🧠 Enhanced Nest Integration for ADHD Executive Function Support

[adrianwedd]

Overview

Expand the current Nest device integration to provide comprehensive ADHD executive function support through voice-first interventions, contextual awareness, and multi-device orchestration.

Current State

• ✅ 3 Nest devices connected (Hub Max, Mini, Home Mini)
• ✅ Basic broadcast nudges working
• ✅ Music playing on Chromecast Audio
• ✅ Cognitive loop with safety monitoring

Proposed Features

1. Time-Based Reminder System

Implementation: src/mcp_server/adhd_reminders.py

• Medication reminders with acknowledgment tracking
• Hydration prompts every 90 minutes
• Break reminders based on activity duration
• Meal reminders with nutritional suggestions
• Sleep hygiene prompts in evening

2. Contextual Awareness Integration

Implementation: src/mcp_server/context_engine.py

• Google Calendar integration for meeting prep
• Smart home sensor data (motion, light, temperature)
• Activity detection from computer usage patterns
• Weather-based mood adjustments
• Social context awareness (alone vs. with others)

3. Multi-Device Orchestration

Implementation: src/mcp_server/device_orchestrator.py

• Device-specific routing (visual to Hub Max, audio to Minis)
• Follow-me audio (music moves between rooms)
• Synchronized multi-room announcements
• Priority-based device selection
• Fallback chains for unavailable devices

4. ADHD-Specific Voice Interventions

Implementation: src/mcp_server/adhd_interventions.py

• Body doubling sessions ("I'm here working with you")
• Pomodoro timer with verbal countdowns
• Hyperfocus interruption with gentle transitions
• Task initiation prompts for paralysis moments
• Positive reinforcement for completed tasks
• Executive function coaching scripts

5. Smart Automation Sequences

Implementation: src/mcp_server/automation_sequences.py

• Morning routine scaffolding (gradual stimulation increase)
• Focus mode activation (dims lights, starts music, blocks distractions)
• Transition assistance between tasks
• Evening wind-down sequence
• Crisis intervention protocols

6. Enhanced Nudge System

Implementation: Update src/mcp_server/nest_nudges.py

• Urgency-based volume adjustment
• Personality modes (gentle, firm, playful)
• Acknowledgment detection via voice response
• Escalation chains for ignored nudges
• Contextual message adaptation

Technical Architecture

# Core components structure
mcp_server/
├── adhd_reminders.py      # Time-based intervention scheduler
├── context_engine.py       # Environmental & calendar awareness
├── device_orchestrator.py  # Multi-device coordination
├── adhd_interventions.py   # ADHD-specific voice scripts
├── automation_sequences.py # Complex behavioral chains
└── nest_nudges.py         # Enhanced with new capabilities

Implementation Plan

Phase 1: Foundation (Week 1)

1. Create reminder scheduler with Redis persistence
2. Add Google Calendar API integration
3. Implement device routing logic

Phase 2: Core Features (Week 2)

4. Build intervention library with templates
5. Create automation sequence engine
6. Add acknowledgment detection

Phase 3: Intelligence (Week 3)

7. Implement pattern learning from user responses
8. Add contextual message generation
9. Create adaptive timing algorithms

Phase 4: Polish (Week 4)

10. Add configuration UI in dashboard
11. Implement analytics and insights
12. Create onboarding flow

Success Metrics

• Medication adherence improvement
• Task completion rates
• User-reported focus quality
• Reduced anxiety around transitions
• Improved sleep consistency

Dependencies

• Google Calendar API credentials
• Home Assistant integration (optional)
• Redis for state persistence
• LLM for contextual message generation

Privacy Considerations

• All processing happens locally
• No personal data leaves the network
• User can disable features individually
• Clear data retention policies

Related Issues

• Add user authentication and session management #1 Initial Nest integration
• Research and plan second MCP domain (MCP-Therapy or MCP-Learn) #2 Music system implementation
• ⚡ Reduce LLM cold start time #3 Cognitive loop architecture

• ✅ Multiple personality modes (gentle, motivational, urgent)
• ✅ Contextual message adaptation based on situation
• ✅ Smart device routing (prioritizes Nest Hub Max for visual)
• ✅ TTS integration with external fallback

2. Time-Based Reminder System (MOSTLY DONE)

• ✅ ADHD reminder system active - src/mcp_server/adhd_reminders.py
• ✅ 10 reminders loaded including medication, breaks, hydration
• ✅ Pomodoro break reminders (25min work cycles)
• ✅ Bedtime nagging system with escalation
• ✅ Scheduler running and triggering reminders

3. Multi-Device Orchestration (DONE)

• ✅ 3 Nest devices connected (Mini, Hub Max, Living Room)
