Precision Astronomical Control
ASTmicro uses a high-precision real-time clock synchronized with the GPS location of the user’s smartphone, ensuring that lighting is switched according to the actual local sunrise and sunset times.
The controller supports up to four independently programmable switching periods, together with separate time corrections for summer and winter, allowing lighting schedules to be precisely adapted to local operating conditions.
Wireless Wi-Fi Configuration
ASTmicro is fully compatible with the free ASTmicro mobile application, providing complete configuration and diagnostics directly from a smartphone or tablet.
Communication is performed via a secure Wi-Fi connection using WPA/WPA2 encryption.
Using the mobile application, users can:
- Configure lighting schedules.
- Monitor the controller status.
- Perform service switching for 1, 10, or 30 minutes, or continuous operation.
- Review event history.
- Synchronize the controller time using the smartphone’s GPS location.
The service switching function significantly simplifies maintenance and servicing of lighting infrastructure.
