In the Sync products page, you have 2 ways to push synchronisation.
Either to all devices in range, or to single ones.
To push to all in range, select the top main button, and the app will do its best to push the settings to all devices connected locally and in range. If some products are not powered on for example, those will not be able to receive the synchronisation.
Selecting a single product is also possible.
This can be used for more advanced use cases in which you would for example want to push different Wi-Fi credentials to different products.
You can identify the singular products by tapping on the magic wand icon to have them blink.
Please note: Wi-Fi credentials ( in the 'connectivity' step ) and the 'sync products' step are required before the handover of the project to the client. If these steps are not complete and a project handover is executed, the client will not have control over the WiZ devices.
