To ensure reliable operation, the app automatically analyses the complexity of scene configurations as they are being created. To prevent situations that may adversely affect network performance, warnings will be presented should a scene become overly complicated.
A “complex” scene is one that contains many luminaires set to many different dimming levels, colours, &/or colour temperatures. It is not possible to define exactly, since the quantity of differing dimming levels, colour & colour temperatures used have varying impacts on system performance depending on the chosen combination.
There are two warning levels:
1) Scene complexity is near the limit (Yellow warning triangle at the top of the screen).
2) Scene complexity limit has been reached or exceeded (Red triangle at the top of the screen, plus an additional pop-up message). Such a scene cannot be saved or used!
Scene complexity data limits explanation
A Casambi scene has a maximum data size of 510 bytes.
Every unique setting within a scene (e.g. the combination of dimmed level, colour temperature, colour etc) consumes 3+N bytes of data (3 bytes is fixed & N varies depending on the luminaire capabilities).
The maximum number of unique variations in a scene is 510/(3+N). A scene with different luminaires, or same luminaires with different settings (i.e. different dim levels), will consume 3+N bytes for every variation.
Examples of N for different luminaire capabilities
| Dimmable only | N=1 |
| Dimmable + Tuneable White | N=3 |
| Dimmable + RGB | N=4 |
| 8-channel dimmable | N=8 |
| Complex luminaire (e.g. pan, tilt, zoom etc) | N=number of unique functions |
Examples of maximum unique variations per scene:
| Dimmable only (3+1 bytes) | 127 (510/4) |
| Dimmable + Tuneable White (3+3 bytes) | 85 (510/6) |
| Dimmable + RGB (3+5 bytes) | 63 (510/8) |
| 8-channel dimmable (3+8 bytes) | 46 (510/11) |
More examples:
• A scene with identical luminaires, all with identical settings will use 3+N bytes in total.
• A scene with only dimmable luminaires can have 127 unique luminaire dimming levels.
• A scene with 10 dimmable luminaires (all set to the same dimmed levels) & 10 Dimmable + RGB luminaires (all set to the same dimmed level & colour), will use 12 (4+8) bytes in total.
• A scene with 10 dimmable luminaires (all set to different dimmed levels) & 10 Dimmable + RGB luminaires (all set to different dimmed levels & colours), will use 120 ((4*10)+(8*10)) bytes in total.
