Amazon Echo, Echo Dot 4th Generation Models now get Motion Detection Features

For its newest Echo and Echo Dot devices, Amazon has included a new capability. The smart speakers will be able to detect occupancy in a house using ultrasonic and turn on/off linked devices like lights or your Fire TV.

The capability, which was initially revealed in September at Amazon's autumn hardware event, is now available for third-generation Echo and Echo Dot speakers. The Alexa app will allow users to enable or disable this capability. Users may now create occupancy routines that leverage the new capabilities to do activities like turning on lights upon entering a room and shutting them off when the space is empty.
