Air Purifier Auto Mode

S.C.O.R.E. → Convenience → Device Control

Overview

Air purifiers are essential for maintaining indoor air quality, but manual adjustments can be tedious. The auto mode capability allows the air purifier to automatically adjust its settings based on real-time air quality data, ensuring optimal air conditions without user intervention.

Benefits

• Ensures consistent air quality by automatically responding to changes in pollution levels.
• Reduces user effort by eliminating the need for manual adjustments.
• Promotes a healthier living environment, especially for individuals with respiratory issues.

Intent

The purpose of the air purifier auto mode capability is to continuously monitor air quality and adjust the purifier’s operation accordingly. This capability aims to maintain a predefined target air quality level, enhancing comfort and health for all occupants in the home.

Preconditions

• A compatible air purifier that supports auto mode operation.
• Integration with a home capability platform like Home Assistant.
• Air quality sensors installed to monitor indoor conditions.
• Home Assistant installed and configured.
• Integration available and authenticated: Zigbee2MQTT.
• Device installed and reachable: Gas Sensors.

Actors

• Homeowner managing air quality
• Family members affected by air quality
• Guests sensitive to allergens or pollutants

Trigger

The capability is triggered by real-time readings from air quality sensors indicating a drop in air quality below a predetermined threshold.

Workflow Description

1. Monitor Air Quality

The air quality sensors continuously monitor indoor air conditions and send data to the home capability system.

2. Evaluate Air Quality

The system evaluates the sensor data against the predefined target air quality levels.

3. Activate Purifier

If the air quality is found to be below the target, the system activates the air purifier.

4. Adjust Settings

The purifier adjusts its fan speed and mode (e.g., high, medium, low) based on the severity of the air quality issue.

5. Continuous Monitoring

The system continues to monitor air quality and will deactivate the purifier once optimal conditions are restored.

Postconditions

The air purifier operates in auto mode, maintaining the desired air quality level and automatically adjusting as conditions change.

Optional Enhancements

• Integrate with a smart thermostat to optimize energy consumption.
• Send notifications to the homeowner when air quality issues are detected.
• Log air quality data for long-term analysis and patterns.
