Once installed, the sensors can be effortlessly integrated with the YoLink Hub, which can support up to 100 LoRa sensors. The hub is compatible with Amazon Alexa, Google Assistant, and IFTTT, allowing you to control your smart home devices using voice commands or app integrations.

The Yosmart door sensors are designed to be versatile and adaptable to various environments. They can be used to monitor not only doors but also windows, cabinets, and other valuables. The sensors can detect not just open and close events, but also 1/4 open states, providing you with detailed information about the status of the secured area.

The sensors have a built-in rechargeable battery, which can last up to 2 years on a single charge. The battery can be easily recharged using the included USB cable. The sensors also come with a temperature sensor, allowing you to monitor the temperature of the secured area as well.
