First, determine whether you are using a Wi-Fi connected door lock or a Bluetooth/Zigbee connected one.
If you are using a Bluetooth or Zigbee door lock, please check the online status of the lock. If the lock is currently online, you can directly open the door remotely through the app. If the device appears online in the app but you are still unable to unlock remotely, try using a fingerprint or password on the lock itself to see if the app immediately receives the door opening record. This will help determine if the network is truly functioning properly.
If you are using a non-always-on Wi-Fi door lock (meaning you cannot directly remotely open the door through the app and the lock needs to be locally operated first), the app will display a call interface for remote door opening requests after someone initiates the request locally at the lock. The administrator user needs to respond to this request within a specified time frame (usually 60-90 seconds) to approve the door opening. Only after the approval, the door lock will be opened.
