Smart home tech promises to make life easier. In practice, it often means a different app for every device, automations that randomly stop working at 2am, and a Wi-Fi network that buckles under the load. After setting up dozens of these systems for Montreal homes, here's what actually works.
Start with the network — not the devices
The single most common mistake is buying smart devices before the Wi-Fi is ready for them. A budget router that handles four laptops fine will start struggling when you add 20 low-power IoT devices all trying to maintain a persistent connection.
Before buying anything, audit your network. You want:
- A router that supports separate 2.4 GHz and 5 GHz networks (most smart home devices prefer 2.4 GHz)
- No dead zones in the areas where you plan to put devices
- A stable, predictable internet connection — not one that drops nightly
Quick win
If you're on a rented ISP modem-router combo, that's usually the first thing to replace. ISP-provided hardware is almost never optimized for smart homes. A mid-range mesh system like the TP-Link Deco or ASUS ZenWiFi makes a significant difference.
Choose one ecosystem — and commit to it
The ecosystem problem is real. If half your lights are HomeKit, your thermostat is Google Home, and your locks are SmartThings, you're going to spend more time troubleshooting integrations than actually using the system.
The three main options in 2026:
- Apple HomeKit / Home app — best privacy, best integration if you're all-Apple, smaller device selection
- Google Home — wide device compatibility, strong voice integration, requires a Google account
- Home Assistant (self-hosted) — maximum control, works with everything, requires more setup time
If you're looking for something in between — good device support, local control, without the complexity of Home Assistant — I've been recommending Homey Pro for Montreal clients. It bridges Zigbee, Z-Wave, and Matter devices without requiring a cloud subscription.
A note on Matter
Matter is the new cross-platform standard that promises devices will work with any ecosystem. In practice, it works well for simple devices (bulbs, plugs) but more complex integrations are still catching up. Buy Matter-compatible devices when you can — it preserves your options.
The order of operations
If I'm setting up a smart home from scratch, here's the sequence I follow:
- Network audit and upgrade if needed
- Choose and install a hub (Homey Pro, Home Assistant, or native app ecosystem)
- Start with lighting — it's low-risk, high-impact, and easy to test automations
- Add sensors (door/window, motion, temperature) — these power the best automations
- Tackle locks and security last — get comfortable with the system before putting access control on it
Common mistake
Don't try to automate everything at once. Start with one room, get it working properly, then expand. The frustration usually comes from people who buy 40 devices, set everything up in a weekend, and then spend the next month dealing with conflicts they can't diagnose.
Automations that actually get used
The best automations are invisible. They just work, without you having to think about them. The ones I see used most in practice:
- Lights on when motion detected in specific rooms, off 5 minutes after motion stops
- Morning routine — gradual light warmup, thermostat adjustment, starting the coffee maker
- Away mode — triggered when everyone's phone leaves home, turns off lights, adjusts temperature, arms sensors
- Arrival mode — unlocks the door, turns on entry lights, disarms sensors when you return
The ones that sound good but tend to get turned off within a week: overly complex scene sequences, automations that require voice confirmation, anything that interrupts what you're doing.
When to call for help
Most smart home setup is genuinely DIY-able. But there are a few situations where it's worth getting a professional involved:
- Your Wi-Fi needs rethinking (wrong placement, wrong hardware, persistent dead zones)
- You want to integrate smart locks, alarm systems, or anything security-critical
- You've ended up with a mix of ecosystems and want to consolidate without starting over
- You want a Home Assistant setup but don't have the time to learn it
