A month ago I noticed a new switch and Aqara temperature / humidity sensor, the devices were to cooperate with the Smart Home system from Xiaomi. The switch has already reached me, but it does not work with MiHome, it needs a separate application "Aqara". I downloaded apps from the App Store, to create an account you need to enter your phone number and wait for a return SMS. I waited for 48h code did not come, I tried in two networks, SMS with the code did not arrive. The switch is useless, it can not be used. Do not buy a new one square versiononly older round switch! With the temperature sensor it may be similar, on days it should arrive then I will confirm.
Update, the switch is already connected to Mi Home and you can control other devices.
