You will need at least one Puck to act as a gateway between your ecobee system and our Smart Vents.
For any room where you would like to install our Smart Vents, you will either need a Flair Puck or an ecobee Remote Sensor. If you would like to only use ecobee remote sensors, you will just need a single Puck in Gateway mode to act as a bridge between our Smart Vents and your ecobee.
