ProbitSite
The DALI Multimeter
The standard diagnostic tool for DALI installations.
ProbitSite is the professional diagnostic and commissioning tool for DALI installations. It helps electricians, commissioning engineers and service technicians find electrical and communication faults in minutes without changing the existing installation.
"It is a fantastic tool and really helped us identify the issues we were having. I'm looking forward to using mine in the future!"

Fully DALI-2 certified test deviceWhat ProbitSite Does
Connect ProbitSite to any DALI line and diagnose the typical faults you meet in the field: communication errors, wrong or duplicate addresses, non DALI-2 certified ballasts, wiring problems and unstable signal levels. In new and existing installations alike.
SmartScan reads every DALI device on the bus without touching the existing configuration.
Intuitive signal quality indicator with bit-timing analysis of the physical DALI layer.
DALI data logger records every telegram from the moment it powers on (30,000+ bus reads).
Spots devices that are not DALI-2 certified by checking them against the DiiA database.
Detects wrong or duplicate addresses, wiring errors, bus short circuits and unresponsive devices.
Stand-alone Configuration: Set, change, and delete DALI short addresses directly from the handheld device (Expert Mode).
Integrated DALI bus power supply. Works on any installation, even before a controller is present.
The only DALI-2 certified test device on the market. View certification on dali-alliance.org
Why analysing DALI problems on the physical and electrical level is the only way to get comprehensive answers
Standard USB DALI dongles only see the logical protocol. ProbitSite analyses the physical layer: signal quality in percent and the precise timing of backframes. That is how you find hardware defects and wiring problems other tools simply ignore.
Typical USB DALI Dongle
Logical layer only
- Blind to electrical signal quality. Cannot tell a clean bus from a marginal one.
- No backframe timing analysis. Slow or out-of-spec replies stay invisible.
- Not DALI-2 certified. No accredited test report you can hand over.

Physical and logical layer
- Intuitive signal quality indicator with precise backframe timing.
- Finds hardware defects, wiring faults and overloaded bus lines other tools ignore.
- The only DALI-2 certified test device on the market. Hand over an accredited report.
Address on site. Analyse at your desk.
Manage DALI short addresses directly on the handheld with Expert Mode, then import your scans into the Windows App to review, organise and document them.
Expert Mode on the device
From Firmware V1.5: set, change and delete DALI short addresses directly on the handheld, no laptop required. Expert Mode is unlocked once from the Windows App and signalled by a cog icon on screen so live installations are protected from accidental changes.
- Assign a short address to an unaddressed device
- Change or delete an existing short address
- Resolve duplicate address conflicts on site
Windows App at your desk
Import DALI scans via USB, review them, organise scans by project and print professional reports. The desktop companion turns raw scan data into acceptance-ready documentation.
- Import and analyse DALI scans over USB
- Organise scans by project
- Print professional reports
