The Flipper Zero is a versatile open-source hacking device that can be used for a wide range of tasks. However, it's important to note that manipulating or interfering with other people's property without their consent is generally not recommended or legal.
Instead of using the Flipper Zero to directly interfere with your neighbor's light, I would suggest addressing the issue in a more diplomatic and respectful manner. Consider talking to your neighbor about the problem and explaining how the light is affecting you. They might be willing to make adjustments or find a solution that works for both of you, such as redirecting the light or using curtains or blinds to block it.
Open communication and finding a compromise are usually the best approaches to resolving neighborly issues.
