You changed the locks. You updated the alarm code. You feel secure.
But there's a good chance the previous owner can still see who's at your front door, check your thermostat, and unlock your house — and they don't even have to try hard.
Smart home devices don't automatically forget their previous owners. Unless someone explicitly removed the device from their account and factory reset it, access often transfers right along with the house.
This is more common than people realize, and it's worth taking seriously.
Why This Actually Happens
When someone sells a home, they're usually juggling a hundred things. Cleaning out closets, coordinating movers, handling paperwork. The smart devices on the wall aren't top of mind.
Most smart home devices tie to a cloud account. That account is tied to an email address. Unless the previous owner logs into every device, removes it from their account, and performs a factory reset — the connection remains. Their phone still controls the thermostat. Their app still shows your camera feeds. Their app might still unlock your front door.
This isn't paranoia. It's how the technology works.
Devices to Check When You Move In
Smart Locks (August, Schlage Encode, Yale Assure)
Smart locks are the most obvious risk. If the previous owner never removed the lock from their August or Schlage app, they likely still have access. Some locks also retain access codes programmed directly into the device.
What to do: Factory reset the lock and re-pair it to your own account. For most smart locks this involves holding a button on the lock body while it's removed from the door. Check the specific manual for your model.
Security Cameras (Ring, Arlo, Nest Cam)
Ring, Arlo, and Nest cameras all connect to cloud accounts. If the previous owner didn't remove the devices from their Ring or Google account, they may still receive motion alerts and can still view live feeds.
What to do: Factory reset each camera and set them up fresh with your own account. For Ring cameras, hold the setup button on the back until the light flashes. For Nest, use the device settings menu to reset to factory defaults.
Video Doorbells (Ring, Nest Hello, Eufy)
Same as cameras — these live in someone else's account until explicitly removed. The previous owner could literally see every time you come and go.
What to do: Same process as cameras. Factory reset, create your own account, add the device fresh.
Smart Thermostats (Nest, Ecobee)
Nest and Ecobee thermostats are tied to Google and Ecobee accounts respectively. If the previous owner didn't remove the thermostat from their account, they can still adjust your home's temperature remotely.
What to do: On a Nest, go to Settings > Reset > All Settings. On an Ecobee, go to Main Menu > About > Register. Both will guide you through re-pairing to your own account.
Smart Speakers and Displays (Amazon Echo, Google Home, Apple HomePod)
Smart speakers are often left behind or forgotten. A Google Home or Echo that's still tied to someone else's account can be used for voice commands, smart home control, and accessing music/shopping accounts.
What to do: Factory reset any smart speakers you find. For Echo, hold the action button for 25 seconds. For Google Home, hold the microphone mute button for 15 seconds.
Smart Home Hubs (SmartThings, Hubitat, Wink)
Hubs coordinate multiple devices. If a SmartThings hub is still on the previous owner's account, it may have control over every smart device in your home — lights, locks, sensors, everything.
What to do: SmartThings requires removing the hub from the account in the app, then pressing the reset button on the hub itself. Hubitat has a similar process through the admin panel.
Garage Door Openers (Chamberlain myQ, LiftMaster)
If your garage opener connects to a myQ account, the previous owner's app may still open your garage. This is one people almost always miss.
What to do: Log into the myQ app using your own account, or use the manual controls on the opener to reset and reprogram. Check the manual for your specific model.
The DIY Checklist
Go through each device methodically:
- Identify every smart device in the home (check closets, attic, garage, utility room — hubs hide in strange places)
- Factory reset each device before setting it up with your own account
- Change Wi-Fi passwords after resetting devices (to ensure any forgotten devices can't reconnect)
- Create new accounts on all platforms with your own email
- Enable two-factor authentication on every account
This takes a few hours if you know what you're doing. It can take a lot longer if you don't.
Where DIY Falls Short
The checklist above covers the obvious devices. Here's what gets missed:
Hidden hubs and bridge devices. Z-Wave and Zigbee hubs sometimes hide in server closets, attics, or mounted behind panels. If you don't know they exist, you can't reset them.
Cloud account complications. Some devices can't be fully reset without the previous owner's account credentials. If the prior owner didn't formally transfer or remove the device, you may need to contact the manufacturer to prove ownership of the property.
Devices you don't recognize. If a previous owner was into smart home tech, there may be sensors, switches, and controllers you don't even recognize as smart devices.
Network-level access. If the previous router is still in use and the previous owner knew the admin password, they potentially have network-level visibility even after you change the Wi-Fi password.

Frequently Asked Questions
How do I know if the previous owner can still see my security cameras?
If the cameras weren't factory reset and removed from the previous owner's account before you moved in, they likely still have access. The only way to be sure is to factory reset each camera and set it up fresh with your own account.
Should I factory reset all smart devices when moving into a new home?
Yes, always. Smart home devices retain their previous account connections until explicitly removed. A factory reset and fresh setup is the only way to guarantee you have exclusive control.
Is there a service that audits smart homes for new homeowners?
SageTech offers a New Homeowner Smart Home Audit where a local tech comes to your home, inventories all smart devices, and resets and re-provisions everything to your accounts. Available in Winston-Salem and the Piedmont Triad area through the SageTech app.
Can a previous owner access my smart lock after I move in?
If the lock wasn't removed from their account and factory reset, yes. This applies to August, Schlage Encode, Yale Assure, and most other connected smart locks. Factory reset the lock before pairing it to your own account.
What if a smart device won't reset without the previous owner's account?
Contact the manufacturer directly with proof of property ownership (closing documents, utility bills). Most manufacturers, including Ring, Google/Nest, and Chamberlain, have a process for transferring device ownership when the previous account holder is unavailable.
