Node-Red mit Alexa - Dimmer

rewenode

Ich kenne mich da leider nicht gut aus.

Aber sollte sowas nicht hilfreich sein?

https://www.npmjs.com/package/node-red- … or-convert

` > This node converts between different color representations, it can convert between the following systems.

RGB - Red, Green, Blue

HSL - Hue, Saturation, Level

HSV - Hue, Saturation, Value (brightnes)

CSS - CSS color names `

dondon4002

Ja den habe ich ausprobiert aber irgendwie klappt es damit nicht so richtig. vielleicht mache ich es auch falsch.. Am Ende wäre es aber der richtige Converter dafür. HSV Array-> RGB als Array

Man müsste dann aber schauen das man vorher Saturation und Brightness noch *100 nimmt..

Gut ist immer, wenn man ein Beispiel zeigen kann, wie es sein soll.

So nach dem Motto:

Für gelb müssen folgende states folgende Werte bekommen…

~~@dondon4002:~~

Man müsste dann aber schauen das man vorher Saturation und Brightness noch *100 nimmt.. `

Versuch doch mal die Werte per Hand bei den States zu setzen und schau, ob die Hue reagiert wie sie soll. Wenn das geht, sollte man das auch per flow hinbekommen;-)

dondon4002

Also irgendwas passt nicht :-(

if ((msg['command']) == 'SetColorRequest') {
  msg['payload']['hsv'] = [(msg['payload']['hue']), (msg['payload']['saturation']) * 100, (msg['payload']['brightness']) * 100];
  return msg;
} else {
}

Ausgabe Alexa und Blocky:

{"hue":0,"saturation":1,"brightness":1,"hsv":[0,100,100]}

Ausgabe Converter (HSV to RGB)

[3,3,3]

rewenode

Also wenn ich dich recht verstehe, soll zb. die Alexa Ausgabe so konvertiert werden. oder wie?

sollte rot sein.

{"hue":0,"saturation":1,"brightness":1,"hsv":[0,100,100]}

so aussehen:

ist immer noch rot, nur rgb

{"hue":0,"saturation":1,"brightness":1,"rgb":[255,0,0]}

oder verstehe ich das falsch?

dondon4002

Alexa wirft bei "Alexa Schalte Test auf ROT" dies aus:

"hue":0,"saturation":1,"brightness":1

dies schiebe ich in den Blocky und mache ein Array daraus damit dies kommt:

"hsv":[0,100,100]

Der Converter macht aber nun ein RGB Array und zwar so:

[3,3,3]

Es müsste aber für den HUE Adapter so kommen:

RGB [255,0,0]

rewenode

Ich hoffe, ich habe richtig kapiert.

Das sollte auch ohne Blockly problemlos gehen:

hier der flow:

 ![3999_bild_1.png](/assets/uploads/files/3999_bild_1.png) 

Am Eingang bekommt das Teil ein Oblect````
{"hue":0,"saturation":1,"brightness":1}

Am Ausgang hast du ein Array````
[r,g,b]

Wenn das lieber ein Object sein soll, der Form:````
{"rgb": [r,g,b]}
````ist eine minimale Änderung nötig.

dondon4002

Perfekt :D dann hab ich nur den Converter falsch benutzt :D :D danach noch nen Change to msg.payload.rgb und Alexa schaltet das ganze :-) Danke dir

rewenode

~~@dondon4002:~~

… Change to msg.payload.rgb `

Exakt so :D falls nötig

dondon4002

Für alle die dann noch Bedarf daran haben :-)

Ich mache es am Ende doch per Blockly denn es kommen ja noch Abfragen wie TurnOnRequest, TunOffRequest und was Alexa noch alles so bietet.

Nur zu, im Prinzip weist du ja jetzt wie es geht ;-)

Hi,

ich habe ein Problem mit der Range des Dimmers. Der Dimmer möchte 0-100 und Alexa 0-1.

Hier ist mein "Flow" der HomeKit Dimmer kommt da anschl. auch noch dran….

~~@Blackeye:~~

Was heisst Alexa 0-1 ? Alexa liefert dir einen Wert von 0-1 und der soll nach 0-100 umgesetzt werden?

Blackeye

Hi,

genau so…..

rewenode

~~@Blackeye:~~

Hi,

genau so….. `

Na wie wäre es, wenn du den von Alexa kommenden Wert 0-1 einfach mit 100 multiplizierst ?

Blackeye

Hi,

ja auf die Idee bin ich auch gekommen, finde nur nirgendwo wie ich das mache.

Gruß

Lars

Sollte so gehen:

Klar geht das. Der Sinn will sich mir aber nicht erschließen, wo er den change doch schon drin hat;-)
