From what I've read you can't connect it to the Nest app, but you can with the Home app:
Yale customers can interact with their Yale Assure Lock with Wi-Fi and Bluetooth using their voice. You can use your Google Home app to set up this feature. Your Yale Assure lock must be connected to Wi-Fi using the Wi-Fi Connect Bridge.
Just checking in to make sure that you've seen our responses. Please let me know if you have other questions or concerns as I will be locking this in 24 hours if I won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
Thanks for chiming in, Brad.
