Made any change to your WiZ home (a new light, a new Scene, removed a lamp...) and you want this change to appear in Google Assistant?

Simply say "OK Google, sync devices"!

Otherwise, you can also hit the Refresh button on the Google Assitant integration page in the WiZ app:

iOS: Tap on the Settings tab, select Integrations, then Google Assistant.

Tap the "Refresh Devices" button to refresh and the changes will appear in Google Assistant after a few seconds.

Android: Open the side bar menu then the Home settings. Scroll down and select Integrations, then tap on Google Assistant. Tap the "Refresh Devices" button to refresh and the changes will appear in Google Assistant after a few seconds.
