“YoLink” is a proprietary wireless technology provided by YoSmart. which is based on the Semtech’s LoRa wireless technology combined with the YoSmart smart home/building protocol, to provide the most advanced smart home/building devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily setup and is a very low cost but creates a reliable, robust, and more secure IoT network.

YoLink Siren Alarm is primarily used for YoLink device-assisted alerts based on YoLink Control settings or automation settings. It can also alarm itself through button control on the device or through the YoLink App. When an alarm occurs, the device emits a loud sound and a red light. If the alert is caused by a relative device, not on its own, you can tell from its history logs on YoLink APP which device triggers a warning. Support USB power or battery power. If there is a power outage, the device can keep working with 2 AA batteries (you need to purchase and install it yourself).

With YoLink APP and Hub, you can also control or monitor all YoLink smart home devices, such as plugs, switches, locks, gas/water Valves, sensors, and more. You can set scenes, automation, and YoLink Control between devices and devices, making your house smart. In all, you can build your own smart home system with YoLink.
