MiLight Ansteuerung per node-red

[andre]

Hallo,

da der Adapter für die Anbindung des MiLight Systems (RGBW LED System, limitlessled.com) an ioBroker noch im Alpha-Stadium hängt und ich (noch) nicht fit genug für die Adapterprogrammierung bin, habe ich mir als Umgehungslösung einen Flow in node-red gebastelt.

Das Ganze ist angelehnt an diesen Flow für den Zugriff via MQTT: http://flows.nodered.org/flow/b2cb3bdc5a81ac881d4b

In meiner Version dient dem Flow ein String-Objekt als Input, das ich nach Belieben aus verschiedenen Scripts und auch direkt aus iobroker.vis heraus befülle. Nach folgender Syntax:

[power].[group].[whitemode].[hue].[brightness]

Dabei können die einzelnen Segmente folgende Werte annehmen:

• power = on / off

group = 1-4

whitemode = yes / no

hue = 0-255

brightness = 1-100 

Für die Aufschlüsselung der Farbwerte hier noch eine kleine Übersicht in 16 Farben. Natürlich liegen dazwischen noch ein paar mehr:

• 0x00 = 0 = Violet

0x10 = 16 = Royal_Blue

0x20 = 32 = Baby_Blue

0x30 = 48 = Aqua

0x40 = 64 = Mint

0x50 = 80 = Seafoam_Green

0x60 = 96 = Green

0x70 = 112 = Lime_Green

0x80 = 128 = Yellow

0x90 = 144 = Yellow_Orange

0xA0 = 160 = Orange

0xB0 = 176 = Red

0xC0 = 192 = Pink

0xD0 = 208 = Fusia

0xE0 = 224 = Lilac

0xF0 = 240 = Lavendar 

Beispiel: on.1.no.176.25

Als nächste Schritte sind noch die Integration des Disco-Mode bzw. der weiteren Standardprogramme inkl. Speed up bzw. down geplant.

Für den Moment bin ich mit dem was der Flow kann aber noch zufrieden.

Hier das Bild zum Flow:

Und hier der Code zum Importieren:

Für Verbesserungsvorschläge, speziell im Code-Bereich des Flows, bin ich immer offen. :)
