You can use the Freestyle Trilock as a stand-alone unit via keypad or app within Bluetooth distance from the door, without the Wi-Fi Bridge. If you want the full functionality such as remote access anytime, anywhere, alerts when other household members have arrived home, alerts when the door has been compromised, you will need a Gainsborough Freestyle Wi-Fi Bridge and Door Sensor kit.
The Wi-Fi Bridge allows you to connect your Freestyle Trilock to your home’s Wi-Fi network so you can access your lock remotely and receive alerts on who has accessed the house.
The Door Sensor allows you to view the status of your door. You may have locked the door remotely, but your door may have been left ajar!
