Workflow Description

1. Sensor Detection

Temperature or humidity sensors detect a change in the indoor climate.

2. Evaluate Conditions

The system checks if the conditions warrant fan activation based on preset thresholds.

3. Activate Fan

If conditions are met, the system sends a command to the KNX fan to turn on.

4. Monitor Performance

The system continuously monitors the indoor climate and adjusts fan speed as necessary.

5. Deactivate Fan

Once optimal conditions are achieved, the fan is turned off to save energy.

Postconditions

The fans operate based on the automated settings, resulting in a comfortable indoor climate and optimized energy use.

Optional Enhancements

• Integrate with voice assistants for manual fan control.
• Add scheduling features for fan operation during specific times.
• Link with air quality sensors to activate fans when pollutants are detected.
