Activate Devices in AP Without Internet

Without a direct connection to the internet, a Wi-Fi device can be activated with the mobile app acting as a proxy. After the mobile app completes the activation in the cloud, it connects to the access point (AP) of the target device and activates it.

Feature description

• Activate a device without internet: This is mostly used for IP cameras (IPC).

  1. The user scans the QR code on the device using the mobile app.
  2. The mobile app gets the device information and acts as a proxy to activate the device in the cloud.
  3. The mobile app connects to the AP from the target device to create a LAN.
  4. The mobile app sends the data point (DP) description received from the cloud to the target device for activation.
  5. Then, the mobile app can control and communicate with the device over the LAN.

• Perform OTA updates without internet:

  1. The mobile app downloads the update and then connects to the AP of the device.
  2. The mobile app sends updates to the activated device via a proxy, allowing it to install updates without internet access.

How to

Devices that can be activated without internet must have an AP name in the format of SmartLife-xxxx. xxxx is the last four digits of the device’s UUID. Make sure you set the AP correctly.

Activation without internet does not apply to all product categories. Check if the mobile app and panel support the use of this feature for your product.
