Changes on either device update both studies. Automatic activity previews temperature demand; connected devices should use reported heating and cooling flags. A connected host owns API calls, schedules, and override expiry. Room priority and sensor averaging are local T9 controls. Auto maps to heat_cool and allows equal targets in this preview.
