- Cost-benefit of comprehensive systems over piecemeal approach
- How technology reduces support worker reliance during symptom changes
Cognitive Disabilities
For clients with intellectual disability, acquired brain injury, or dementia:
Key Barriers
Memory and routine
- Difficulty remembering daily tasks
- Challenges with multi-step processes
- Need for structure and predictability
Safety
- Forgetting to lock doors or turn off appliances
- Difficulty recognising risks or hazards

Matching Technology to Severity
Mild Functional Limitations
Focus: Specific task support without comprehensive integration
Solutions:
- Single-purpose devices (video doorbell, smart lock)
- Basic voice control for common tasks
- Cost: $500-$2,000
Documentation: Focus on specific barrier addressed
Moderate Functional Limitations
Focus: Multiple integrated systems
Solutions:
- Voice-controlled lighting, temperature, security
- Basic integration between systems
- Cost: $2,000-$8,000
Documentation: Emphasise support hour reduction and safety improvements
Severe Functional Limitations
Focus: Comprehensive environmental control
Solutions:
- Full ECU with multiple access methods
- Integration of all home systems
- Custom automation for daily routines
- Cost: $8,000-$25,000
Documentation: Comprehensive cost-benefit analysis showing long-term support reduction
Common Pitfalls in Technology Matching
Recommending Based on Diagnosis, Not Function
Avoid: "Client has multiple sclerosis, recommend smart home system"
Use instead: "Client has reduced grip strength preventing key use, and fatigue limiting ability to reach switches. Smart lock and voice control address these specific barriers."
Over-Complicating Solutions
Avoid: Recommending comprehensive systems when single-purpose technology addresses the documented need
Use instead: Start with essential technology addressing primary barriers. Plan for expansion in future plans if needed.
Not Considering Symptom Fluctuation
Avoid: Fixed solutions that don't adapt to changing needs
Use instead: Flexible systems that can be adjusted as symptoms or needs change
Ignoring Client Preferences
Avoid: Technology solutions the client won't use
Use instead: Involve client in selection, trial preferred options, document preferences

Getting Started with Assessment
When matching smart home technology to disability type:
- Document functional barriers — What specifically can't the client do?
- Identify technology options — What addresses each barrier?
- Consider cost-effectiveness — Which solutions have highest ROI?
- Plan for flexibility — Can the solution adapt to changing needs?
- Involve the client — Preferences and usability matter for adoption
