I’ve recently undertaken a project to automate my bathroom ventilation system, and I’m thrilled with the results! Using a combination of a Shelly 2.5 relay and Home Assistant, I’ve managed to create a system that not only improves air quality but also enhances the overall comfort of my bathroom. Here’s how I did it and why you might want to consider something similar for your home.First, I connected my bathroom’s exhaust fan to the Shelly 2.5, which allows me to control the fan speed via Wi-Fi. The key to this setup is integrating it with Home Assistant, where I’ve set up automations based on humidity levels. When the humidity sensor detects a rise in moisture, the fan automatically adjusts its speed to ensure efficient ventilation without unnecessary noise. This is particularly useful during showers or baths when humidity levels spike.One of the most rewarding aspects of this project has been the reduction in noise. By programming the fan to run at a lower speed when humidity levels are moderate and only ramping up when needed, I’ve created a much quieter environment. This subtle improvement has made a significant difference in my daily routine, especially in the mornings when I want to start my day quietly.For anyone looking to replicate this setup, I’d recommend starting with a Shelly 2.5 or a similar Wi-Fi-enabled relay. The integration with Home Assistant is straightforward, and the community support is fantastic if you run into any issues. I also suggest investing in a reliable humidity sensor to ensure accurate readings, which are crucial for the system’s efficiency.In conclusion, automating my bathroom ventilation system has been a fantastic way to blend technology with practicality. It’s a simple yet effective solution that enhances comfort and efficiency. If you’re considering similar smart home projects, I highly recommend exploring this option.
