Solar Tracker Demo
Explore a simulated version of the ESP32 solar tracker interface. Change the time, requested angle, wind speed, and operating mode to see how the controller would respond.
SIMULATION ONLY
No hardware, motors, Home Assistant entities, or real trackers are connected.

What this demonstrates
Real concepts, safe simulation
The public demo mirrors the kinds of decisions the real controller makes without exposing device credentials or sending commands to a tracker.
Automatic tracking
Auto Sun uses a simplified solar-position model and calculates a south-only one-axis target.
Wind parking
At 40 mph or above, the demo overrides the selected mode and requests a flat position.
Closed-loop behavior
The simulated panel moves toward the requested angle and reports direction, error, and status as it moves.
