Local and Remote Kitchen Gas Leak Alerts and Automations. In case of gas leakage, the Gas Detector will notify you even if you are away from home or will run the automations you have configured.

• Group Binding: Without any extra actions needed, one Gas Detector will trigger the other Aqara Gas Detectors to sound an alarm, even if the hub goes down.
• Zigbee 3.0 with Repeater Functionality: Enjoy the benefits of Zigbee 3.0, the fastest, and most energy-efficient smart home technology and increase your Zigbee network's stability. Aqara devices that sometimes could not reach the hub will reconnect to the Gas Detector automatically. 
• Rich Notifications: The detector will not only trigger all of your siren-equipped Aqara Hubs automatically via the Alert System, but also will be able to send configurable push notifications (including Critical Alerts) to your phone or any other device where the Aqara Home app is installed.
• Built-in up to 85 dB* Siren: The device has a built-in powerful siren that will allow you to hear it even if you are in another room, sleeping or listening to loud music. Also, the device has a colorful LED that will blink in case of an alarm.
• Smart Home Automations: The Gas Detector is a natural part of the Aqara Home app and its automations. You can configure the IF conditions as well as THEN actions, and you will be able to use more notification or disarming options. 
• Compatibility with HomeKit, Yandex** and more: Compatible with most popular smart home ecosystems. HomeKit, Yandex, IFTTT, and more are supported. Just connect it to the Aqara Hub and bind the account.
