Frequently Asked Questions
Q: Does the TTLock DS2 door sensor work with all TTLock smart locks?
A: The DS2 is compatible with all TTLock smart devices that include the "Add Door Sensor" option in their settings menu. Always verify your specific lock or gateway model supports this feature before purchasing. It is confirmed to work with the TTLock G2 gateway.
Q: Does the DS2 door sensor work on its own without a TTLock device?
A: No. The DS2 must be paired with a compatible TTLock smart device (such as the G2 gateway). It cannot operate independently and requires the TTLock App ecosystem to communicate status updates to your smartphone.
Q: What battery does the TTLock DS2 use, and how long does it last?
A: The DS2 uses a standard CR2032 3V button battery. Thanks to its ultra-low standby current of less than 5µA, the battery can last up to 2 years under typical usage. Note that the battery is removed during shipping due to carrier restrictions — you will need to insert one before first use.
Q: Can the DS2 trigger my smart lock to lock automatically when the door closes?
A: Yes! When used with a compatible TTLock smart lock that has an auto-lock function, the DS2 can trigger automatic locking as soon as the door is detected closed. This feature is only available if your lock model supports auto-lock.
Q: What is the maximum gap between the sensor and magnet for reliable detection?
A: The DS2 reliably detects open/closed status when the gap between the sensor body and its magnet is less than 22mm. For best results, install both pieces as close together as possible on your door or window frame.
