Can I control my lights with Alexa without a hub?

Yes, you can control lights with Alexa without a hub — as long as you choose smart bulbs or switches that connect directly over Wi-Fi rather than requiring a separate bridge device.

The most popular hub-free options are Wi-Fi smart bulbs like the TP-Link Kasa, Wyze, or Sengled Wi-Fi series. These bulbs screw into your existing fixtures, connect directly to your home's 2.4GHz Wi-Fi network, and link to Alexa through their respective apps. Setup typically takes under 10 minutes — no electrician needed for the bulbs themselves.

Smart switches are another excellent option, and in many ways the better long-term choice. Brands like TP-Link Kasa, Leviton Decora Smart, and Lutron Caseta (Caseta actually does use a small bridge, but others don't) offer Wi-Fi switches that replace your existing wall switch and work with any bulb in the fixture. This is especially useful if you have pot lights, chandeliers, or fixtures where swapping individual bulbs is impractical.

What to Know Before You Buy

The main thing to check is whether your existing switch location has a neutral wire. Most modern smart switches require one, and while most homes built after the 1980s have it, older Ottawa homes — especially those with knob and tube wiring or older panels — sometimes don't. If you're not sure, a quick look at your switch box will tell you (it's the white wire bundled separately from the others). If there's no neutral wire, look for switches specifically rated for "no neutral" installations, like certain Lutron or Leviton models.

When You'd Want a Hub

Zigbee-based bulbs (like original Philips Hue) traditionally required a hub, though Hue now offers some Bluetooth models that don't. Hubs do offer advantages — faster response times, more reliable connections, and the ability to run automations locally even if your internet goes down — but for most homeowners, hub-free Wi-Fi options work perfectly well.

A Note on Switch Replacement

Replacing a switch is one of the simpler electrical tasks, but always turn off the breaker first and confirm the power is off with a non-contact voltage tester before touching any wires. If you're uncomfortable working inside a switch box, or if your wiring looks unusual (aluminum wiring, older cloth-covered wires), it's worth having a licensed electrician do the swap. Electrical Ottawa can install smart switches as part of a broader lighting upgrade — and it's a good opportunity to check that your existing wiring is up to current ESA standards.
