Many lamps have their switch on the cord behind a sofa, under a lampshade, or on the base where reaching it means leaning over a side table. For an older adult, that stretch is a real balance risk, and many simply leave the lamp off and sit in dim light. A smart plug fixes this cheaply. The lamp plugs into the smart plug, the smart plug goes into the wall, and the lamp can then be switched by voice through a smart speaker, by a schedule, or from a phone. This guide explains how to set one up and keep it simple.
How a smart plug works
A smart plug is a small adapter with a relay inside. When you send a command, it switches power to whatever is plugged into it. Connected to your home Wi-Fi, it can be controlled by:
- Voice, through a smart speaker or display: "Alexa, turn on the reading lamp."
- Schedules, such as on at sunset and off at 11 p.m.
- An app, on a phone or tablet, for family members to check or control.
- The button on the plug itself, as a backup.
A plug to consider
The Kasa HS103P2 is a widely sold 2-pack of Wi-Fi smart plugs that work with Alexa and Google Assistant without a hub, with app timers and schedules.
Kasa Smart Plug HS103P2, 2-pack

Pros

Setting it up
- Install the plug maker's app on a phone and create an account.
- Plug the smart plug into the wall near the lamp.
- Follow the app's steps to connect the plug to your Wi-Fi. Most plugs need a 2.4 GHz network.
- Name the plug clearly, such as "reading lamp" or "bedside lamp". Simple names are easier to say.
- Link the app to Alexa or Google Home, if using voice.
- Plug the lamp into the smart plug and switch the lamp's own switch on. Leave it on.
- Test by voice and by the button.
Use schedules
Schedules can make lighting automatic. A living room lamp can come on at sunset so the user never sits in the dark. A bedside lamp can come on at a set wake time. A hallway lamp can stay on low until bedtime. That means fewer commands to remember and fewer trips across a dark room.
Keep it simple
- Use only a few plugs at first, for the lamps that cause the most reaching.
- Use the same naming pattern.
- Group lamps into a room so "turn on the living room" switches all of them.
- Have a family member manage the app, so the user only uses voice or the button.
When Wi-Fi goes down
If the internet or Wi-Fi drops, voice control stops working. Most plugs keep a physical button that still switches power. Show the user where it is. Some plugs remember their last state after a power cut; others default to off. Check yours.
Privacy and security
Smart speakers listen for a wake word. Review the privacy settings in the speaker's app, and mute the microphone if desired when not needed. Use a strong Wi-Fi password and keep the plug's app updated.
Safety
- Check the plug's rated load. Lamps are well within the limits; space heaters and some appliances may not be.
- Do not plug a smart plug into a power strip that is already heavily loaded.
- Keep cords out of walkways.
- Use plugs listed by a recognized testing lab.
Other hand- and reach-friendly changes
Smart plugs remove the need to reach lamp switches. Other small changes help hands and reach too: lever converters on round doorknobs, rocker light switches, and reachers for dropped items. See our guide to doorknob to lever converters.
Smart bulbs vs smart plugs
Smart bulbs screw into the lamp and can dim and change color, which is useful for a soft night setting. But if someone turns off the lamp's own switch, the bulb goes offline. Smart plugs keep working with any bulb and any lamp, and the lamp switch is left on. For simplicity, many families start with plugs.
Who benefits most
Smart plugs suit people who use a smart speaker comfortably, or who can rely on schedules. They suit people with limited reach, arthritis, a walker, or low vision. For someone who finds voice commands confusing, schedules alone still help.
Helping a parent get used to it
Set up the plugs during a visit, then practice the commands together a few times. Start with one or two lamps, and add more only once the first ones feel natural. Put the smart speaker where it can hear the user from their usual chair and from the bed. If the user forgets the exact wording, add alternative phrases in the voice assistant's routines so "turn on my lamp" and "lamp on" both work. Check in after a week to see what is used and what is ignored, and remove anything that causes confusion.
Family members can also use the app to check that lamps were switched on in the evening, which some families find reassuring when they live far away. Agree with the user on what you will and will not check, so it feels helpful rather than intrusive.
Keep the plug's packaging and setup code until everything works, since you may need the code to reconnect the plug after a router change.
FAQ
Do smart plugs need a hub?
Many Wi-Fi plugs, including the Kasa HS103, work without a hub. They connect to your router directly.
Can I control a lamp by voice without a smart speaker?
You can use a phone's voice assistant with the plug's app, but a smart speaker is easier hands-free.
What happens to a smart plug in a power cut?
It switches off with the power. When power returns, behavior depends on the plug's settings.
Can smart plugs work with any lamp?
Most lamps work, as long as the lamp's own switch is left on.
Are smart plugs safe to leave plugged in?
Yes, when used within their rating and listed by a testing lab.
