Challenge: Multiple Assistants in Same Home

• Solution: Position devices in different rooms
• Solution: Use distinctive wake words where configurable
• Solution: Consider using Matter-compatible devices

Challenge: Voice Purchasing Security

• Solution: Enable voice confirmation or PIN for purchases
• Solution: Disable voice purchasing entirely
• Solution: Create voice profiles to restrict purchasing

Best Practices for Voice Assistant Integration

Setup Best Practices

• Name devices with unique, pronounceable names
• Organize devices by rooms in assistant apps
• Create device groups for common control (e.g., “living room lights”)
• Position assistants centrally in rooms, away from noise sources
• Ensure consistent Wi-Fi coverage throughout home

Usage Best Practices

• Create routines/automations for common multi-step tasks
• Set default services for music, shopping, etc.
• Use voice training features to improve recognition
• Implement accessibility features for diverse users
• Regularly update device firmware and assistant apps

Privacy Best Practices

• Review and delete voice history regularly
• Enable notification sounds for when assistant is listening
• Use mute buttons when privacy is needed
• Configure voice purchasing restrictions
• Review third-party skill/action permissions

Multi-Assistant Best Practices

• Use each assistant for its strengths
• Standardize on Matter-compatible devices where possible
• Maintain separate shopping lists and calendars
• Position competing assistants in different rooms
• Use a hub system that works with multiple assistants
