Every window, watched.
Standalone Wi-Fi sensor — connects to your home Wi-Fi, not to a lock. No gateway needed.
The DS3 is a standalone Wi-Fi sensor that watches the openings your smart lock can't see: windows, back doors, side gates and any other secondary entry point. It connects directly to your home Wi-Fi and reports open/closed status to the TTLock app, with an alert the moment anything opens.
Because it works over Wi-Fi on its own, there is nothing else to buy — no gateway, no hub, and no lock connection required. Place one on each window or secondary door you want to monitor and check the whole house from a single app.

What's in the box
Works with
The DS3 is managed in the TTLock app, so it sits naturally alongside the Blusafe Origin Smart Plus, Apollo and the DB2 video doorbell — your locks, doorbell and window sensors all in one place. It does not pair with or control a lock.
Frequently asked questions
Will the DS3 trigger auto-lock on my smart lock?
No. The DS3 cannot bind to a lock. If you want the door to lock itself the moment it closes, you need the DS2 Door Sensor, which pairs directly with the Origin Smart Plus and Apollo.
Do I need a Wi-Fi gateway?
No. The DS3 connects directly to your home Wi-Fi, so alerts and status work with no gateway, hub or other hardware.
Where should I use it?
On windows and secondary doors — anywhere you want to know "is it open or closed?" from your phone. Many customers fit one DS3 per ground-floor window alongside a DS2 on the main entrance.
Can I use several DS3 sensors in one home?
Yes — each sensor appears separately in the TTLock app, so you can name them by room and monitor them all from one screen.
