Many people have encountered this situation: they didn’t bring their keys when they went out, only to find out when they got home that they had to wait there stupidly for their family members to come back and open the door; if they live alone, I had to call the locksmith to open the door. Designers designed a multi-functional smart lock for this situation. When you go out, if you are not sure whether you have locked the door, you can know clearly by looking at your phone; if it is not locked, you can remotely control the door lock switch through the mobile phone app. In addition, it can be bound to your mobile phone. Every time you come home and approach the door, it will communicate with your mobile phone through Bluetooth to automatically unlock the door, so you don't have to worry about forgetting to bring the key. And when it is opened manually by the key, a message will be sent to your bound mobile phone to remind you to let you know whether the person who opened the lock is a thief. Also, if someone knocks on the door, it will send a message to notify you. Applications for Android and other mobile systems are still under development. This product is expected to be launched in March 2013, we will wait and see!
