The Yale Smart Cabinet Lock can easily be operated locally using the Yale Home app- as long as you're within Bluetooth range.
The Smart Cabinet Lock does not have built in Wi-Fi. If you wish to control your lock remotely (when you're not nearby), you'll need a Yale Connect Wi-Fi Bridge (sold separately). This Bridge connects to your 2.4 GHz Wi-Fi network and communicates with the lock via Bluetooth, enabling remote access through the Yale Home app.
