Using TTLock Without a Gateway: What Still Works

• The lock added to your account once, which does need an internet connection at setup time even though daily use afterwards is offline-capable.
• A phone with Bluetooth for every in-person interaction: unlocking, adding users, and pulling logs stored on the lock itself.
• No gateway at all if you only need local access — passcodes, cards, fingerprints and Bluetooth eKeys do not depend on one.

1. Passcodes. Permanent, temporary and recurring passcodes can be created and entered on the keypad without any gateway involved; the lock validates them itself.
2. Cards and fingerprints. These are enrolled directly on the lock via the app over Bluetooth and are checked locally by the lock's own hardware.
3. Bluetooth eKeys. Sharing an eKey with someone else's app account works over the internet at the moment of sharing, but using it to unlock afterwards only needs Bluetooth range.
4. Local unlock records. The lock keeps a log of who unlocked it and when in its own memory, which the app can read the next time it connects over Bluetooth.
5. Manual key override, if the lock model includes one, works independently of any electronics at all.

Without a gateway, records still exist on the lock, but they only reach the cloud and your history view once a phone with the app connects over Bluetooth and pulls them. That means the log can lag behind real events if nobody opens the app for a while.

• Buying a gateway before confirming it is actually needed. If nobody needs remote unlock or instant remote logging, a Bluetooth-only setup is simpler and has one less device to maintain.
• Expecting the app's online/offline indicator to be accurate without one. Without a gateway the app cannot ping the lock in real time, so that status is generally unavailable or based on the last Bluetooth connection.
• Assuming eKeys need a gateway to be shared. Sharing itself happens over the internet through the cloud account system; only using the eKey requires Bluetooth proximity, not a gateway.
• Not checking activity logs regularly. Without a gateway keeping the log current automatically, records only update when someone's phone connects and syncs them.
