[Smart Lock] A person anxious about whether they locked the door investigates how SwitchBot works.

What is a smart lock?
I have summarized this from the perspective of Hana, who bought one because I was too worried about forgetting to lock the door, covering everything from why it can be installed in rental properties to how to check it while away.

Did you lock the door?.

I am the kind of person who probably turns back twice a week.
I walk five minutes toward the office, then think, "Wait, did I lock the door?"
When I go back, it is locked.

Of course it is. I have had the habit of locking doors for ten years.

But anxiety does not disappear just by verifying the facts.
It seems that is just the nature of my brain.

SwitchBot Smart Lock is the reason I bought it.
It is not because "I longed for a smart home."
It is because "I wanted to be able to check it with an app while away."

As a purchasing motive, it is too plain (though that is to be expected).

To begin with, I did a little research on why I feel anxious.

Anxiety about forgetting to lock the door is sometimes explained in the context of cognitive science as
"residual attention to incomplete actions."
In other words, it is a state where the brain repeatedly sends the question, "Did I really finish this action?"

The problem is that the more the action of "going back to check" is reinforced, the harder it becomes for the anxiety to disappear.
The more you accumulate experiences of relief, the more your brain demands verification.

Therefore, changing to a "structure where you can check it instantly with an app" is not a detour. There is a basis for it.

The mechanism was simpler than I thought.

To put the operating principle of the SwitchBot Smart Lock in one word, it is a
"device that turns the thumbturn electrically."
It is the part on the inside of the front door that you pinch and turn with your fingers.
You cover and secure the device over that thumbturn.
The internal motor rotates the thumbturn left or right, which locks or unlocks the door.

That is all.
Even though I was researching cutting-edge technology,
the structure was surprisingly physical.
It might be the same principle as a sewing machine (that is too much of a metaphor).

The reason it requires no construction is also here.
It does not modify the existing lock at all.
It does not drill holes in the door.
Since it is a machine that just grabs and turns the thumbturn,
securing it with strong double-sided tape works.

The reason it can be used in rentals is literally just that.
The official site says it is compatible with "about 99%" of doors.

They are full of confidence.

Installation was a one-shot deal with double-sided tape.

Choose the included adapter to match the size of the thumbturn.
Check the position with the paper template sticker.
Apply the double-sided tape to the main unit and press it on slowly.

The problem is that you cannot afford to fail.
The double-sided tape is a one-shot deal. You can't re-stick it.

I took a deep breath and stuck it on. It worked.

But for that one moment, I was more nervous than in an escape room.

After installation, I connected it to the app and moved the motor, and the thumbturn turned on its own.
It's only natural, but honestly, I was quite surprised the first time I saw it.

It took a little while to get used to the sight of my own front door lock turning by itself.

Things that changed after using it, honestly.

The biggest change is the number of times I've had to turn back.

This sense of security was far greater than I expected.

However, for checking from outside and remote operation, you need a separate
SwitchBot Hub Mini.The lock alone only works within Bluetooth range (within a few meters).
If you want to check from the office, you should think of it as a set with the hub.

Before I knew it, I was even researching the specs of the SwitchBot Hub Mini. It's a product that acts as a "
relay" to operate the lock via Wi-Fi from outside, and this one device allows for remote locking.

As I researched further, I noticed the existence of a fingerprint authentication pad.
You don't need a smartphone or a physical key; you can open it with just one finger.
The completed form of a keyless life was right there.

Things I was concerned about, I won't hide them.

I set up the auto-lock feature, but disabled it after a week.
The door locked automatically while I was taking out the trash.
I was locked out without a key.
Knowledge and experience are two different things.

The difficulty of removal is also high.
Because it is fixed with double-sided tape,
it takes a fair amount of force to peel it off.
If you are renting, it is safer to check with the management company in advance about how to handle it when moving out.

One more point.
There is a time lag of about 0.5 to 1 second for app unlocking.
I think people are clearly divided into those who mind it and those who don't.
I was in the group that didn't mind, but my companion would always make a subtle expression during that time (that person is still a physical key person).

The time I spent researching was shorter than the time I spent turning back.
That alone was enough.

There is a basis for this. Hana
