Commissioning & Scanning
Not all my DALI devices are found during commissioning, but broadcast commands work, why?

Short answer
If broadcast commands work but not every device is found, the controller often isn't recognising certain device classes, typically input devices such as sensors (Part 303) or push-button couplers (Part 301). Check that your controller supports those device types. ProbitSite's SmartScan lists every device on the bus, type, address and firmware, without changing the configuration, so you can see exactly what is connected.
Why broadcast works but discovery doesn't
Broadcast commands reach every device at once, so lights respond even if the controller never individually discovered them. Discovery is a separate step, and that's where it fails.
The usual suspects: input devices
Specific device classes are often the ones missing, sensors (Part 303) and push-button couplers (Part 301) in particular. A controller that doesn't support these device types won't list them.
Confirm what is actually on the bus
ProbitSite's SmartScan reads every device on the line, type, address and firmware, without altering the configuration, so you can see immediately which devices exist and which your controller is missing.
