Review: Diseño y funcionalidad para alarma o apertura con notificación directa por wifi - Aquí tenemos un sistema de interruptor de apertura ya sea de puertas como de ventana que nos permite conocer en todo momento a través de nuestra aplicación o desde el sistema de Alexa si se encuentra esa puerta abierta o cerrada para una mayor seguridad tanto corta como ventana y a la vez también podemos activar con el sensor cualquier sistema inteligente emparejado que ya hayamos enlazado como rutina por ejemplo grupo de luces con temporizador. Este sistema se sobrealimenta de dos filas Triple A que viene incluida aunque yo recomiendo sustituirla por una de recargable ya que sale más económica pero se agradece que vengan en tu vida y su instalación es muy sencilla solamente con él en la fila y darle a emparejar automáticamente no los detecta el sistema Alexa y Google home
