Lutz Finsterle	5f22df3e0f	Refresh forecast up to 3× per day within daylight window ... forecast.solar updates estimates as the day progresses, so a single morning fetch can be stale by afternoon. New behaviour: - Re-fetch every 4h within 07:00–19:00 window (3 fetches/day) - Outside the window always serve the cached value - Free tier limit is 12 req/day — 3 fetches is well within budget - First startup outside window still fetches if cache is empty Config: forecast.fetch_interval, fetch_window_start, fetch_window_end Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-06 10:19:29 +02:00
