away mode effectiveness

Smart Home and Away can lower HVAC use when the home is empty and restore comfort settings on return, though the reviews stop short of proving a specific savings result.

A reviewer says it automatically changed settings when leaving home and coming back.

Home/away or vacation behavior is supported, and the reviews describe useful away-temperature adjustments.

Away behavior is mixed: one reviewer likes the away setup, while another says occupancy-based away mode can misread absence when sensor coverage is limited.
