Commissions DALI and DALI-2 (IEC 62386) lighting buses: short-address assignment (0-63), 24-bit binary search collision resolution, groups, and DT8 color control. Trigger phrases: commission dali, dali short address, dali collision resolution, dali bus addressing, dali-2 setup.

When to use

• Bringing up, commissioning, or expanding DALI or DALI-2 lighting installations (KNX/DALI gateways, Tridonic, Philips Dynalite, Helvar, Osram, Lunatone).
• The user asks: "How do I commission this DALI bus?", "Fix duplicate DALI short addresses", "Assign DALI addresses without erasing existing fixtures", or "Program DALI groups and DT8 tunable white".
• Resolving address clash loops where multiple ballasts respond simultaneously to broadcast queries.
• Designing or scheduling DALI-2 Part 202 emergency lighting duration and function tests across staggered floor circuits.
• Commissioning DMX512/RDM stage lighting, 0–10V analog dimming, or proprietary wireless RF networks (Zigbee, Bluetooth Mesh, Casambi).
• Diagnosing dead ballasts or physical wiring faults before basic DALI bus voltage (12V–20.5V DC) and current limits (<= 250mA) are confirmed.
• Programming building-wide KNX logic (this skill covers the DALI protocol domain strictly).

When not to use

• DALI command support, timing, gear limits, and DT8 behavior vary by control gear, device type, and IEC 62386 edition. Confirm commands against the exact gear and gateway manuals before transmission.
• Commissioning can disrupt occupied lighting and emergency systems. Coordinate an approved outage and have a qualified lighting professional verify any live bus operation; never treat these examples as a substitute for site procedures.
• Pseudo-code is illustrative and is not a tested gateway driver. Verify address mapping and every fixture physically before saving configuration.
