This application is a SmartThings Schema Connector that allows you to create virtual devices and import them into you SmartThings location. It also provides logging of all requests and responses between the SmartThings platform and the connector. The devices can be controlled from the SmartThings mobile app like any other device, or they can be controlled from a web page hosted by this application
The app is useful to ST Schema connector developers in showing the details of the requests and responses that a connector is expected to handle. It's also useful for general testing of the SmartThings mobile app and automations.
For general information about developing on the SmartThings IoT platform, visit the SmartThings Developer Portal.
