How to Set Up Smart Devices With a Disabled User

Why this matters

For someone who cannot reach the door, turn a key or get to a light switch from bed, a smart lock, a video doorbell and a few lighting scenes are not gadgets, they are the difference between waiting for help and letting it in. The same devices set up for the family member who ordered them instead of the person who lives with them become one more thing that does not work: a voice command the user's speech cannot trigger, an app on a phone they cannot hold, a lock that strands them outside. This HowTo is about setup as an access job. The devices themselves are covered in the ConnectedHome articles; read those for how a given device works and fails.

Before you start

Electrical work in this job is real electrical work. Replacing a wall switch with a smart switch, adding a doorbell transformer or wiring a lock's power supply means opening a box on a live branch circuit. De-energize at the breaker, then prove the box dead with a tester checked on a known live source before and after, per NFPA 70E Article 120 (120.5 in the 2021 edition, renumbered in 2024), with work practices at 29 CFR 1910.333(b)(2), done by a person qualified for it. If nobody on the crew is qualified for line-voltage work, that part goes to an electrician.

Plumbing work is real plumbing work. An automatic water shutoff valve on the main means shutting the main, relieving pressure at a low fixture, and cutting into the supply. See related: Installing and Testing an Automatic Water Shutoff.

Nothing in setup or training triggers a live system. If a lock, a leak sensor or a door contact reports to a monitored alarm, call the monitoring center and have the account placed on test before you set anything off, and take it off test when you leave.

The steps

1. Start from the tasks, observed with the person, not from a device list. Sit with the user and ask what they cannot do now that they want to do on their own, then watch them try the ones they can partly manage. Typical answers: let the aide in at nine, lock up at night, turn the lights on before getting out of bed, know who is at the door, turn off water they cannot reach. Write the list in their words. Skip it and you install what the family ordered, which may solve a problem the user does not have and miss the one they do. See related: The Accessibility Walkthrough With the Person Who Lives There.

2. Find the input the person can actually use, and test it before you commit. The options are voice, a large-button remote or switch, a tablet mounted on the chair or bed, a phone app, or automation that needs no input at all (a schedule, a motion trigger). Each has a body behind it. Voice assistants mishear speech that is slow, quiet or slurred, and they fail when the person is tired at the end of the day, which is exactly when lock-up happens. Phone apps need a grip and fine pointing. Have the person try the input you are considering on a device they already own, ten times, at the time of day it will be used. Skip it and the setup works in your demo and fails on Tuesday evening.

3. Prefer devices that keep working when the internet does not. A lock or a lighting scene that only runs through a cloud service stops when the router or the provider is down. For access tasks, choose devices with local control or a local hub where the choice exists, and know which of the user's tasks depend on the cloud. See related: Cloud, Local and Hub-Based Devices. Skip it and the user is locked out of their own front door by an outage they cannot see.

4. Keep every manual control working. Use a smart switch rather than a smart bulb on a circuit the user or family will also flip by hand, because a smart bulb behind a switch turned off is a dead bulb. Keep the physical key cylinder on a smart lock and the inside thumb-turn usable by the person, or replace a hard thumb-turn with a lever-style one if the lock allows it. When a smart switch goes in, put the cover plate on before the breaker closes, stand to the side of the panel as you close it, and confirm the switch both turns the light on and off from its own paddle and from the app. Skip it and the first visitor who flips the switch off disables the user's whole lighting setup.

5. Set the lock's behavior with the user, not at the default. Auto-lock after a short delay is the factory habit, and for a wheelchair user who rolls onto the porch to get the mail, it is a lockout. Decide with them whether auto-lock is on, how long the delay is, and whether the lock announces itself. Issue separate keypad codes or app credentials for the aide, each family member, and an emergency code, so one can be withdrawn without changing the others. Skip it and you have one shared code that everyone has given to someone.

