+### 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.
