Closes. Locks. Done.
Pairs directly with your lock via Bluetooth — no gateway needed for auto-lock.
The DS2 is a wireless Bluetooth door sensor that pairs directly with your Blusafe Origin Smart Plus or Apollo. It tells your lock the moment the door closes, so the lock can secure itself automatically — and it shows you, in the TTLock app, whether your door is open or closed right now.
It is the single accessory we recommend to every smart lock owner. Stick-on installation takes minutes, the battery lasts around two years, and it works whether or not you have a Wi-Fi gateway.

Blusafe Origin Smart Plus, Blusafe Apollo, and any TTLock smart lock that supports door sensors. Auto-lock triggering requires a lock with an auto-lock function — both the Origin Smart Plus and Apollo qualify.

Frequently asked questions
Do I need a Wi-Fi gateway for the DS2 to work?
No. The DS2 pairs with the lock over Bluetooth, so auto-lock on close works with no gateway at all. A gateway (G2, G5 or G6) is only needed if you want door status alerts while you're away from home.
Will it trigger auto-lock on my lock?
Yes, provided your lock has an auto-lock function — the Origin Smart Plus and Apollo both do. Enable auto-lock in the TTLock app and the DS2 tells the lock the instant the door closes.
How is it fitted?
The main unit sticks to the door frame and the magnetic strip to the door (or vice versa), keeping the gap under 22mm when closed. No drilling required.
