The tunnel effect of the sun refers to the phenomenon where the sun appears to be setting or rising at the end of a long straight road or tunnel, creating the illusion that the road or tunnel is leading directly towards the sun. This effect occurs due to the perspective and the way light is refracted and reflected by the atmosphere, creating the appearance of a tunnel-like pathway towards the sun. It is a visually striking and often surreal sight that can be observed in certain atmospheric conditions, especially during sunrise or sunset. **

The radio control system also allows for integration with smart home systems, enabling users to control the roller shutter through their smartphones or other smart devices. **
