Updating to 2.0 added a ton of "Dummy" switches
I'm grateful for the big rewrite, but when I tried updating I got a ton of extra tiles in Home App that I don't want. They first said "dummy" then updated to have labels after a bit.

I noticed the config syntax for buttons changed from "inputs" to "appButtons" in the documentation at some point, so I modified that but didn't notice any change.

Here's my config and a screenshot:
```

                        },

                            "name": "Apple TV"
                        },

                        }
                    ]
                }
            ],
            "platform": "webostv"
        }
```
