I created a new Thing Template with 2 propeties Status and Level.
What is the best methods to create new Services like :
1) PutProperty store Status and Level into Thingworx
2) GetLastProperty get last value of Status and Level from Thingworx
3) GetHistoryProperty get value of Status and Level by timeline from Thingworx
Are you trying to create custom services that will call services to set the properties and return historical property values?
