Cello is not a thermostat. It works seamlessly with your existing old or smart (Nest, Ecobee, and Honeywell) thermostat, in addition to a network of optional wireless sensors and inline dampers installed in specific areas of your home.
Cello makes old and smart thermostats smarter.
Airflow is controlled by installing patent-pending, battery-powered in line Cello Dampers in selected register boots based on your desired energy and operational modes. Cello’s inline dampers are easily installed below your existing register grille eliminating the need to change your register covers with plastic motorized dampers, allowing you to maintain your desired aesthetics.
The Cello Damper comes in several duct sizes, ranging from 3 to 6 inches.
Cello monitors the health of your furnace and AC or heat pump, allowing you to continuously receive and view critical performance data on the Cello App or any web browser.