6. Plan for the person who comes in an emergency. Paramedics cannot use an app. Talk with the user and family about a code-operated key lockbox registered with the local fire or EMS service where that service runs such a program, or an emergency keypad code kept with a trusted neighbor. The decision about who holds access to the house is the user's. See related: the Safeguarding articles on family dynamics and access, which this card does not re-cover.

7. Put the doorbell where the person is. A video doorbell that only rings the phone is useless to someone who cannot pick the phone up quickly. Route it to a tablet or a display mounted where the user spends the day, test two-way talk at the volume they need, and for a user with hearing loss add a visual alert. See related: Alerts for a Customer With Hearing Loss; Doorbell Transformers and Why Video Doorbells Fail.

8. Build lighting scenes around movement at night. The scene that matters most is the path: bed to bathroom at low brightness, triggered by voice, a bedside button or a motion sensor at floor level. Set it, then have the person do the trip with it while you watch. Skip it and the brightest scene is the one they use at two in the morning.

9. Give every task a backup that does not need a phone. Write it down task by task: the lock has a key and a keypad; the lights have wall switches; the water valve has a manual handle the user or a neighbor can reach; the doorbell still chimes. Then, with the household's agreement, turn the router off for ten minutes and run every task; if a medical alert or alarm communicator in the house reports over the internet, confirm it has a cellular path first or skip this test. Power the router back up and confirm every device reconnects before you leave. Skip it and the backup exists only in your head.

10. Train at the person's pace, then leave a card. Have the user do each task twice without your hands on anything. Leave a printed card in large type with each task and its backup, without the codes on it. Skip it and the family becomes the help desk, which is often the dependence the setup was meant to remove.

11. Put the accounts in the user's name. The devices should be owned by the user's account, with family members invited as shared users, never by the shop's account or a technician's phone. Record which account holds what. See related: Leaving a Device Record the Next Tech Can Use.

Worked example: a power chair, a front door and an aide at nine

The customer is 66 and uses a power wheelchair. He can press a large button with his knuckle but cannot pinch a key or work a phone screen reliably. His speech is clear. His wife leaves for work at seven and the home aide arrives at nine, so for two hours he is alone, and today the aide waits on the porch until a neighbor lets her in.

Step 1 produced three tasks: open the front door for the aide, lock up after she leaves, and turn on the bedroom and hallway lights from bed. Step 2 tested his input:

TECH:     Try "turn on the hallway" a few times for me.
CUSTOMER: Turn on the hallway.
TECH:     That's 9 out of 10. Same thing in the evening
          when you're tired - is your voice any different?
CUSTOMER: Quieter. My wife has to lean in.
TECH:     Then we put a button by the bed as well, so
          the lights don't depend on the speaker
          hearing you at night.
CUSTOMER: And the door?
TECH:     Voice can unlock a door only with a spoken
          PIN on most setups. Want to try it, or would
          you rather the aide have her own keypad code
          and you just watch her on the tablet?
CUSTOMER: Her own code. I don't want to shout a PIN.

So the door became a keypad lock with an individual code for the aide, a code for his wife and an emergency code, auto-lock set to 3 minutes after the door closes rather than 30 seconds so he can roll out to the porch and back, and the doorbell routed to a tablet on an arm at his chair. The lights became two smart switches (hallway and bedroom) plus a large bedside button, chosen over voice-only after the 9 in 10 day result and his own report that his evening voice is quieter. The lighting hub runs locally, so the bedside button still worked when the tech turned off the router during step 9. The door's tablet view did not: the video doorbell is cloud-only, so with the internet down he cannot see who is there. The tech wrote that on the card, along with the backup: the aide uses her keypad code whether or not he sees her.

Training: he unlocked the door from the tablet twice and turned the night path on from the bedside button twice. The card went on the fridge with the tasks and backups listed and no codes.

How to verify you got this right

Come back, or call, after a week. Ask the user, not the family, which task he did on his own and which one he gave up on. A task he gave up on is the setup failing, not him. Then check the record: every task has a backup that does not need a phone, every device is on his account, and every credential can be withdrawn without changing the others.
