Does it cover all smart home protocols (Z-Wave, Zigbee, Matter)?

Equipment costs are entered per device regardless of protocol. The calculator shows total cost and annual energy savings estimates; protocol choice affects which hub you need.

How accurate are the energy savings estimates?

Savings use US DOE average electricity rates and published device efficiency data. Actual savings vary ±30% based on local rates, usage patterns, and occupancy hours.

Does it include subscription costs?

Yes — cloud subscription fees (Ring, Nest Aware, SimpliSafe) are factored into the 5-year cost of ownership alongside hardware.

About Home Automation Cost Calculator

Home Automation Cost Calculator preview - Real Estate & Home tool

Calculate home automation equipment and installation costs. Part of the DevTools Surf developer suite. Browse more tools in the Real Estate & Home collection.

Use Cases

Estimate the total upfront cost of outfitting a home with smart lighting, thermostats, and security.
Calculate ROI and payback period for smart HVAC controls based on current energy bills.
Compare DIY versus professionally installed home automation system costs.
Plan a phased smart home rollout by priority and estimated savings.

Tips

Calculate the payback period for smart thermostats separately — they typically pay back in 12-18 months via HVAC savings, faster than other smart home investments.
Include professional installation costs in your total — DIY smart switches save $50-100 per device but require electrical knowledge.
Factor in hub/controller cost once: a single hub (Hubitat, Home Assistant hardware) amortizes across all devices.

Fun Facts

The global smart home market reached $101 billion in 2023 and is projected to exceed $163 billion by 2028, driven largely by voice assistants and smart lighting adoption.
The Ecobee smart thermostat (2008) and Nest (2011) were the first consumer devices that made home automation mainstream outside of expensive custom-installed systems costing $10,000+.
Z-Wave protocol, used by many smart home devices, was invented in Denmark in 2001 by Zensys specifically for home automation — predating Zigbee (2004) and Matter (2022) by years.
