RoomLighting1

RoomLighting1 is a standardized approach to configuring and controlling lighting within individual rooms. It provides a coherent model for managing luminance, color temperature, and color rendering across diverse fixtures and sensors, supporting residential, commercial, and hospitality environments. The specification emphasizes modularity, scalability, and interoperability.

The core concepts of RoomLighting1 include a structured data model and declarative configuration. The model describes rooms, zones, devices, and scenes, with key fields such as room_id, zone_id, device_id, brightness, color_temperature, color_rgb, lux, occupancy, scene_id, schedule, and power state. Configurations can be authored in a declarative format and validated against a JSON schema. The approach supports multiple device types, allowing consistent control regardless of vendor.

Protocol and integration are central to RoomLighting1. It defines a device abstraction layer to harmonize different manufacturers and enables real-time control through a publish/subscribe messaging pattern, commonly using MQTT, along with a REST API for management tasks. Security considerations include token-based authentication and per-device access control lists to limit operations by user or application.

Behavior and automation features include occupancy-aware dimming, daylight harvesting, and routines aligned to sunrise, sunset, or user-defined schedules. The system supports scene management for quick lighting changes and can export energy usage data to assist with efficiency planning. It is designed to interoperate with existing smart home ecosystems via standard interfaces and adapters.

Adoption and usage vary by market and project requirements. RoomLighting1 is described as suitable for new builds and renovations seeking a consistent room-level lighting experience, with device compatibility dependent on vendor support. The standard is described as ongoing development by a consortium, with periodic updates announced to reflect evolving lighting technology.
