+### Garadget automations
+- Logic lives in [garadget.yaml](garadget.yaml): auto-open on arrival, entry helper prompt (unlock front door or open garage), auto-unlock for Paige/Justin, wind checks, nightly open-door reminders, and camera pop-ups.
+- MQTT-based covers for large/small doors; notifications and speech wired to the house notify/speech engines.

 ### Nest climate control
 - Logic lives in [climate.yaml](climate.yaml) and centralizes downstairs/upstairs Nest schedules, grid-aware guardrails, humidity pulses, and presence/weather-based targets.
 - Shared script keeps targets consistent: away → eco, home + >92°F → 78°F, home default → 80°F. Grid-down conditions pause non-essential cool-downs.
