Ozuno Rapix v ZenControl

This article serves to draw a comparison between the popular Lighting Control Solutions – ZenControl & Ozuno Rapix.

Zencontrol is a lighting control / building automation contender, with a focus on DALI-2 compliance, cloud integration, and flexibility in wired or wireless topologies.
Ozuno / RAPIX is a DALI-2 lighting control ecosystem designed for scalability, robust commissioning, distributed architecture, security, and a strong feature set around zones, scenes, and resilience.

Category	Zencontrol	Ozuno RAPIX
Architecture	Centralised controllers; scalable but risk of single points of failure.	Distributed zone-based design; resilient, no master controller required.
Scalability	Works well for small/medium installs; more complex at large scale.	Scales smoothly across many zones/lines; unified control across large sites.
Commissioning	Automatic addressing, cloud tools; may get complex with many controllers.	Fast tools (RAPIX Addressing/Integrator); efficient commissioning & maintenance at scale.
Resilience	Controller failure can impact zones.	Each zone runs independently; local logic keeps areas working even if network issues occur.
Security	Cloud access with TLS; adds external attack surface.	Local-first, encrypted comms between controllers; no cloud required.
Features	Scenes, circadian, daylight harvesting; strong but more controller-dependent.	Advanced Xi zones/scenes, emergency testing, rich diagnostics, extended fade times.
Integration	BACnet, MQTT, cloud APIs; depends on network/cloud uptime.	REST, BACNET, Modbus, native RAPIX; robust local integration, Control4 support, no cloud reliance.
Real-world fit	Good for smaller projects or wireless retrofits; wide installer base.	Best for enterprise/critical sites; lower lifecycle costs, higher reliability.
