The DB3 doorbell uses the TTLock app — look for this logo in the app store. It is added through the Camera menu: tap the menu icon in the top-left, select Camera, then Add Camera and DB3. Do not use Tuya or Smart Life for this product unless Blusafe confirms otherwise.
Step by step
Set up & install
Work through each task in order — add the doorbell to the app first, then mount it and pair the chime. Tick the steps as you go; your progress is saved on this device.
Troubleshooting
Fix a problem
Most DB3 setup problems come down to 5GHz Wi-Fi, a battery that needs charging, or a doorbell that needs a quick factory reset — not a faulty unit.
