Here are some of the frequently asked questions about this product

What is the purpose of the Wi-Fi Bridge?

The Wi-Fi Bridge enables you to control, manage and monitor your smart lock remotely using the App on your smartphone. If you don't have the Wi-Fi Bridge, you still can control your lock using the App within the Bluetooth Range.

How does Wi-Fi Bridge work?
Plug the Wi-Fi Bridge into a USB socket or USB power adapter and connect it to your home Wi-Fi in the TTLock app – then it is ready to be paired with your SDL smart door lock. It is recommended to place the Wi-Fi Bridge within 3-7 meters of the lock.
If I buy multiple locks, do I need 1 Wi-Fi Bridge for each lock?
No, a single bridge can be connected to multiple locks given they are all within the recommended 3-7 metre range.
Can I buy the Wi-Fi Bridge later?
Yes. You can buy it at a later date. But it's more cost-effective to buy it as a bundle.
