FAQs

Harmony support for multiple Ecobee thermostats

Yes. Harmony will communicate with as many Ecobee Thermostats as you have in your Ecobee account. Each thermostat will appear as a different device on your Activity home screen, and each one may be controlled or associated with an Activity independent of the others.

Security information Harmony stores

Neither the Harmony Hub nor our Harmony servers store Ecobee username or password credentials. During authentication you are taken to a Ecobee webpage that allows you to enter your Ecobee credentials; however Harmony never sees this information. After signing in, Harmony will save a unique permission key that allows us to continue communicating with your Ecobee device.

Harmony does not track when you are home or away, nor do we track any temperature changes you make. Logitech Harmony respects your privacy. Read more about our privacy and security statement.
