OMA Smart Data Models Mapping for Lighting
Quantities to be measured
- Light on the surface of the streets. (would require a separate illuminance sensor)
- Lumens emitted by the luminaire (can be done by extending OMA data model)
- Watts consumed
- Time at which it was measured (time of completion, or start)
- Color temperature
- Weather at that time (out of scope)
- Weather forecast at that time (out of scope)
- Mains voltage and frequency. Stability.
- Active power, reactive power…
- Additional features: existence of additional elements connected to that branch.
- Location (not always provided by the device itself, but captured during installation)
Measurement conditions
- In each luminaire with Zagha connector
- At the head of the line (show how many luminaires are on it)
- Type of lighting fixtures (pedestrian zone or vehicles)
Data Models
- Outdoor Lamp Controller (OMA) Object #3416
- Electrical Monitor (OMA) Object #3418
- Street Light (Smart Data Models) Object #Streetlight

It seems there is no possibility of control over dimming, but that could be absolutely acceptable. This also explains why the vast majority of the resources are related to the Electrical Monitor (3418) and not to the Outdoor Lamp Controller (3416) The nominal lamp output in lumen at 100% dimming should be added to the OMA Data Model The color temperature is not currently present in the Smart Data Model

Cabinet controller mapping may be somehow complex. Various data models have been defined over the years, with different level of details.
