The same 39 smart devices crossed two closings. Both times, they became new information.
A month ago on LinkedIn, I wrote about our client's seller who counted the smart devices in his own home and arrived at 44.
His own network data contained 83.
The 39-device difference mattered. But what happened next revealed the larger problem.
The house sold. Later, a couple years or so, that buyer became the next seller. The same 39 devices passed through a second closing and became someone else’s problem again.
The record existed.
Nothing carried it forward.
The second closing did not begin with 39 missing devices
It began with an unknown number.
Thirty-nine is only what we could prove when the first owner left. Nobody maintained a property-associated record of what the next owner added, removed, replaced, disconnected, or reconfigured during the years that followed.
A video doorbell here. A smart plug there. A new thermostat. A camera purchased during a holiday sale. A hub installed with one system and later connected to several more.
By the second sale, the actual number of connected devices inside the home was unknowable.
That is the real infrastructure gap.
One overlooked camera is an incident. One forgotten lock is a closing problem. But when a transaction lacks a durable record, the parties cannot even determine the size of the connected environment they are trying to transfer.
Without a record that survives ownership, every closing starts from zero.
Pennsylvania recognizes the issue—but assigns the burden backwards
Pennsylvania’s standard Agreement of Sale contains language addressing smart devices. Section 10, Paragraph H requires the seller, on or before settlement, to make a reasonable effort to clear all data stored on IoT devices located on the property and included in the sale. It also requires the seller to disconnect personal devices that can connect to them, clear relevant data, and make no attempt to access the remaining IoT devices after settlement.
Then the burden shifts.
Following settlement, the buyer must make a reasonable effort to clear the stored data again and restrict access by the seller, the seller’s agents, and any third party previously given access. The clause specifically contemplates restoring devices to original settings, changing passwords or codes, updating network settings, and submitting ownership and contact changes to manufacturers and service providers. The provision survives settlement.
Recognizing connected devices in the contract is important. Requiring the seller to disconnect and clear access is appropriate. But the post-settlement burden exposes a fundamental problem.
The seller knows what was installed. The seller knows which applications were used, which accounts exist, which subscriptions may be active, who was granted access, and which devices were added over time.
The buyer knows none of that.
Yet the buyer is asked to remediate an environment they did not create and cannot fully see. The standard is framed around reasonable effort, but the transaction still lacks a defined evidentiary standard for what was identified, what was cleared, what was transferred, and what remained unresolved.
That is backwards.
A buyer should receive a clean slate—pun intended—not a post-closing investigation and a manufacturer-by-manufacturer to-do list.
This does not mean a seller should be accused of retaining access. It means the transaction should not rely on an assumption when the relevant systems can affect privacy, physical security, and control of the home.
Real estate does not ordinarily accept important claims without evidence. Inspections create findings. Appraisals create valuations. Title work creates a record of ownership and encumbrances.
The connected transition should create evidence too.
The work had already been done
At the first sale, the seller completed the inventory device by device. He did it honestly. We also had video documenting how the initial connected-home handover went wrong.
The transaction produced information.
What it did not produce was continuity.
The inventory became a spreadsheet—a file in a folder on someone’s laptop. We sent it to the seller. Nothing in the next transaction required anyone to find it, recognize it, or treat it as part of the property’s continuing record.
A record with no home and no standing is just an attachment.
That was February 2024, and at the time it was the state of the art we could reasonably deliver. The devices had been operating inside the property all along. What did not yet exist was a persistent identity capable of carrying their structured record beyond the transaction that created it.
That limitation changed what we decided to build.
We stopped treating the document as the destination and started building a place for the record to live.
Real estate identifies the envelope extraordinarily well
Consider what the industry already knows how to identify.
Legal descriptions. Block and lot. Metes and bounds. Surveys. Parcel numbers. Assessment records. Deeds.
I have been licensed in real estate for eight years, and I have never written a legal description into an agreement from memory. Nobody does. We reference the parcel, and title retrieves the legal description from the recorded chain.
That substitution is revealing: the industry relies on an identifier because it needs something that resolves consistently.
Those systems describe the envelope. They tell us where the parcel begins, where it ends, and where the structure sits within it.
They do not describe what operates inside the building.
To be fair, the traditional recorded chain works remarkably well. Deeds, liens, easements, and tax history can remain continuous across a century and eight different owners. The record survives because it is associated with something persistent.
There has simply been no equivalent continuity layer for the connected interior of the home.
The property changes hands. The devices often remain. The accounts, permissions, applications, integrations, subscriptions, and administrative control may not transition with them.
Physical conveyance and digital continuity are not the same event.
A modern closing needs a digital transition
The answer is not continuous monitoring. It is not indefinite network access, collection of private content, or a promise that a connected environment will never change.
The answer is a seller-authorized, time-bound, verifiable workflow.
The seller authorizes the observation. Smart Device Fixtures™ visible within that authorized environment are identified and structured. The seller reviews the findings, confirms what stays and what goes, identifies anything that changed or may have been missed, follows necessary protocols to reset, revoke access, and other manufacturer-suggested steps, and attests to each SDF having completed that workflow, and ultimately esigns/verifies the final record near closing.
That creates evidence of what was observed and represented at a defined moment.
But evidence alone is not enough. The first Harrison inventory proved that.
The evidence must resolve to the property, remain available beyond a single transaction file, and preserve continuity as owners, devices, vendors, and platforms change.
The record needs a persistent identity
That problem became four years of work for CleanSL8®.
Our MyHOME ID™ network provides a resolvable identity for more than 130 million U.S. properties, anchored on Ethereum. It was built so that a property-associated record can outlive the transaction that created it.
CleanSL8 creates the authorized evidence and transfer workflow for Smart Device Fixtures. MyHOME ID provides the persistent identity and continuity layer beneath it.
The distinction matters.
A spreadsheet can document one moment.
A persistent identity can connect that moment to the property’s next one.
The goal is not to freeze a home in time. Connected environments will always change. Owners will add devices. Vendors will replace platforms. Hardware will fail. Systems will be removed or upgraded.
Continuity does not require the contents to remain static. It requires each verified change to have somewhere to resolve.
At the first closing, the 39 devices were newly discovered.
At the second closing, they should have been history.
Instead, they became new information again.
That is what happens when the record exists but nothing carries it forward.
Every Home Is Smart, It Just Doesn't Know It Yet.™
CleanSL8® provides seller-authorized, point-in-time workflows for identifying, reviewing, and documenting Smart Device Fixtures™ during a real estate transaction. MyHOME ID™ provides the persistent property identity and continuity layer through which those records can endure beyond a single ownership event.
