KaiSai TUYA-DS Door and Window Alarm: Wireless magnetic sensor for home security
This smart door and window sensor is perfect for renters or homeowners who want a simple, non-permanent way to monitor entry points. It’s ideal for keeping tabs on a frequently used back door or checking if a child’s window is secure at night.
While it’s a home security device, think of it as your first line of defense against everyday worries. The 100dB alarm sounds instantly if a door opens unexpectedly, and you’ll get a push notification on your phone before you even hear a noise. It works with Alexa and Google Assistant, so you can ask if everything is locked up without getting out of bed.
Installation is tool-free with the included adhesive tape, and the low power consumption means the batteries last for years with typical use. Link it to other Tuya Smart products to create custom scenes, like turning on lights when motion is detected, for a seamless smart home experience.
