I’ve been on a journey to automate my bathroom experience, and I’m thrilled to share my setup with you! 
After experimenting with various automation methods, I settled on a reliable system using timers and sensors. Here’s how it works:
Motion and Door Sensors: I use a motion sensor and a door/contact sensor to detect activity and presence. The motion sensor triggers the lights and fan, while the door sensor ensures the system knows when the room is occupied.
Timers for Precision: I implemented two timers—one for the light and one for the fan. The light turns off after a set period of inactivity, while the fan stays on slightly longer to ensure fresh air circulation.
Redundancy for Reliability: The system uses both motion detection and door status to start countdowns. This redundancy ensures that the lights and fan turn off even if one trigger fails.
This setup has been a game-changer for me. It’s energy-efficient and provides a seamless experience every time I use the bathroom. Plus, the ability to customize timers means I can adjust settings to fit my routine perfectly. 
If you’re looking to automate your bathroom or any space, I highly recommend exploring timer-based systems. They might just be the key to the smart home of your dreams!
