How to Enable Motion Detection on Amazon Alexa

You can enable Alexa motion detection to detect humans like any other motion detection device. The beauty of this feature is that this is a built-in feature with Alexa. You don’t need additional sensors or devices to get this feature to work for you.

Let’s look into this and see how to turn on Amazon Alexa’s Motion detector on your Alexa Device.

How to Enable Motion Detection on Alexa Devices

This feature is important for detecting and running the Alexa Occuappny Routines that can automate your Alexa routines, such as your AC control or controlling the lighter when you leave home.

Meanwhile, we notice a cool-off period for this motion detection on Alexa devices. This cool-off typically comes in 5-7 minutes. So you can expect a delay to work again if you set any routine with this motion detection.

How to Turn Off Motion Detection Temporary

Well, you can turn off this Motion detector right from the device settings. However, there is a quick solution for disabling motion detection. You can use the mute button on Alexa to disable motion detection temporarily. Well, like you mute your Alexa for the voice.

How Does Motion Detection Work

Amazon Echo devices emit ultrasound to determine the occupancy of the rooms. The internal microphones detect back these ultrasounds and analyze the presence of humans in the room. Since this is an ultrasound, we (humans) can’t hear this sound anyway. According to Amazon;

“Occupancy Routines, and some Alexa features, rely on motion detection to determine whether a room is occupied. When you turn on an Occupancy Routine or feature, some Echo devices emit ultrasound and use the device microphones to detect motion near the device. Alexa interprets such motion to mean that someone might be in the room.”

Does Motion Detection Work for All Motion?

As per amazon, the detector will work all the motions like waving hands or similar activities. This detector is designed to detect the parens or absence of human beings in a room. Amazon is giving an idea of the motion detection sensitivity here,

“Motion detection is designed to detect major motions, such as walking around the room. It might not detect minor motions, such as waving your hand or sitting still and reading. A routine also can start when no occupancy is detected, for example, by turning off lights when the room is empty.”

This feature was introduced a few years ago, and you get this feature on the latest Amazon devices; you need at least an Echo (4th Gen. or newer) or an Echo Dot (4th Gen. or newer) device to get these features. By default, this feature will be turned off on your Alexa devices; following the above steps, and you have to enable this. Here are a few Alexa devices that can work as motion detection.

As far as we know, this motion detection feature is available only in certain countries, including the US and UK. We hope this feature will roll out to other locations in the future.
