The LED Ceiling Light Tree is similar the the RGBW 24V Dimmer and the Motion Sensor Tree.
The dimming is updated at a fixed frequency of 200Hz.
| Type | Index | Name | Dir | Description |
|---|---|---|---|---|
| Digital | 0 | Motion | S←E | !=0:Motion detected |
| Analog | 0 | Brightness | S←E | Value in Lx |
| RGBW | Light RGBW | S→E | 4 bytes (RGBW) in value32 for standard devices | |
| Composite RGBW | Light RGBW | S→E | 4 bytes (RGBW) in value32 for smart devices, | |
| 0x8B | Light RGBW | S→E | B0-B7 contain the Composite RGBW, only executed if B8-B11 is !=0 and matches the magic value from the config. |
Smart Device have a fade time, which is managed by the device. The fade time is either in 1/10s (bit 14=0) or in seconds (bit 14=1). The standard devices always use the fade rate, but it can be disabled by setting bit 0 to bit 3 in B1 (for the four RGBW components). If any of the bits 0-2 are set, fading is disabled for RGB. If bit 3 is set, it is disabled for white. So, it can strangely be disabled independently.
Configuration Version 2:
| Offset | Value | Description |
|---|---|---|
| 8 | 1 | Motion Sensor Sensitivity (0-3) |
| 9 | 0…101 | Red: Loss of connection value in % (101% = Retain Last State) |
| 10 | 0…101 | Green: Loss of connection value in % (101% = Retain Last State) |
| 11 | 0…101 | Blue: Loss of connection value in % (101% = Retain Last State) |
| 12 | 0…101 | White: Loss of connection value in % (101% = Retain Last State) |
| 13 | 0…100 | Red: Fade Rate in % (0%=Jump), Bit 7: Gamma/Perception correction active |
| 14 | 0…100 | Green: Fade Rate in % (0%=Jump), Bit 7: Gamma/Perception correction active |

| 16 | 0…100 | White: Fade Rate in % (0%=Jump), Bit 7: Gamma/Perception correction active |
| 17-20 | long | magic value |
