![]() ![]() and 7 a.m.), otherwise you’ll keep triggering this action all day long. For this Routine, you need to also specify a time frame (such as between 6 a.m. If you like to get your news in the morning while brewing your coffee, Alexa can automatically deliver a salutation and give you a news brief or stream a podcast or a playlist as soon as it detects a person moving in the kitchen. If your window air conditioner is Alexa-compatible, then you can do the same thing without the smart plug. ![]() If you connect your fan or AC unit to an Alexa-compatible smart plug (like one of these), your Echo can turn it on automatically and keep it on when people are in the room. Turn on a fan or ACįans and air conditioners are great for cooling down a room on a hot day, but leaving them on when no one is in the room wastes a lot of energy. However we found it was fast enough and very reliable. Our Echos took about four seconds to turn the lights on, while our Hue sensor was almost immediate. Our tests found that Alexa’s ultrasonic sensor isn’t quite as fast as other infrared motion sensors we’ve tested, including the Philips Hue sensor. This can be especially helpful when going into dark basements or garages where the light switch may be out of the way, such as a cord hanging from a bulb in the middle of the room. If you have smart bulbs, or lights connected by a smart plug or switch integrated with Alexa, you can easily set up a Routine that turns the lights on when someone enters and stays in the room. What you can do with Echo motion sensing Automatically turn on lights All of these functions can be turned on or off in the Alexa app. In addition to ultrasonic motion detection, select Echos can be instructed to monitor for specific sounds, including the beeping of smoke or carbon monoxide detectors, barking dogs, breaking glass, snoring, or a baby crying (additional activity sound detection is available by activating Alexa Guard Plus for a fee). Also, it doesn’t create any light like some infrared sensors do, and it doesn’t detect through drywall, so it won’t accidentally react to sounds or motions from an adjacent room. One nice benefit of Echo’s ultrasonic ability is that it continues to work even while the same device is streaming audio, so you don’t need to pause your music. Separate infrared motion sensors such as these can be set up to do the same thing, but if you have a compatible Echo, you may not need the additional sensors. You can also adjust the sensor’s sensitivity and range in the Alexa app. Using Alexa Routines (Alexa-speak for a simple command program), also found in the Alexa app, you can trigger actions when the speaker detects the presence of someone in the room. Your speaker then uses its built-in microphone to monitor changes in how the waves bounce back to it, which happens when the waves encounter something moving, like you. When enabled in the Alexa app settings, the Echo continuously emits sound waves that are imperceptible to humans. Although some third-party Alexa-enabled speakers may include features such as better audio, weatherproof ratings, or rechargeable batteries, only Amazon Echo speakers include this additional capability.Įcho speakers use ultrasonic sound waves to detect motion, similarly to how a bat uses sonar to find insects. Ultrasonic sensing isn’t available on older Echos or any Echo Show display (they have camera-based motion sensing), nor is it on the new Echo Pop. If you have a 4th-gen Echo or Echo Dot or a 5th-gen Echo Dot, you’re all set. Which Echo smart speakers have ultrasonic sensing? It can act like a smart motion sensor and perform tasks such as turning on lights or air conditioning, as well as alerting you to intruders, without your having to buy extra sensors that take up space and burn through batteries. Once it hears that wake word from you, “Alexa, play ‘Funkytown,’” it springs to action.īut did you know that many Echo speakers have a hidden power you can put to use? With built-in ultrasonic detecting abilities, your Echo can do more than just respond to questions. If you own an Amazon Echo smart speaker, then you already know it’s listening, waiting to be called on like a Labrador retriever. ![]()
