Smart Plugs for Seniors: Safe Uses and the One Never To Do

The cheapest smart-home device that matters

One in four adults 65 and older falls each year, and falls are the leading cause of injury and injury death in that age group.⁶ A lot of the smart-home advice for older adults is about expensive things: cameras, hubs, sensors. The device that does the most for the least money is the humble smart plug, because so many falls start with walking through a dark room to reach a lamp.

A smart plug goes between the wall and an ordinary lamp or appliance. You set it up once in a phone app, and after that the lamp can be turned on by voice through an Amazon Echo or Google Nest, from a family member’s phone across the country, or on a schedule. A common model, the TP-Link Kasa EP10, works with “Alexa, Google Assistant, and Samsung SmartThings” and supports a “schedule and timer” to turn devices on and off at set times.⁵

The four jobs worth doing

1. A bedside lamp on by voice

The moment of highest risk is getting out of bed in the dark. With the bedside lamp on a smart plug, “Alexa, turn on the bedroom lamp” lights the room before feet hit the floor. The federal long-term care program’s guide describes a bedtime routine that turns off lamps and switches on night lights, which “can assist with safety and reduce fall risk,” and notes it can be started from bed.³ Pair it with the night-route advice in our lighting guide.

2. Lights on at dusk, every day

A schedule set to turn on the hallway and living room lamps at sunset means nobody comes home to, or wakes up in, a dark house. This is the set-and-forget job that helps most for someone who will never talk to a speaker. If there is no Wi-Fi in the home, a plain outlet timer does the same thing for a few dollars.

3. The morning routine and a quiet check-in

A morning routine can turn on lamps and the coffee maker together. The long-term care program’s example is exactly this: smart plugs that “turn on lamps and the coffee maker” when the person says “Alexa, good morning,” which is “helpful, especially during the winter months when the house may be darker than usual when they wake up.”³ AARP describes the same setup, a coffee maker on “an inexpensive smart plug” that “begins to brew” when a routine starts the day.⁴

The side benefit for family is that the plug’s app shows when the coffee maker came on. A glance at a phone at 8 a.m. says the routine happened, which many parents accept far more easily than a camera. Agree on it together, and treat it as reassurance, not a safety system.

4. Lights on a schedule while away

For a hospital stay, a winter away, or a weekend with family, a few lamps on varied schedules make the house look occupied. Our snowbird checklist and home security guide both recommend it.

The one never to do: space heaters

The numbers explain why. Space heaters were involved in about 45 percent of home heating fires but “nine out of ten deaths (88 percent),” according to the National Fire Protection Association.¹ Portable heaters were only 3 percent of home heating fires but 41 percent of the fatal ones, the U.S. Fire Administration reports.² An electric heater draws around 1,500 watts for hours, which runs a plug rated for 1,800 watts close to its limit all evening. Turn heaters on and off by hand, in the room. The same goes for anything else that heats for long periods. Our winterizing guide covers heater safety in full.

What a smart plug can handle

A typical plug is rated “15A” and “1800W (General Use, Resistive Load)” on a 120-volt outlet; that is the Kasa EP10’s published spec.⁵ AARP’s shorthand is that “a 15-amp smart plug can turn off a light or a coffee pot.”⁴

• Good fits: lamps, radios, fans, a coffee maker, holiday lights, a dehumidifier on a schedule.
• Bad fits: space heaters, electric blankets left on overnight, irons, anything that heats for hours.
• Impossible: the stove. AARP notes that “the electricity required for a range means a bigger, 50-amp plug with no smart versions available.”⁴ For a forgotten burner, use a stove shut-off device.

Setting it up for someone else

AARP is blunt about the hard part: “Buyers’ biggest pain point is setting everything up.”⁴ So do the setup yourself, in person, and leave a home that works without anyone opening an app.

• Wi-Fi band. Many plugs connect to “2.4GHz Wi-Fi only.”⁵ If setup fails, that is usually why.
• Plain names. Name each plug for what it controls, “Bedroom Lamp,” so the voice command is obvious.
• Test twice by voice, with the person speaking, before you leave.
• Show the button. Every plug has a manual switch, so the lamp still works when the Wi-Fi is down.

The long-term care program adds the caution that matters most: “devices are only as effective as the user,” and “no device can replace human oversight.”³ A smart plug is a convenience and a small safety gain, not a monitoring system. If a missed coffee pot would mean a fall went unnoticed, that is a job for a medical alert system.

Where it fits

A smart plug is usually the first step into the smart home and often the only one a person needs. If it goes well, our guides to voice-controlled lights, smart lights, and the Echo Show versus Nest Hub cover the next steps, and smart home privacy covers what these devices hear.

Key takeaways

• A $15 smart plug makes any lamp voice-, phone-, or schedule-controlled.
• Four jobs: bedside lamp by voice, lights at dusk, the morning coffee routine as a quiet check-in, lights while away.
• Never a space heater. Heaters go straight into the wall and get switched by hand; they cause 88 percent of home heating fire deaths.
• 15 amps, 1,800 watts: fine for lamps and a coffee pot, not for anything that heats for hours, and never the stove.
• Set it up yourself, name plugs plainly, test by voice, and show the manual button.

What’s next

• Light the night route: lighting for aging eyes.
• Go a step further: set up voice-controlled lights.
• For the stove, not a plug: automatic stove shut-off devices.
• Space heaters done safely: winterizing a senior’s home.
