Please be aware of the following items.

The "IoT Console" provided by the platform is only available when the device is in Platform Mode. In Private Deployment Mode, the device will not connect to the platform. Therefore, after the device successfully enters Private Deployment Mode, the console will show the device as offline. Additionally, no device-specific operations (such as control, debugging, or log viewing) can be performed.
Due to the MQTT communication mechanism, there is a 30-60 second delay for the offline status to update.

Private deployment configurations are completed in the platform's [IoT Console]. The device needs to synchronize private deployment configuration information (such as gateway and Broker details). Therefore, after each configuration or modification of private deployment settings (gateway, message server), the device must be switched to Platform Mode to synchronize the configuration information. Only then will the configuration take effect on the device side.

Private deployment requires support from the device firmware. Before connecting the device to a private deployment scenario, ensure that the device firmware supports this feature. This can be verified using the firmware version number:
The firmware version number follows the format:
p[Product ID].[Compilation Date].v[Total Version Number].
All firmware versions with a compilation date (e.g., 20240611) on or after June 1, 2024, support private deployment.
If the compilation date is earlier than this, update the device to the latest firmware version.
The No Gateway Method is supported in firmware versions with a compilation date on or after December 31, 2024.
Devices are pre-installed with the latest firmware at the factory. Devices shipped after 2025 do not require a firmware update for private deployment.

If both valid gateway and Broker configurations are set for the device on the platform and have been synchronized to the device, the device will prioritize the Gateway Method.

When a firmware update is required for the device, the device must be switched to Platform Mode.
For specific methods, refer to the previous section "Device Working Mode Switching".
