I like the small size of this outdoor motion sensor, it readily connected to the YoLink hub and was fairly easy to set up in the app. My storage shed, in back of the yard, is where it's placed and it still has a strong signal all the way to the hub located in the house. The push notifications come through to my phone immediately when motion is detected along with a voice notification I set up with Alexa. The water sensors, I purchased from YoLink, have been outstanding so I figured I'd give this motion sensor a try. The only minor negative thing is the way it attaches to the wall or ceiling. The sensor is supplied with a magnetic disk which in turn is attached to a wall or ceiling with 3M tape. The sensor seems to slide down the magnetic disk slightly when attached to a vertical wall but did not fall off. Hopefully it will stay where it's put!
