Thermostat that pairs once and drops Wi-Fi at 11 PM. Cameras that 'forgot the cloud.' Pros who install, pair, test, and leave the system working — not just screwed to the wall.
What smart home install covers
DIY vs. hire — which makes sense for your job
When DIY works
If you're comfortable with a screwdriver, a WiFi network, and can follow an app wizard, most smart-home install is DIY-friendly: Ring battery doorbell, Lutron Caseta in-wall switch, Nest thermostat on existing HVAC wires. Where pros earn their fee: houses without a C-wire (Nest requires one, and some HVAC systems don't run one), hardwired doorbells with undersized transformers, or a smart-lock install that reveals a stripped door frame.
When to hire
A pro brings a C-wire tester, a transformer sizer, a set of standard smart-switch brands, and the patience to reset a flaky WiFi pairing. Most single-device installs: 30-60 minutes. Whole-home setups: 2-4 hours.
Permit, license, and safety
Smart home installation on existing wiring is handyman scope in California. Smart switches, smart thermostats, smart locks, smart plugs — all swap-in to existing electrical or mechanical setups. No permit required.
The line gets drawn at: running new wire for a wired doorbell where none existed, upgrading a transformer that doesn't support the new doorbell's amperage, or any work that adds load to the existing circuit. Those become licensed electrician (C-10) jobs if over $500 scope.
