Wi-Fi Door and Window Sensors, 4-Pack with Tuya App Alerts, No Hub Required

Wi-Fi Door and Window Sensors for Opening Notifications

Monitor selected doors and windows with this four-pack of wireless contact sensors. The sensors connect directly to a 2.4 GHz Wi-Fi network and work with the Tuya Smart or Smart Life app, without a separate hub. Opening notifications help you check activity at the entry points you choose to monitor.

The available option contains four sensors and explicitly excludes batteries. Before installation, check Wi-Fi coverage at each location and confirm the battery type from the product instructions. Notification delivery depends on network connectivity, app permissions and device settings; it is not an emergency-response guarantee.
