Can I use Ecobee3 to control multiple disconnected zones

Yes, there is already an app for that. And it’s been used by many of my contributors.

The smartapp can do even more features based on the concept of zones:

  • Control of smart vents to create physical zones
  • Alternative cooling
  • Avg temp calculations based on any ST temp/motion sensors to make adjustment to your ecobee’s setpoints
  • More heat/cool thresholds based on an outdoor temp sensor.

Regards.
