After spending some time figuring out the correct setup, I thought it would be helpful to share my experience with configuring Modbus for Unelvent ventilation systems. This guide is based on the Modbus binding version 2 and has been tested with the Domeo 210 FL, though it should work with other versions as well.
Supported Models
Here’s a list of compatible models:
- Domeo 210 FL
- Domeo 210 + hygro sensor
- Domeo 210 constant airflow FL
- Flexeo 210 FL
- Flexeo 325 FL
- Ideo 300 constant airflow
- Ideo 450 constant pressure
Configuration Steps
- Install the Modbus Binding: Ensure the Modbus binding is installed in your system. No additional setup in the paperUI is required.
- Download Configuration Files: All necessary files (.items, .sitemap, .things, and transformations) are available on GitHub. The sitemap provided is basic and can be customized based on your specific ventilation model.
- Adapt to Your System: Modify the sitemap and other configurations to match your ventilation system’s specifications.
Benefits
This configuration allows for seamless integration of your ventilation system into your smart home setup, enabling real-time monitoring and control directly from your Home Assistant interface. It’s a great way to optimize airflow and maintain indoor air quality efficiently.
