Weather, haze, and the indoor swap
Where the readings come from, the thresholds that swap the outdoor block for an indoor movement plan, and how Today, Places, and notifications show it.
Sources#
| Source | Used for | Notes |
|---|---|---|
| APIMS (Malaysian Department of Environment) | Air Pollutant Index, nearest station to the family's coordinates | Default provider. Falls back to Kuala Lumpur stations. |
| Open-Meteo | Temperature forecast and PM2.5 | Fallback provider anywhere in the world. PM2.5 is converted to the Malaysian index and labelled "estimated". |
No family data is sent. The family's city or coordinates select the station.
Thresholds#
| Condition | Effect |
|---|---|
| Air index above 100 | Outdoor block becomes an indoor movement plan |
| Temperature above 32 °C | Outdoor block becomes an indoor movement plan |
Either alone is enough.
Grades on the Today chip#
| Reading | Grade |
|---|---|
| Unknown | unknown |
| 50 or below | ok |
| Above 50 | moderate |
| Above 100 | amber |
Where it appears#
- Today: a banner such as "Haze API 161 (estimated) (>100) — indoor movement plan today." and the haze chip.
- Outside › Places: "Today {temp}° · haze API {api} ({label}) · outdoor before 9:30 / after 17:00", or "indoor movement plan today".
- Notifications: the parents' 06:30 morning haze check fires only when the reading warrants the swap.
Caching#
Readings are cached per family for 30 minutes. A simulated or past date uses its own cache, so a demo date never inherits this morning's haze.
