A Bluetooth lock is integrated with a Bluetooth module or Bluetooth chip to enable internet connection.
Tuya’s Bluetooth lock solutions support two types of connection.
Both connection types require integration with the Tuya Bluetooth lock protocol. There are two options to achieve this purpose.
These two integration methods are performed on the device side with different protocols.
Tuya Bluetooth lock solution supports the following features.
|End-to-end encryption||Data is encrypted and secured when it travels across the mobile app, server, and Bluetooth module.|
|Unlocking record||An unlocking record contains the unlocking method, unlocking ID, and unlocking time. The user can check the unlocking records for the last 6 months from the mobile app. A combination of unlocking methods is supported, such as fingerprint plus password.|
|Cache unlocking records||Cache the unlocking records on the Bluetooth module or chip and synchronize them with the mobile app when the lock connects to it.|
|Alert||An alert is sent to the user in any of these cases: low battery, wrong attempts by passwords, fingerprints, or cards, prying lock, and high temperature.|
|Time synchronization||Synchronize the clock on the lock with a time server. Global time zones and daylight saving time (DST) are supported.|
|Member management||The user can add lock members using the mobile app.|
|Battery level||Display battery percentage or status.|
|Unlock via mobile app||The user can unlock the door using the mobile app when the mobile phone is connected to the lock over Bluetooth.|
|Dynamic password||The Bluetooth module is integrated with dynamic password algorithms. The user can get dynamic passwords that are valid for five minutes using the mobile app.|
|Add unlocking methods||When connected to the lock via Bluetooth, the mobile app allows the user to add or delete unlocking methods, such as fingerprints, cards, and passwords.|
|Temporary password||If the hardware supports local RTC, the lock administrator can set a validity period and temporary password for non-home member users. However, the validity period and temporary password do not apply to home member users.|
|Validity period||The lock administrator can specify the validity period of a user on the mobile app.|
|OTA update||Update the firmware on the module and the MCU via OTA.|
|Offline temporary password||The offline temporary password does not rely on an internet connection. The algorithms are implemented by the module and the cloud. The MCU calls the specified API to verify the temporary password.|
|Lock status||The user can check the lock status on the mobile app, such as double lock and child lock.|
|Auto-locking||Enable or disable auto-locking.|
|Auto-locking delay||The user can set the time before the lock gets locked.|
|Synchronize unlocking methods||When directly connected to the mobile app, the lock synchronizes the unlocking methods with the cloud.|
|Voice commands||The mobile app sends the collected voice commands to the lock.|
The Bluetooth lock solution supports the following categories.
|Bluetooth residential lock||It is the standard Bluetooth lock solution, with a full set of smart lock features that can be tailored to your needs.|
|Bluetooth safe box||Support Bluetooth safe box solution.|
|Bluetooth lock accessory||Apply to common lock accessories such as key fobs and password panels.|
|Bluetooth small lock||Apply to cabinet locks, U-locks, and key boxes.|
