Wyze Lock no gateway?

On the Wyze lock page it mentions the lock gateway is needed to connect the lock to wifi.

I setup the lock and gateway and everything worked. I then disconnected the gateway and it seems like everything still works.

When I say “everything” I can still lock and unlock from my phone. So that has to mean the lock has internet connectivity despite the gateway not being on.

What am I misunderstanding here?

I don’t have the lock, but I’m pretty sure there’s also a Bluetooth connection too. See if you can unlock and lock it remotely.
