No need for gateways or complex wiring, the door sensor connects to WiFi in a few steps. (Note: Only works with 2.4GHz WiFi, not works with 5GHz.)
Supports voice control by Alexa and Google home. After connecting Alexa and Google, you can know the status of the door and window by voice.
If the door is opened, it will send an alert to your phone and emits a sound and light alarm.
When the battery level is low, it will automatically remind you to change batteries, never worry about running out of battery.(The AAA batteries need to be purchased separately)
You can share your added devices with your family members, so they can also monitor the status of doors or windows.
