How do I set up a smart home hub and what wiring does it need?

A smart home hub itself needs minimal wiring — just a standard outlet and an ethernet connection to your router — but the devices it controls throughout your home are where the real electrical planning matters. The hub is the brain of your smart home system, and choosing the right one determines which devices, protocols, and automations you can use.

The most popular hub options for GTA homeowners are Samsung SmartThings ($100 to $130), Apple HomePod Mini ($130, for HomeKit-only setups), Amazon Echo with Zigbee ($60 to $180), and Hubitat Elevation ($150, local processing with no cloud dependency). Each supports different wireless protocols — Zigbee, Z-Wave, WiFi, Thread, and Matter. The newer Matter standard is designed to unify these protocols, but adoption is still early. For a robust setup, a hub that supports Zigbee and Z-Wave gives you the widest device compatibility.

Placement matters more than most homeowners realize. Your hub should be centrally located in your home, ideally on the main floor, connected to your router via ethernet cable (not WiFi) for reliability. If your router is in the basement — which is common in GTA homes where the internet service enters through the foundation — you may want to run a Cat6 ethernet cable from the basement to a central main-floor location for the hub. This cable run costs $150 to $300 if done by an electrician and ensures your smart devices communicate reliably across all floors.

The real electrical work comes with the devices your hub controls. Smart switches ($30 to $80 each) require a neutral wire at the switch box — a common issue in older Toronto homes as discussed earlier. Smart locks typically run on batteries and need no electrical work. Smart thermostats connect to your existing thermostat wiring, though some older GTA homes with only two thermostat wires may need a common wire (C-wire) added by an HVAC technician or electrician ($100 to $250). Motorized blinds and shades need either a nearby outlet or hardwired power, which an electrician can install for $200 to $400 per window location.

For homeowners building out a comprehensive smart home, plan a dedicated area for your networking and smart home equipment — a small shelf or cabinet in the basement utility room works well. This area should have a dedicated 20A circuit, a network switch for ethernet runs throughout the home, and adequate ventilation. Keeping all your networking gear in one organized location makes troubleshooting and upgrades much simpler down the road.

If your smart home plans include anything beyond plugging in a hub and screwing in smart bulbs — meaning smart switches, hardwired sensors, camera wiring, or dedicated circuits — a licensed electrician should be involved.
