Can more than one user command my faucet?
Yes, Google’s Voice Match functionality can be set up so that multiple users may control the Delta VoiceIQ® faucet. Google’s Voice Match allows for a more customizable experience and helps prevent unapproved users from giving commands to the faucet. If using Google’s Voice Match, your Google assistant will need to have additional approved users linked to your device.
