Welcome! I came from Staples Connect myself which is why I decided to write this deviceType. Here is a great FAQ about custom deviceTypes and SmartApps: FAQ: An Overview of Using Custom Code in SmartThings
Using this info you can add the devicetype using the smartthings IDE (graph.api.smartthings.com/ide). ST has a bit of a steep learning curve but it’s a whole lot more capable than staples connect was.
