Amazon has announced a bunch of new Alexa devices lately. Thanks to smart add-ons like the THIRDREALITY Motion Sensor for Echo Flex, you can do more with them. The THIRDREALITY Motion Sensor lets you create routines that are triggered when motion is detected.
You can customize Alexa messages when motion is triggered. The sensor has a range of up to 20 feet. This smart sensor is expected to be released in November.
