First prerelease on the calendar-versioning scheme aligned with HA core. Same deliverable as the v1.8.3 beta cycle wrapped into a single coherent release; cut now to populate /beta on helios-lidar.org for live testing + screenshot work.
What ships
- HA Energy dashboard as the single source of truth for entity wiring (#184). PV / grid / battery / inverter slots resolve from
Settings → Dashboards → Energy; 11 per-card entity YAML keys retired. - Unified 5-day data store + radial sundial dashboard (#199, #210). One 480-bucket source of truth feeds the dial, the graph view, the timeline. The dashboard dive ships an annular radial sundial that absorbs the previous tiles + cumulative chart, plus a graph view whose Y-axis is locked to the install's peak power.
- Weather mode (#210). Top-right mode bar switches from
Layer / LiDAR / DometoLayer / LiDAR / Weather. Live RainViewer precipitation radar overlay, luminance-inverted to grayscale (light blue light rain → light grey, red storm → dark grey), refreshed every 5 minutes while the mode stays on. - Boot progress banner (#191). Phase-aware fill (energy-prefs, PV history, battery history, grid history, solar radiation, daily totals, weather forecast, buildings, LiDAR raster, LiDAR exposure) replaces the previous spinner.
- OpenMeteo rate-limit alert banner (#193). Surfaces under the loading banner on HTTP 429; HA
--warning-colorpalette, EN + FR copy. - Shading-map family retired (#210). Trainer + dome + editor panel gone; calibration ratio + LiDAR ray-march carry forecast accuracy on their own.
- i18n surface 11 → 63 locales, matching the HA frontend translation set.
Docs pass
- README rebuilt around the HA Energy refonte. Configuration table split into sections, retired keys called out in a "no longer configurable" block.
- ARCHITECTURE rewritten across the "What HELIOS does" + module description sections. New module entries:
unifiedStore.ts,dashboardRadial.ts,weatherMode.ts,grid.ts,loading-tracker.ts, etc. - CHANGELOG: v1.8.3 beta-by-beta inventory (38 entries) consolidated into one themed 2026.6.1 entry.
Site
helios-lidar.org will run this bundle at https://helios-lidar.org/beta automatically once the publish-prerelease workflow finishes. The stable demo at / and /coverage stays on the latest stable release until a non-prerelease tag is cut.
Known follow-ups
Six locales (tr, uk, ur, vi, zh-Hans, zh-Hant) still hold English placeholders for the new keys (the i18n batch agent didn't reach them before this cut); they fall back to EN at runtime. Will land in the next prerelease.
