3.13.0-beta1

on GitHub

Beta pre-release. DWD wind shows the model step nearest to now, cached forecast tiles outlast a long refresh interval, zooming out stops multiplying tile requests, and thirteen fixes from a whole-project review. Drop-in upgrade from 3.12.0 — no config changes required. No breaking changes.

What's new

• Wind shows the model step nearest to now — the DWD wind overlays rounded the time down to the model's step, so ICON showed a slice up to an hour old and AICON (3-hourly, the default outside the US) one up to almost 3 hours old. They now pick the nearest step and refresh every half hour, so what's shown is within half a step of now.
• Cached forecast tiles are kept as long as the refresh interval — after a reload or a dashboard switch, stored DWD forecast tiles were reused only if their run was at most 30 minutes old, so with a long forecast_refresh_minutes a switch away and back discarded tiles the card was showing a moment before. The window is now the refresh interval plus 10 minutes, never less than 30. Suggested by @m42cel (#279).
• Zooming out no longer keeps the zoomed-in tile grid — the loop pinned its tile zoom to the highest level visited, so a four-level zoom-out drew 24 tiles per frame instead of 3 and a default loop could trip RainViewer's request limit. Tiles now follow the map's zoom.

Fixed

• A loop no longer freezes after a tab switch or a pan — a refresh that found nothing newer (about every other one) left the animation stopped, with the toolbar still showing playing.
• A card that loaded no frames retries on its own — a dashboard that started before its Wi-Fi was up, or during a source outage, showed an empty map until a pan or a reload. It now retries after 30 s, backing off to 5 minutes.
• A failed past frame no longer takes the forecast with it — the loop stops at the archive boundary as before, but DWD's forecast frames still load.
• Tile retries end with the tile — a retry armed after a failed tile request survived the tile leaving the map; with no network, a tablet's tiles kept retrying for the life of the page.
• Alert popups stay open across the 60-second refresh — the alerts layer redraws only when the alert set or its geometry changed.
• playback_speed applies from the first frame — without the viewer layer control the YAML value never took effect.
• An invalid dwd_time_override no longer leaves the map without radar when a wind overlay is on.
• Re-centre on mobile returns to the user's device tracker, as the initial view does, instead of the home location.
• Streamlines overlay with preload_while_hidden — every hide and show started another hourly refresh that outlived the card.
• Clearing a centre coordinate in the editor changed Home Assistant's own copy of the config in place.
• Very large alert polygons (a marine warning spanning many zones) could stop the alerts layer refreshing.
• Zone cache sweep — expired zone shapes are removed in one IndexedDB transaction instead of one each.
• A refresh interrupted by a teardown no longer arms one last update timer on the discarded player.

Internal

• The wildfire overlay computes each fire's extent once per fetch instead of on every Home Assistant state change (2.3 ms → 0.07 ms a tick with 90 fires).

Earlier

3.12.0 fixed US wind, added NOAA radar outside CONUS, cached DWD forecast tiles across reloads, and made map_style: Auto use Home Assistant's map tiles without a CARTO key.
