Factory reset is necessary but it is not sufficient, and this is where most sellers get it wrong. You also have to remove each device from your account on the manufacturer's side, or the new owner cannot claim it at all. The agents above are right that you reset the hardware. Here is what that misses. Ring, Google Nest, ecobee and the rest tie the device serial number to your account in their cloud. If you only reset the device locally, the serial can still show as claimed by you, and the buyer gets an error that says the device is already registered. Then they call you, weeks after closing, and you are logging into an account you thought you were done with. So the order is: remove from account first, then factory reset, then hand over the physical device. Do it in this sequence, roughly a week before closing so you have time to fix problems: 1. In each app, delete or remove the device from your account. Ring and Nest both publish a remove-device or transfer-ownership flow. Follow theirs, do not improvise. 2. Cancel or unlink any subscription tied to the device. Ring Protect, Nest Aware, and similar. You do not want to be paying for their doorbell in November. 3. Factory reset the hardware itself. 4. Wipe the smart hub or base station the same way, and remember the ones people forget: the garage door opener, the smart lock, the irrigation controller, the smart thermostat schedule, and the doorbell chime. 5. Reset your Wi-Fi router to factory defaults and set a new network name and password at the very end, after you move out. That is the single biggest security gap and almost nobody does it. 6. Delete saved video clips and the address from the app before you remove the account. Some platforms keep clips tied to the account, not the device. To answer your direct question, no, sellers do not usually uninstall them. Anything hardwired, meaning a doorbell tied to your chime transformer, a thermostat, or a hardwired camera, is generally treated as a fixture and stays. Battery-only cameras sitting on a shelf are personal property and go with you unless you say otherwise. Which brings up the piece nobody mentioned: put it in writing. List each device you are leaving by name in the purchase contract, and list anything you are taking. "Smart home devices" as a phrase is an argument waiting to happen. "Ring video doorbell, Nest thermostat, and two exterior cameras included; two interior cameras excluded" is not. And one courtesy that pays off: leave a one-page sheet on the counter with each device, its model, and where the app is. Buyers remember that, and it costs you nothing. I am Zoltan Peresztegi, a real estate professional in Los Angeles and the South Bay, and I have seen exactly one deal get genuinely tense over this, when a seller could not be reached to release a smart lock. Ten minutes of account cleanup avoids all of it. Zoltan
