How to use

Monitor unlock history and manage family or guest access from the app as needed.
Usage recommendations
To ensure reliable operation, use recommended CR123A alkaline batteries and replace them before the low-battery warning depletes. For consistent fingerprint recognition, enroll fingerprints cleanly and avoid registering damaged or excessively worn fingerprints. Verify BLE and Tuya app compatibility with your mobile device before installation.
