You got the keys, signed the papers, and the house is officially yours. The previous owners left behind some smart home gear: a Nest thermostat, a Ring doorbell, maybe a smart lock. Looks like a bonus. Could be a security problem.

Here's the issue: those devices are still registered to whoever lived there before. That means they may still have remote access. They can see if motion was detected at your front door. They can check what temperature your house is set to. In some cases, they can still unlock the door.

This post gives you a room-by-room checklist for resetting every common smart home device before you get comfortable in your new place.

Start With the Router

Everything else on the network depends on this. If you kept the previous owner's router, do a factory reset first. Usually there's a small pinhole reset button on the back. Hold it for 10 seconds. Then set a new network name and password that you create yourself.

If you're using your own router, set it up fresh. Don't use the default admin password that came in the box. Change it immediately.

Smart Doorbells and Security Cameras

Ring, Nest, Arlo, Eufy: these all require an account to view footage. If the previous owner never removed their account, they may still be able to see your front door.

For Ring: hold the setup button on the back for 15 seconds until the light flashes, then set it up fresh in the Ring app.

For Nest cameras: press and hold the button on the back for 10 seconds. You'll see the light turn solid for a few seconds, then go off.

For any other camera, check the manufacturer's app for "factory reset" instructions. Always assume an old account exists until you confirm otherwise.

Smart Locks

This one matters most. A Yale, Schlage, or August smart lock that still has the previous owner's codes is a real problem.

The reset steps vary by brand, but most involve holding a button on the interior side and entering an admin code. Once reset, every code and account access is wiped. Then you set up your own account and create new codes from scratch.

If you can't find reset instructions and there's a brand label on the lock, just search "[brand name] smart lock factory reset" and you'll find the official steps in under a minute.

Smart Thermostats

A Nest or Ecobee doesn't carry the same risk as a lock, but the previous owner's schedule, preferences, and billing integrations might still be active.

Go to settings in the thermostat's app and look for "factory reset" or "reset all settings." On a Nest, that's Settings, then Thermostat, then Reset, then All Settings.

Smart Speakers and Displays

Amazon Echo and Google Home devices are linked to accounts. If an Echo is still on someone else's Amazon account, they can potentially control it and may be able to hear audio.

Deregister it from your Amazon or Google account portal first, or do a factory reset on the device itself. On an Echo, press and hold the mute and volume-down buttons at the same time until the orange light ring appears.
