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.

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.

Have got a total of three of these now, and was initially using them with the Mi app and that worked perfectly.

However, I needed more and wanted to be able to read temperatures while I was away from home so I was glad to find they are compatible with Home Assistant running on a Raspberry Pi 4. A few months on and I've flashed them with a custom firmware so they report the temperature into HA every 120 seconds (default firmware is 10 minutes) and I've coded my own bit of YAML to use them to control the WiFi connected heaters around my house, via a simple Thermostat interface.

All in all, very happy with this product. Just note they do n...view more Have got a total of three of these now, and was initially using them with the Mi app and that worked perfectly.

All in all, very happy with this product. Just note they do not come with batteries and you'll have to buy these separately.

Don’t forget you need to spend another 70 bucks to connect this with Alexa. After you connect this you understand it’s uselessness as Alexa can’t use readings in routines.

A great little device that comes a with double-sided sticker but I wish there was a better way of mounting it on a wall to make it easier to remove and put back, like when you have to change the batteries.

Works as indicated. Handy to know the temps and humidity in the house. Been using it for 3 months now and loving it. Works as indicated. Handy to know the temps and humidity in the house. Been using it for 3 months now and loving it.

For a small device like this it will surprise you how much information you can get plus setting up a smart home this is one of the gadgets to get! For a small device like this it will surprise you how much information you can get plus setting up a smart home this is one of the gadgets to get!

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.

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.

Battery lasts just a few weeks. I threw it in the bin. Battery lasts just a few weeks. I threw it in the bin.

Love being able to get a real reading on the temperature and humidity in my room. I know if I should turn on the heater or not and when to turn it off.
