I’ve recently set up an automation system for my bathroom exhaust fan, and I’m thrilled with how it’s working out! I wanted to share my journey and some tips for anyone looking to do something similar.
My setup involves a Sonoff smart switch connected to my exhaust fan and a Hue bulb in the bathroom. The goal was to ensure the fan runs long enough to clear out humidity, especially after a shower.
Here’s how I approached it:
-
Initial Setup: I started by linking the Sonoff to the Hue bulb. The idea was simple: when the light turns on, the fan should activate. But I quickly realized I needed a more refined solution.
-
Advanced Automation: I decided to implement a system where the fan runs for a set period after the light turns off. This ensures the bathroom stays dry even after I’ve left. I set it to run for 5 minutes post-shower, which has been perfect for my needs.
-
Handling Longer Showers: I also wanted to account for longer showers. If the light stays on for more than 3.5 minutes, the fan runs for an additional 10 minutes after the light turns off. This adjustment prevents any lingering moisture.
-
Challenges and Solutions: One thing I struggled with was the delay in turning off the fan. I realized I needed a way to reverse the timer logic. After some research, I found that using templates in Home Assistant was the key. It allowed me to create a more dynamic system that adapts to how long the light was on.
-
Final Thoughts: This setup has been a game-changer for my bathroom. It’s hands-off, energy-efficient, and ensures a mold-free environment. If you’re considering something similar, I highly recommend experimenting with templates and automations. They offer a lot of flexibility and can be tailored to your specific needs.
If anyone has questions or suggestions, feel free to drop a comment! I’d love to hear how others are tackling similar challenges.
