It is really useful and can help you turn on or off the light in the action. Works with SONOFF ZigBee Bridge in harmony, you can set a scene to get your hallway lighted immediately when the door is opened. The camera function can be enabled on the sensor page in the eWeLink APP, which also allows you to view clearly who enters your home even you can frighten the stranger and ask him to leave your home immediately with the two-way audio function. Its application can also extend to wide areas like drawers, garage doors, blinds, etc. Just stick it anywhere two things connect and it is always safe even if you don’t keep watch on it.
