A:AnswerThank you for your question. You can control as many devices as you'd like using this sensor (50 devices per home location). If you intend to control them all at once they will need to be grouped within the Cync app and the sensor will need to be added to the room as well in the Cync app. Feel free to contact us at 1-844-302-2943 if you need assistance. -Cync Support
