In the deviceWISE Cloud, properties are numeric values representing a value at a specified timestamp. Typically this would be a sensor reading such as voltage, humidity, speed, and so on. Properties have a history and is aggregated over time periods for use in graphs or tables using the property.history and property.aggregate TR50 commands.  Properties are defined in a thing definition. Things inherit their properties from their thing definition. The properties can be integers or floats, signed or unsigned and may be negative or positive.

Below are some property examples in JSON format:
