Works only in Chinese Mi Home. A very weak Wi-Fi signal (in the next room already does not work, through the iron door most likely too). Quickly plant batteries (if and buy a similar wireless device, only on AKB 18650. Does not have an activation of the camera from the application. Absolutely pointless to buy without mi touch-screen smart speaker (important, Chinese version! Global connects only to Google and does not have on board 433MHz). It came in a Dragon Box, most likely there was already a return. (The current only supports linkage mi touch-screen smart speaker and mi frame TV 65.)
