2026.9.2-a4

Pre-release. Fixes the rotation flicker on Android WebViews (#396, #370), keeps the energy diagram readable during auto-rotation (#397), and steadies the cost chip on coarse meters (#395). Supersedes 2026.9.2-a3.

No more flicker on Android tablets when the map rotates (#396, #370)

The "your real sky" weather grade was a CSS filter over the map, which forced the whole 3D scene to re-flatten every frame while rotating on Android WebViews (the HA app, kiosk browsers). The grade is now painted straight into the ground and buildings, so the map turns cleanly - and it drops a small per-frame cost on every device.

The energy diagram stays readable while the scene turns (#397)

With auto-rotation on, the sun path and the irradiance readout swept in front of the day's energy diagram, so you had to wait for the rotation to come round to read it. It now always draws on top of the sun path.

Cost chip steadies on coarse meters (#395)

A grid meter that reports every ~15 min leaves HA's cost sensor flat between reports, so the chip flashed between the real rate and 0.00/h while you were genuinely importing. It now reads the meter's cadence and holds the last report's rate between updates, while a genuinely stopped meter still falls to zero. Thanks to @Rag30.

How to test

Update to 2026.9.2-a4 (HACS pre-release) and hard-refresh / restart the kiosk. For #396 / #370, rotate the map on the affected tablet and confirm the flicker is gone. For #397, enable auto-rotation and confirm the day curve stays on top of the sun path.
