Hey everyone! 
I’ve been diving into my latest smart home project, and I wanted to share my experience with integrating the Netatmo CO2 sensor to automate my bathroom ventilation. It’s been a bit of a learning curve, but I’m excited to see how it’s coming together!
So, here’s the setup: I’ve paired the Netatmo CO2 sensor with a Ruck exhaust fan and a 3-position switch. The goal is to have the fan automatically turn on when CO2 levels exceed a certain threshold and turn off once they drop below that level. I’ve also integrated this with Homey, using a moisture sensor as an additional trigger for bathroom ventilation.
I’ve set up two automation rules in Home Assistant:
- CO2 Level Trigger: The fan turns on when CO2 levels exceed 550 ppm and turns off when they drop below 500 ppm. I added a 10-minute delay to prevent frequent switching.
- Manual Override: I’ve also configured the 3-position switch so that it can override the automatic settings if needed.
Here’s where I’m hitting a snag: the sensor isn’t triggering the fan as consistently as I’d like, especially during peak usage times. I’ve tried adjusting the thresholds and delay settings, but the results are still inconsistent. Has anyone else encountered this issue? I’d love to hear how you’ve resolved it!
On a positive note, I’ve found the integration process surprisingly smooth, and the ability to customize the automation rules has been a real plus. It’s been a great way to ensure proper ventilation without manual intervention.
If anyone has tips or troubleshooting steps, I’d be grateful! Let’s keep the conversation going!
