🏠 Connect nudges with Home Assistant sensors

[adrianwedd]

Summary

Integrate nudges with Home Assistant sensors to create context-aware, environmentally responsive nudges based on real-world conditions and user presence.

Integration Opportunities

Presence Detection

• Motion sensors: Detect if user is in specific rooms for location-based nudges
• Occupancy sensors: Know when workspace is occupied for work-related nudges
• Door sensors: Detect arrivals/departures for routine transition nudges
• Bluetooth presence: Use phone/device presence for proximity-based nudging

Environmental Context

• Light sensors: Adjust nudge timing based on natural light levels
• Temperature/humidity: Include comfort reminders in nudges
• Air quality: Suggest breaks or window opening when air quality is poor
• Weather integration: Outdoor activity suggestions based on weather

Device State Awareness

• Computer activity: Detect prolonged computer use for break reminders
• TV/entertainment: Adjust nudges when user is relaxing
• Smart plugs: Know when work devices are active
• Sleep sensors: Respect sleep patterns for routine scheduling

Use Cases

Work Environment Nudges

• "Motion detected in your office after hours - remember to take breaks!"
• "Your workspace temperature is getting warm - time for a fresh air break?"
• "I notice you've been at your desk for 3 hours - the garden has great light right now!"

Health and Wellness

• "Air quality in your office is declining - how about a walk outside?"
• "It's been 2 hours since movement detected - time to get that body moving!"
• "Perfect weather for a walking meeting - take your next call outside!"

Routine and Transition Support

• "Welcome home! How was your day? Ready for your evening wind-down routine?"
• "Motion detected in kitchen - perfect time for that hydration reminder!"
• "Bedroom lights just turned on - shall we start the bedtime routine?"

Technical Implementation

Home Assistant Integration

• Home Assistant REST API integration
• WebSocket connection for real-time sensor updates
• Entity state monitoring and change detection
• Authentication and secure connection setup

Sensor Data Processing

• Sensor state filtering and relevance scoring
• Pattern detection from sensor data
• Context building from multiple sensor inputs
• Privacy-aware sensor data handling

Nudge Context Enhancement

• Sensor data integration into nudge decision making
• Environmental context in nudge personality selection
• Location-aware nudge routing to appropriate devices
• Sensor-triggered nudge scheduling

Configuration and Privacy

• User control over which sensors influence nudges
• Privacy settings for sensitive sensor data
• Sensor availability and fallback handling
• User-defined sensor-to-nudge rules

Sensor Categories

Essential Sensors

• Motion/occupancy sensors in key rooms
• Door/window sensors for transition detection
• Computer/device activity monitoring
• Presence detection (phone, wearables)

Enhanced Sensors

• Environmental sensors (temperature, humidity, air quality)
• Light sensors for circadian rhythm awareness
• Weather station data
• Sleep and activity trackers

Smart Device Integration

• Smart speakers/displays for nudge delivery
• Smart lighting for visual nudges
• Smart plugs for device state awareness
• Security system integration for presence

Privacy and Security

• Local processing of sensor data where possible
• Encrypted communication with Home Assistant
• User consent for different levels of sensor integration
• Audit logs for sensor data access and usage

Acceptance Criteria

• Home Assistant connection is established and maintained
• Key sensor states are monitored in real-time
• Environmental context enhances nudge decision making
• Location-based nudge routing works correctly
• Privacy controls allow user customization
• Sensor failures don't break nudge functionality
• Performance impact is minimal
• Integration works with common Home Assistant setups
