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.
