A node for controlling WLED devices from NodeRed. The node supports a single segment, and can control the effect (including speed and intensity), palette, color, and brightness level of the segment.
Additionally a delay can be specified. This causes the LEDs to run the selected effect until the delay expires, then switch to a solid on (or off) state. This is handy for running an effect briefly before turning on to a solid color (or turning off).
The various parameters for the LEDs can also be provided by the incoming payload via a JSON object. Supported JSON properties are:
| Property | Description | Type | Example |
|---|---|---|---|
brightness |
The brightness for the LEDs. Supported range is 1 to 255. | number | 128 |
color1 |
An RGB array of the first effect color. | number[] | [255, 128, 4] |
color2 |
An RGB array of the second effect color. | number[] | [128, 255, 4] |
color3 |
An RGB array of the third effect color. | number[] | [4, 128, 128] |
effect |
The number for the effect. See GitHub for the valid numbers. | number | 5 |
effectIntensity |
The intensity of the effect. Supported range is 0 to 255. | number | 128 |
effectSpeed |
The speed of the effect. Supported range is 0 to 255. | number | 128 |
delay |
Number of seconds to wait before switching to the Solid effect. | number | 5 |
palette |
The number for the palette. | number | 5 |
preset |
The preset to display. If specified all other properties are ignored. Set to 0 to disable sending a preset to the WLED controller. |
number | 16 |
seg |
The segment or array of segments to configure. See the WLED JSON API documentation for information on the supported properties. | object | |
state |
The state to set the LEDs to. Supported values are on, off, and toggle. This will also be used in the segment section to turn on/off a segment. Segments states are not saved only the global state. |
string | toggle |
segmentId |
The segment Id to control, default is 0 (main segment) | number | 0 |
debug |
On will cause the JSON payload sent to WLED to be output to the debug console via node.warn()
|
string | no |
segRange |
Number of segments to set to the current conditions. i.e. 3, would set segment 0, 1, 2. (0 to segRange) |
number |
