You can choose to have your Sensi thermostat on a programmed schedule or in geofencing mode (or no schedule). Only one option can be turned on at a time.
If you’re a busy person with no set schedule, the geofencing feature allows you to be more efficient with your heating and cooling energy usage without needing to remember to adjust your thermostat.
If you tend to have a predictable schedule from day to day and week to week, the scheduling feature may fit your lifestyle better.
