Trait is the common configuration for bacnet device traits. Specific implementations that pull objects together into a trait should embed this type into their specific config types. 

type OnOffConfig struct {
  Trait
  Value *ValueSource `json:"value,omitempty"`
}

func (*Trait) PollPeriodDuration

	Object   *ObjectRef  `json:"object,omitempty"`
	Property *PropertyID `json:"property,omitempty"`
	// used for converting simple units like kW -> W.
	// The value from the source will be multiplied by Scale when reading, and divided when writing.
	// For example if the trait is in watts and the device is in kW then Scale should be 1000 (aka kilo).
	Scale float64 `json:"scale,omitempty"`
}

ValueSource configures a single object property as the source of some trait value.

func (ValueSource) Lookup
