Make sure your Currant WiFi Smart Outlet is set up and your individual devices are named.
Open the Google Home app and tap the "Add" quick action on the Home screen.
Tap "Set up device".
Tap "Have something already set up?"
On the Add Devices screen, scroll down or search for "Currant" and tap on the Currant logo or name.
You'll then have two options: Quick Setup or Login. Choose "Quick Setup" if you are in close proximity to your outlets and can press the buttons. Your phone or tablet needs to be on the same WiFi network as your Currant Smart Outlet. Choose "Login" if you are not able to press the buttons on the outlet. You'll need to set a password on your Currant account to use this option.
Tap "Grant Access".
Choose the devices that you'd like to connect to Google Home.
Choose the name of the home and rooms where the devices are located.
You should now see your Currant Devices on the Home screen, and can control them with your voice. Try saying “Ok Google, turn off <Air Filter>.”
