Colorpicker-Wert als Hex z.B. #FF00FF

Hallo "nelzon".
Hier mal das Script das ich auf dem ESP8266 als Melder verwende.
Dieses habe ich aus verschiedenen Beispielen zusammengestellt und angepasst.
Welche Librarys du benötigst kannst du dem Script entnehmen.
Ansonsten ist das Script gut dokumentiert und anzupassende Stellen habe ich markiert.
Beim ersten Start erzeugt dieses Script die erforderlichen Topics im ioBroker selbst, vorausgesetzt du hast auch im ioBroker den MQTT-Adapter als Server installiert und die IP-Adressen und Zugangsdaten im Script entsprechend angepasst.

Zur Umwandlung kann auch das NPM-Modul https://www.npmjs.com/package/rgb-hex verwendet werden, das als "Zusätzliches NPM-Modul" in der JS-Konfiguration anzugeben wäre.

Danke schon mal im voraus. Werde mich die Tage mal damit beschäftigen.

Hallo,
also der Tip ist schon toll, aber wie kann man dieses Modul funktionsfähig einbinden/ Installieren??
****OK, hat sich erledigt:)!
Für die, die es auch nicht wissen:
1. npm install –save rgb-hex
2. in der Konfiguration des javascript-Adapter unter "Zusätzliches NPM-Modul" rgb-hex eintragen;).****
-
Wie geschrieben: In der Konfiguration der Javascript-Instanz unter "Zusätzliche NPM-Module" rgb-hex eintragen. Dann wird es automatisch installiert.
Im Skript steht dann mit
const rgbHex = require('rgb-hex');die Funktion rgbHex(R,G,B) zur Verfügung.

habe da mal ne Frage..
ich kann an meinen Wemos via HTTP Befehle senden um mein WS2812-Strip zu steuern
z.B. http://192.168.xxx.xx/control?cmd=nfx+all+ff0022
in Blockly arbeite ich mit der URL um den Strip zu steuern (in Verbindung mit Taster in Homematic)
wie kann ich jetzt in VIS eine Farbsteuerung (Änderung des Hex-code in der URL) vornehmen? Jemand ne Idee? Am besten mit einem Farbkreis oder vergleichbarem.
Blockly ok, aber Javascript ist nicht mein Gebiet.

Hallo,
ich basel heute schon den ganzen Tag an einem kleinen Problem, und komme nicht recht weiter:(.
Im Zuge meines kleinen RGB-WS8212-MQTT-Projekts benötige ich einen Datenpunkt,
der die RGB Farbwerte des Colorpicker-Widgets in der in HTML üblichen Hexadezimalen Darstellung, also z.B. #FF00FF beinhaltet.
Leider erzeugt der Colorpicker ja "nur" 3 separate Datenpunkte mit den einzelnen Farben R, G, B, und das noch als Zahl mit Nachkommastellen.
Also z.B. aus 16.000, 104.000, 30.000 aus dem Colorpicker soll #10681E werden
Ich habe nun schon diverse Umwandlungen versucht, komme aber zu keinem Ergebnis.
Kann mir da jemand helfen?? `
Wo machst du diese Umwandlung?Wenn das ioBroker.javascript Adapter währe, dann wird so was gehen:
createState('ledRGB', 0); createState('ledR', 0); createState('ledG', 0); createState('ledB', 0, function () { on('javascript.0.ledR', calculateColor); on('javascript.0.ledG', calculateColor); on('javascript.0.ledB', calculateColor); }); function toHex(number) { if (number < 0) number = 0xFFFFFFFF + number + 1; var n = number.toString(16).toUpperCase(); if (n.length == 1) { n = '0' + n; } return n; } function calculateColor() { var R = Math.round(parseFloat(getState('javascript.0.ledR').val) || 0); var G = Math.round(parseFloat(getState('javascript.0.ledG').val) || 0); var B = Math.round(parseFloat(getState('javascript.0.ledB').val) || 0); setState('javascript.0.ledRGB', '#' + toHex(R) + toHex(G) + toHex(B)); } ```` `Hey. Das Script funktioniert super. Ich nutze allerdings den yahka adapter, der keine RGB-Daten sondern eine Zahl zwischen 0 und 65535 zurück gibt. es scheint ein Spezielles Hue-Format zu sein. ist dir dieses Format bekannt und wäre es möglich das Script dafür umzuwandeln?
vielen Dank und schönen Gruß

Gibt es bezüglich der Problematik mit dem Yahka und dem hue-wert eine Lösung ?

habe da mal ne Frage..
ich kann an meinen Wemos via HTTP Befehle senden um mein WS2812-Strip zu steuern
z.B. http://192.168.xxx.xx/control?cmd=nfx+all+ff0022
in Blockly arbeite ich mit der URL um den Strip zu steuern (in Verbindung mit Taster in Homematic)
wie kann ich jetzt in VIS eine Farbsteuerung (Änderung des Hex-code in der URL) vornehmen? Jemand ne Idee? Am besten mit einem Farbkreis oder vergleichbarem.
Blockly ok, aber Javascript ist nicht mein Gebiet. `
hast du eine lösung gefunden ? hab ein ähnliches Problem
