How to Use This Calculator

Enter Number of Rooms, Avg Fixtures per Room, and Number of Outdoor Lights to capture your full lighting inventory.
Select your desired Automation Level (basic scheduling, motion sensing, full scene control) to determine system complexity.
Review Smart Bulbs Needed and Smart Switches Needed to decide between a bulb-first or switch-first approach.
Check Hubs Needed to understand whether you need a smart home hub or if your chosen ecosystem is hub-free.
Review Total Cost as your upfront hardware budget and compare to the annual savings projection.
Use Annual Energy Savings to calculate payback and prioritize which rooms to automate first for best ROI.

How the result changes with Number of Rooms

Number of Rooms: Total rooms to automate including hallways and closets if desired.
Avg Fixtures per Room: Average number of light fixtures or bulb sockets per room.
Outdoor Lights: Number of outdoor lights (porch, landscape, garage, etc.).
Automation Level: 0 = Basic (switches only), 1 = Moderate (mix of switches and bulbs), 2 = Full (every fixture smart).

Smart Bulbs Needed: Number of individual smart bulbs to purchase.
Smart Switches Needed: Number of smart switches to install at wall boxes.
Hubs Needed: Smart home hubs needed (1 hub supports ~50 Zigbee/Z-Wave devices).
Estimated Total Cost: Equipment cost: ~$12/bulb, ~$30/switch, ~$60/hub.
Annual Energy Savings: Estimated yearly savings from LED efficiency and smart scheduling at $0.12/kWh.
