WiFi Door Sensor for Smart Home Security

This WiFi door sensor detects when a door opens or closes and sends an alert to a connected app. It works with Alexa and Google Home so the status can be checked by voice or included in routines. The device connects to a home WiFi network without a separate hub. It is suited for renters or homeowners who want a simple entry monitor.

Ideal for Single-Door Monitoring Without a Hub

Buyers who need a sensor that reports door state to a voice assistant will find this a direct fit. It is not for installations that require a dedicated Zigbee or Z-Wave coordinator. It is not for setups that demand local-only operation without any cloud connection. It is not for monitoring more than one door unless multiple units are purchased.

Questions about this item

How can I confirm the sensor is reporting correctly after pairing it with Alexa?

Ask Alexa for the door status; if she replies with open or closed and the app shows the same state, the sensor is communicating properly.

What comes in the box and what must I provide separately?

The box includes the sensor body and its magnetic contact piece; you need a Wi-Fi network and a smartphone with the Tuya or Smart Life app to complete setup.
