The Ecobee integration built into Hubitat Elevation allows you to add your existing Ecobee thermostat to Hubitat Elevation. With this integration, you can view and control your thermostat from both Hubitat and the Ecobee app. You can, of course, still also control the thermostat from the device itself.
For example, you can use your Ecobee thermostat with the built-in Thermostat Scheduler app on Hubitat to:
Automatically adjust your thermostat using time of day
Automatically adjust your thermostat using hub mode (day, night, away, etc.)
Create an “eco mode” that adjusts the actual setpoints a couple degrees (or whatever you configure) up or down from the regular schedule when activated
If you use Thermostat Scheduler on the hub, we recommend disabling any scheduling you may have already configured directly on Ecobee to avoid one overriding the other unexpectedly.
With Hubitat Elevation’s Ecobee integration, you can make use of events and conditions you may already be using on your hub to automate your thermostat in conjunction with other devices on your hub, and you can create advanced automations offered by Hubitat that the manufacturer app may not offer.
