Can I open and close my vents manually with the app?

You will not be able open and close your vents through a manual setting in the app, but you can increase or decrease the temperature in your rooms through the app to get the vents to open and close. Since the communications protocol is optimized for battery life lasting 3-5 years, there may be a 60 - 90-second delay before the vents “wake up” and receive the radio signal from the control hub.
