# Sunlight Visualizer 0.3.1 — Code fixes.

Sunlight Visualizer 0.3.1 — Code fixes.

• Animation of power would fail during FPS limiting. (Thank you @rruki for telling me)
• Warning about thread safety in HA (Thank you @HACS-bank for telling me)

New full actual 3D scene in the works!
Will try to get it going as soon as possible:-)

Sunlight Visualizer 0.3.0 — Big Solar Intelligence Update

This is a big release focused on making Sunlight Visualizer more useful, more visual, and much easier to understand.
We also have a new Wiki here: Wiki!

4 Big Highlights

1. Smarter sun sensors
New Wall Sun Angle sensors help you understand not just if a wall is lit, but how low/deep the sunlight enters.

2. Optional Open-Meteo radiation
Add forecast-based radiation sensors for walls and roof, including direct radiation, total radiation, shading demand, and roof radiation percentage.

3. Better visual card
The card now has improved Energy HUD, surface % source selectors, EV car choices (Thank you @garylovesbeer for the suggestion 👍), WebGL fallback, and cleaner powerline/occlusion behavior.

4. More automation-ready
Use the new Open Meteo sensors for automations to make it work perfect for your installation and the current sun radiation.

What’s New

• Added optional Open-Meteo radiation support.
• Added Wall Sun Angle sensors for all walls.
• Added Wall Radiation Direct and Wall Radiation Total sensors.
• Added Wall Shading Demand and Wall Shading Status sensors.
• Added Roof Radiation and Roof Radiation Percentage sensors.
• Added Open-Meteo diagnostics and cache/retry handling.
• Added surface % source selectors for wall and roof labels.
• Added improved Energy HUD with optional CAR row.
• Added EV charger sensor and charger pulse.
• Added EV car selector: Mini SUV, Smart car, and SVG car.
• Added WebGL support detection with SVG fallback.
• Improved powerline, pole, car, tree, and sun visual layering.
• Improved HACS resource registration and cache-busting.
• Updated README with clearer visuals and setup guidance.

Fun Automation Ideas

• Close blinds when Wall Shading Demand gets high.
• Trigger awnings when a wall has strong direct sun and low sun angle.
• Pre-cool rooms before roof or wall heat load peaks.
• Compare Roof Radiation Percentage with solar production to spot underperformance.
• Show EV charging in the card with a live CAR value and charger pulse.

Notes

Open-Meteo radiation support is optional and disabled by default.
Existing default sunlight/alignment sensors continue to work without any external API.
