Xiaomi Mi Temperatur- og Fugtighedsmåler

I use it when travelling , like to know what the room temp actually is

I bought 3 of them for monitoring the home temperature. Small, it has good accuracy and clear LCD. Unfortunatelly it supports only Mi Home application and it does not support Alexa, Google or Apple Homekit and this makes useless for me this product.

I have one in each room, which helps to adjust the heating and the dehumidifier. A must-have for those who live on the ground floor :)

It seems accurate but it's worth noting just how small it is. Fine if you're connecting via Bluetooth to see readings on your phone or whatever, but not great if you want to be able to walk into a room and glance at it. I've taken a picture of it with a 50 pence piece on top for scale. Also worth noting that as others have said, it does not come with a battery.

I bought sensor on the Amazon prime days for 6.99 and for that amount of money it is amazing equipment. I should buy 3-4 because it is working very well.
