This wireless smart siren is part of the ever-growing SmartLife™ series that makes it easy for you to create a smart home, with nothing but your Wi-Fi router and connected devices. The siren with flashing LEDs can be used as a doorbell or as a warning signal if a motion detector detects that something is moving. It has eight different sounds that can be triggered at certain times of the day, after a certain time (timer function), if a sensor has been triggered, or many other possible scenarios. It can be controlled via smartphone, tablet or with voice (via Amazon Alexa or Google Home). The loudness of more than 85 dB can be configured loud enough to be heard over the buzz of a room full of people.
