If you’ve ever stared at a half-used space heater still running in an empty room, or realized your coffee maker turned on at 7 a.m. while you were on a weekend getaway, you’ve probably thought about ways to cut waste from your home energy use. As someone who’s spent the last five years working for a wifi controlled outlet supplier—testing designs, troubleshooting glitches, and answering hundreds of customer questions about our products—this is the question I get more than any other: Are these things actually energy efficient, or just another tech gadget that promises more than it delivers? Wifi Controlled Outlet
Let’s start with the basics, because there’s a lot of misinformation out there about how smart outlets work, and how they stack up against the standard, old-fashioned outlets most of us have used for decades. First, a quick breakdown: a wifi controlled outlet is a wall socket you can control from your phone, or set to run on a schedule, or even activate with voice commands like Siri or Alexa. It replaces a traditional outlet, but adds small electronic components: a wifi chip, a relay switch, and a tiny circuit board that handles the communication. The big selling point, at least for energy, is that it lets you turn devices on and off remotely, or automate their use so they only run when you need them.
The first thing I tell anyone asking about energy efficiency is this: the outlet itself uses almost no energy. I’ve done side-by-side tests in our lab, and our wifi controlled outlets draw around 0.5 watts on standby—less than a single LED nightlight, and only a tiny fraction of the standby power a common television or gaming console uses. The average home has 20 to 30 such “vampire” devices plugged in, drawing 5 to 10 watts each when they’re not in use. Our outlets use less than one watt to stay connected to the wifi, so over a year, that adds up to about 4.3 kWh per outlet—less than the energy it takes to charge a smartphone twice. For context, the average U.S. household uses about 900 kWh per month, so that’s a drop in the bucket. The real energy savings don’t come from the outlet; they come from how you use it to control the devices plugged into it.
Let’s get concrete here. I had a customer in Ohio last year who bought 12 of our outlets for his rental properties. His biggest waste was window AC units, which he’d forget to turn off when tenants left for winter, or forget to lower the temperature when no one was home. After six months, he sent me his energy bill: he cut his monthly electric cost for those three units by 38%. How? He set the AC to shut off automatically when the apartment’s thermostat (which he also connected to our outlet) reached 78 degrees during work hours, and turned on an hour before tenants got home. No more running cool air to an empty space. That’s the kind of savings people miss when they only look at the outlet’s own power use.
Another example: my own home. I used to leave my space heater running all night in my bedroom, even though I wake up at 6 a.m. and my partner works nights. With our outlet, I set it to turn off after I fall asleep at 11 p.m., and turn on 10 minutes before I wake up. I calculated that cuts my space heater’s energy use by about 40%—I still get warm when I need it, but I’m not wasting heat while I’m asleep or at work. I’ve also got outlets controlling my Christmas lights, which I used to leave up for two extra weeks after the holidays because I forgot. Now they turn off automatically on January 1, so that’s three extra weeks of no unnecessary power draw.
But wait, there’s a catch. A lot of people assume all wifi controlled outlets are equal when it comes to energy efficiency, and that’s not true. A low-quality outlet with a flaky wifi chip might struggle to stay connected, which means it might not turn off when you schedule it to, or it might cycle on and off unnecessarily to try to reconnect—wasting a tiny bit of power each time. That’s why we test every single unit before it leaves our warehouse: we check how much standby power it draws, how reliably it connects to wifi, and how precisely it follows schedules. A cheaper outlet from a big box store might save you a few dollars upfront, but if it’s inconsistent, you’ll end up wasting more energy than you save.
There’s also the myth that wifi controlled outlets are only good for small devices. Nope—we’ve had customers use them for everything from pool pumps to electric ovens. A customer in Arizona used our outlet to control his pool pump, which he used to run 12 hours a day to keep the water clean. With the outlet, he programmed it to run 4 hours in the morning and 4 hours in the evening, when electricity rates are lower, and only when the sun isn’t at its hottest (so less evaporation, too). He cut his pool-related energy bill by 29% in the first year. That’s not just convenience—that’s real, measurable efficiency, all because he could automate when his biggest energy user ran.
Of course, no tech is perfect, and there are scenarios where wifi controlled outlets don’t help with energy efficiency. If you set a schedule that’s actually more wasteful than not using one—like leaving your TV plugged in 24/7 and only turning it off when you remember, instead of using the outlet to cut standby power when you’re not home—you won’t save anything. It comes down to how intentional you are. The outlet is a tool, not a magic fix. If you use it to eliminate phantom load from devices you don’t use, or to run energy-hungry appliances only when you need them, it’s efficient. If you use it to control trivial devices that don’t draw much power in the first place, you won’t see a big difference.
I’ve also had customers come to me worried about connectivity issues leading to wasted energy. If your internet goes out, does the outlet stop working? That’s a common question, and it’s a good one. Our outlets store schedules locally, so even if your wifi is down, they’ll follow the times you programmed. You can also control them manually from the app, or even use them with a smart home hub that lets you control them via Bluetooth if your wifi is out. We designed that feature because we know how frustrating it is when tech relies on one single connection.
Now, let’s talk about long-term data, not just anecdotes. A 2022 study by the Department of Energy’s Office of Energy Efficiency and Renewable Energy found that smart home devices that automate appliance use can reduce residential energy use by 5 to 15% on average, with the biggest savings coming from heating, cooling, and pool pumps. Our own internal data from units sold over the last three years backs that up: customers who use our outlets for heating and cooling see an average 12% reduction in that category, which is way higher than the tiny energy used by the outlets themselves.
That said, it’s important to be realistic. A wifi controlled outlet isn’t going to cut your entire electric bill in half. But when you add up the savings from all the small, easy-to-implement changes—turning off space heaters when you’re not home, switching off decorative lights, cutting phantom load from chargers and routers—they add up. The average homeowner who installs five of our outlets and uses them strategically saves around $75 a year on their electric bill. Over the lifespan of an outlet (which is about 10 years, based on our testing), that’s $750 in savings. Compare that to the $20 to $30 cost of a basic wifi outlet, and it’s a no-brainer.
I also get asked about maintenance. Do these outlets wear out faster than traditional ones? So far, our data shows that they’re just as durable, as long as you’re using them within their rated wattage (we recommend not plugging a space heater or oven that’s over 15 amps into our standard outlets, though we do sell heavy-duty models for that). We’ve had units in customer homes for over six years with no issues, as long as they’re installed correctly by a licensed electrician. That’s another point: don’t try to install a high-wattage appliance into a regular outlet, even if it’s smart—always check the label.
What about the environmental angle, beyond just saving money? Less energy use means less demand from power plants, most of which still run on fossil fuels. If every household in the U.S. installed three smart outlets and used them to cut 10% of their home energy use, that would be the equivalent of taking 3 million cars off the road for a year, according to the EPA’s greenhouse gas calculator. That’s not a trivial number. For a lot of our customers, the energy savings are just a bonus—they also like the convenience of controlling their home from their phone, or not having to worry about turning off the porch light when they go on vacation. But the environmental impact is real, and it’s something we talk about a lot as a supplier.
So, to circle back to the original question: Are wifi controlled outlets energy efficient? The short answer is yes, when used properly. The outlets themselves use a negligible amount of energy, and the ability to automate device use and eliminate waste from forgotten appliances is proven to cut home energy use significantly. The key is choosing a reliable product, not cutting corners on cheap models that might glitch and waste energy, and being intentional about how you use them. If you’re just plugging in a lamp with a smart outlet, you won’t save much, but if you’re using them for space heaters, AC units, pool pumps, and other high-energy devices, the savings add up fast.
