2. create a extension with this file.(https://www.youtube.com/watch?v=ZlxFok1Y_HU)
3. Import that extension in Thingworx.
4. After importing that extension a Thingtemplate will be created in the thingworx.
5. Put all the details like username password,Connection Url and driver name.
6. create a service for fetching the data.
