Smart Switch Upgrades Without Rewiring in Fort Myers
We get asked about smart switches all the time — “Can I add them without rewiring my whole house?” The short answer? Yes. Most of the time, you can.
Here in Fort Myers, a lot of homes were built long before anyone thought about smart homes, Wi-Fi lighting, or Alexa turning the lights off for you. But that doesn’t mean you’re stuck with old switches forever.
We’ve upgraded plenty of homes — from 1960s bungalows near McGregor to newer builds in Gateway — and most didn’t need a single new wire run. You just have to know which smart switches work with the wiring you’ve got, and how to install them safely.
So, let’s talk about how to bring your home into the smart era without tearing into your walls.
If you’ve never used a smart switch before, here’s what you’re missing.
You can:
Turn lights on or off from your phone.
Set schedules or motion triggers.
Dim lights without rewiring for a dimmer.
Use voice control with Alexa, Google, or Siri.
Save energy by automating lights you always forget to turn off.
Once you get used to it, you won’t want to go back. We’ve seen homeowners turn entire lighting systems into smart setups without replacing a single fixture.
Smart switches also make older homes feel new again — like adding modern tech to classic architecture without losing the charm.
Most modern smart switches need something called a neutral wire. It’s what lets the switch stay powered even when the light’s off. Homes built after the late ’80s almost always have them. But older Fort Myers homes — especially those from the ’50s to ’70s — often don’t.
So what do you do if you don’t have a neutral? You’ve got a few options.
Use smart switches that work without a neutral.
Some brands (like Lutron Caséta, Aqara, and certain GE models) are designed specifically for older homes. They use a small trickle current or a companion hub to stay powered. No rewiring needed.
Use smart bulbs instead.
If your switches can’t be upgraded easily, you can replace the bulbs with smart ones and control them from your phone. It’s not as elegant as a switch solution, but it’s simple and effective.
Install a smart hub.
Some homes benefit from a hub that connects your Wi-Fi to older wiring setups. It acts as a middleman so you can still automate and control everything without running new cables.
We’ve installed all of these setups across Fort Myers — condos downtown, ranch homes out in San Carlos Park, even a few rental properties. The trick is choosing the right combination that fits your wiring and your lifestyle.
When someone calls us for a smart switch upgrade, we always start with a walkthrough. We check your switch boxes, see if neutrals are available, and identify any multi-switch circuits that might need special gear.
Then we talk through what you actually want. Some folks just want voice control in a few rooms. Others want the whole house on timers and motion sensors.
Once we’ve got that figured out, we match you to the right setup:
For older homes: We stick with neutral-free smart switches or hybrid systems that don’t need rewiring.
For newer homes: We’ll wire smart switches directly into your existing boxes and connect them to your Wi-Fi or hub.
For mixed systems: Sometimes it’s a combo — a few switches, a few smart bulbs, all tied together through an app or hub.
We’ve done enough of these around Fort Myers to know what works — and more importantly, what doesn’t.
Here’s something most people don’t think about: our Florida climate messes with electronics.
Humidity can corrode contacts inside switches, especially if you’re near the coast. Salt air doesn’t help either. That’s why we always use switches rated for high humidity or coastal conditions when installing near lanai doors, garages, or laundry rooms.
Wi-Fi coverage is another big one. Smart switches rely on a solid signal. If your router’s tucked away in a back office, half your switches might drop offline. We test coverage before we leave and recommend range extenders if needed. Nothing worse than a “smart” light that only listens half the time.
Most smart switch installs cost a lot less than people think. You’re not rewiring walls — just replacing existing switches with smarter versions.
A single smart switch usually runs between $100 and $250 installed, depending on the brand and setup. Full-home conversions can range from $1,000 to $2,500, depending on how many you want and whether a hub’s required.
Compared to a rewire, that’s peanuts. And you still get the benefits of automation, remote control, and energy savings.
We recently helped a homeowner near Whiskey Creek who wanted to control her porch and kitchen lights from her phone. Her home was built in 1974 — no neutral wires anywhere.
We installed a Lutron Caséta system, which doesn’t need neutrals. The main switch connected to a small bridge plugged into her router. Within an hour, she was turning lights on from her phone — and from the couch.
No drywall dust, no cutting, no rewiring. Just clean, functional smart lighting that fit the house as-is.
Sometimes we do recommend adding neutrals, but only if you’re already renovating or doing other electrical work. If your walls are open for a remodel, it’s easy to pull an extra neutral to the switch boxes. That opens up more smart switch options down the road.
But if your home’s finished and everything else is working fine? No need to tear into the walls. There are plenty of solid, reliable smart systems that work with what you’ve already got.
We’ve installed hundreds of smart systems in Fort Myers homes — from single switches to full-home setups that control lights, fans, and outdoor lighting.
We start with an inspection, figure out your wiring, and then walk you through your options. We don’t push fancy systems or subscriptions. We just help you get the features you actually want — things that make your home easier to live in.
Our team handles everything:
Wiring and installation
Wi-Fi and hub setup
App integration and testing
Instruction before we leave (no guessing what button does what)
We don’t leave until you’re confident using it.
