Many households and car owners face the common problem of accidentally leaving lights on when leaving their homes or vehicles. This wastes both electricity and money, while also causing unnecessary stress for forgetful individuals. A simple yet practical solution could help address this issue while contributing to energy conservation.

A Smart Lighting Reminder System

One approach would be to create a mobile app that connects with existing smart home or car lighting systems. When the app detects that the user has left their home or parked car (using GPS or geofencing technology), it would automatically check if any lights are still on and send a notification. The user could then remotely turn off the lights or choose to leave them on if needed.

For homes, this system could integrate with popular smart lighting brands like Philips Hue or LIFX. For vehicles, it might connect through the car's built-in system in newer models or use an OBD-II adapter for older cars. The key value lies in the proactive alert system that prevents energy waste without requiring constant manual checks.

Potential Benefits and Applications

This concept could particularly benefit:

• People who frequently forget to turn off lights
• Environmentally-conscious households
• Car owners concerned about battery drainage
• Smart home users wanting to maximize energy efficiency

A simple starting point could be developing a basic version that works with the most common smart home systems before expanding to include car integration and more advanced features. The system could potentially partner with smart device manufacturers to offer bundled services or create additional value for existing products.
