DS2 Door Sensor
Pair your DS2 door sensor with your lock in the TTLock app, stick it to the door, read the LED signals, replace the battery and fix the most common setup issues — without opening the PDF.
- Manual version
- V2026.1
- Correct app
- TTLock
- Setup time
- 15–25 minutes
The DS2 works with your Blusafe TTLock smart lock — look for this logo in the app store. The sensor is added through the lock's Settings → Door sensor menu, so add your lock to the app first. Do not use Tuya or Smart Life for this product.
Step by step
Set up & install
Work through each task in order — pair the sensor in the app first, then stick it to the door. Tick the steps as you go; your progress is saved on this device.
Troubleshooting
Fix a problem
Most DS2 issues are pairing timing, a gap wider than 22 mm, or a tired CR2032 battery — not a faulty sensor. The LED tells you most of what you need to know.
