Phase 1 (Foundation): Start with a hub, a smart speaker, and a smart thermostat. This establishes your core ecosystem and begins energy savings.

Phase 2 (Security & Convenience): Add a smart lock, a few smart bulbs, and some door/window sensors.

Phase 3 (Expansion): Introduce smart cameras, more lighting, smart plugs, and potentially smart appliances or advanced sensors as your budget allows and your needs evolve.

Hidden Costs to Consider

• Professional Installation: If you're not comfortable with DIY, factor in the cost of hiring electricians or smart home installers, which can add $100-$500+ per project.
• Subscription Services: Some devices (especially security cameras) require optional monthly subscriptions for cloud storage, advanced features, or professional monitoring.
• Internet Service: Ensure your internet plan can handle the increased number of connected devices. You might need to upgrade your plan for better speed and reliability.
• Device Replacement: Like any electronics, smart home devices have a lifespan and may need to be replaced over time.

By carefully planning your budget and considering a phased approach, you can build a smart home that enhances your life without breaking the bank.
