You can set up smart routines in the app, such as automatically turning on smart wall switches or lights when a door is opened, or turning off the air-conditioning when a window is opened. You can sync more smart devices as long as they are compatible with the Smart Life app. Please note that this sensor only supports 2.4Ghz Wifi and dual-band (2.4G and 5G) Wifi will require a separate 2.4G channel.

The TESSAN wifi garage sensor is compatible with Amazon Alexa and Google Assistant, allowing for hands-free voice control. You can simply give a voice command to check the open or close status, eliminating the need to physically check your phone. Your voice device can also work as a chime, siren, or alarm when the sensor is triggered, making your smart home life more convenient and efficient.

With all alarm record history accessible in the app, you can have peace of mind knowing that your home is secure. The smart window sensor features a built-in low consumption module, with 2*AAA Alkaline batteries providing 1-year monitoring. All door and window statuses will be displayed simultaneously in the app, and you can easily share the device with your family members so they can also check the status and receive notifications in real time.

Please note that the door sensor itself does not include a chime, but you can program it to work with smart voice devices via the Smart Life app. When the sensor is triggered to open or close, the voice devices will act as an alarm or bell within 10 seconds.
