Smart Home Device Disconnect Checklist

Protect your privacy and set up the new owners for success before you hand over the keys.

Smart homes are great until you sell one and forget to disconnect everything. Leaving your devices linked to your accounts is a real privacy risk, and it creates a headache for the buyers trying to set up their new home. Work through these four steps before closing day.

Step 1: Make a List

Walk your home inside and out and inventory every smart device you have. Don't forget the ones you rarely think about. Here's what to look for:

• Front Door: Smart locks. Note the last known code and how to reprogram.
• Thermostats: Nest, Ecobee, etc.
• Security Systems: Doorbell cameras, security cameras, motion sensors, alarm pad codes
• Lighting: Smart light switches, smart bulbs, automated blinds and shades
• Appliances: Smart refrigerators, ovens, washers, and dryers
• Hubs & Voice Assistants: Amazon Alexa (Echo), Google Home, Apple HomePod
• Garage Door Openers: Smart garage door controllers
• Irrigation/Sprinkler Systems: Smart water controllers (e.g., Rachio)
• Entertainment: Smart TVs, speakers, and home theater systems
• Other: Smart plugs, air purifiers, or any other Wi-Fi or Bluetooth-connected device

Step 2: Disconnect & Reset: Protect Your Privacy

The goal is to hand over a clean, factory-reset device the new owners can set up from scratch. For every device on your list:

• De-register from your account: Open the app for each device and find the option to "de-register," "unpair," or "remove device."
• Factory reset: Perform a factory reset on the device itself, not just in the app.
• Change passwords and Wi-Fi: Reset passwords on any device you are leaving behind.
• Cancel subscriptions: Security monitoring, cloud storage for cameras: cancel or transfer these before closing.
• Clear all data: On smart refrigerators, clear any personal info stored on the screen and cancel any food delivery accounts linked to it.

Step 3: Leave Instructions for the New Owners

A little documentation goes a long way. You don't need to write a manual, just leave enough that the buyers can get everything running without calling a tech support line on move-in day.

• Create a simple document: A Word doc or email works fine. List each device, its location, and the app they'll need to download.
• Provide setup instructions: Tell them which app(s) to download to manage the home.
• Leave the manuals: If you still have original boxes and user manuals, leave them on the kitchen counter.

Step 4: The Final Check

Before you leave the home for the last time, do a final sweep to confirm your personal data is completely gone.

• Check the Wi-Fi: Is your personal network name still being broadcast from a router you're leaving behind?
• Check the hubs: Are your voice assistants or smart hubs still responding to your voice commands?
• Confirm one last time: Open your apps and verify all devices have been fully removed from your account.
