When you commission a Lutron Connect bridge for the first time in a RadioRA 2 system, the next step is to discover the bridge from your Lutron Connect app. When you open the app, it prompts you to either Add a Home or Log In into Existing account. If you are doing this for the first time, chances are you must Add a Home and create new credentials (email/psswd). The trick is that you cannot use the same email address you use for the Caseta system. If you use the same address, the Connect Bridge will time out during registration. Hope this helps!
