Because we reuse the original OTA service and firmware version management system at present, iHost must be linked to the eWeLink account and connected to the eWeLink server to query and download the latest firmware version.

After linking the eWeLink account, the device will not synchronize any local device information and data to the eWeLink cloud except for querying and downloading the firmware. If you are worried about the data security of connecting to the cloud, you can download and update the firmware, then unlink the eWeLink account so that the device will disconnect from the server. Unlinking the eWeLink account will not affect any existing functions of the device.
