panel (name i gave it) & Alexa would tell me the Temperature.

We always wanted a simple temp and humidity monitor in our living room. This little guy does the job brilliantly, without breaking your bank. Highly recommended.

It's a small device and keeps track of temperature. It keeps a history as well, which can be accessed via Mi Home app. It's a small device and keeps track of temperature. It keeps a history as well, which can be accessed via Mi Home app.

Useful to have, with out of range warning. Useful to have, with out of range warning.

It is finished in high quality workmanship. It is working accurately and easy to read. It is finished in high quality workmanship. It is working accurately and easy to read.

The temperature display is fairly accurate but astonishingly slow to respond to changing temperature. The humidity display is consistent across several units but is very different to my traceably calibrated Vaisala humidity probe.

Excellent product. Excellent product.

Works as advertised, great value Works as advertised, great value

very happy that it does not require an app and WIFI to function! very happy that it does not require an app and WIFI to function!

Connects to the Xiaomi network, good range. Device is smaller than anticipated. Connects to the Xiaomi network, good range. Device is smaller than anticipated.
