State agnostic simulated switch?

I tried this but when I tried to add a switch I get an ‘An Unexpected error has occurred’ message when I click done. Do I need to turn on OAuth or something? Here’s the log:

physicalgraph.app.exception.UnknownDeviceTypeException:

Device type ‘Stateless On-Off Button Tile’ in namespace ‘gouldner’ not
found. @ line 50

The Stateless On/Off Button Tile does exist and is published.
