UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

[Mr_Sans]

Hallo Zusammen

Ich habe mich in den letzten Tag ein wenig mit dem automatischen switch von Light-Mode zu Dark-Mode beschäftigt.
Würde gerne mein Stand mit euch Teilen und freue mich über Anregungen oder Verbesserungen.

Ich nutze vorwiegend @Scrounger Material Design Widgets.

Als erstes habe ich mir im JS-Adapter ein Script erstellt, welches anhand der Tageszeit ein Datenpunkt befüllt

// imports NPM Module
const moment = require("moment");
moment.locale("de");

// Skript Einstellungen *************************************************************************************************************************************************
let debug = true;                                                                                           // Debug Meldungen anzeigen
let strukturChannel = '0_userdata.0.vis.Scripts.Control';                                                      // Übergeordnete Id, wo die Datenpunkte angelegt werden sollen
 
let idColorDatenpunkt = `${strukturChannel}.datapoint_color`    

createControlDatapoints();

schedule({hour: 08, minute: 00}, lightmode );
schedule({hour: 19, minute: 30}, darkmode ); 

 function darkmode() {
   setState(idColorDatenpunkt, 'darkmode');
 }
 
 function lightmode() {
   setState(idColorDatenpunkt, 'lightmode');
 }



function createControlDatapoints() {
    if (!existsState(idColorDatenpunkt)) {
        if (debug) console.debug(`[createControlDatapoints]: create datapoint '${idColorDatenpunkt}'`);
        mySetState(idColorDatenpunkt, 'lightmode', 'string', `Light or Dark Mode`);
    }
}

function mySetState(id, val, type, name) {
    if (existsState(id)) {
        if (debug) console.debug(`[mySetState]: history colore data stored to '${id}'`);
        setState(id, val, true);
    } else {
        if (debug) console.debug(`[mySetState]: create datapoint '${id}'`);
        createUserStates(false, [
            id, {
                'name': name,
                'type': type,
                'read': true,
                'write': true
            }
        ], function () {
            setState(id, val, true);
        });
    }
}

                            }
                        });
                    }, DELAY + (20 * counter));
                }
            });
        });
    }
}

Dieser Datenpunkt wird verwendet um z.B den Zustand auch den Charts übergeben zu können, da diese nicht vollständig übers CSS angepasst werden können. Im Editor hab ich folgendes hinterlegt:

{wert:0_userdata.0.vis.Scripts.Control.datapoint_color;(wert =="lightmode") ? "#505050" : (wert =="darkmode") ? "#ffffff" : "#ffffff"}

Da leider der JS-Adapter nicht direkt auf das CSS zugreifen kann, nutze ich das Register Skript im Editor für einen zusätzlichen Workaround:

vis.registerOnChange(status_callback);
 
vis.subscribing.IDs.push("0_userdata.0.vis.Scripts.Control.datapoint_color");

function status_callback(arg, id, val, ack)
{
    if (val=="lightmode")
    	document.documentElement.setAttribute('data-theme', 'light');
			localStorage.setItem('theme', 'light');
    if (val=="darkmode") 
    	document.documentElement.setAttribute('data-theme', 'dark');
			localStorage.setItem('theme', 'dark');
    
    console.log('Status', 'Id:' + id+', Val:'+val);
}

let objID = '0_userdata.0.vis.Scripts.Control.datapoint_color';
servConn.getStates(objID, (error, states) => {
    let stateValue = states[objID].val;
        if (stateValue=="lightmode")
    	document.documentElement.setAttribute('data-theme', 'light');
			localStorage.setItem('theme', 'light');
    if (stateValue=="darkmode") 
    	document.documentElement.setAttribute('data-theme', 'dark');
			localStorage.setItem('theme', 'dark');
    
    console.log('Status', 'Id:' + id+', Val:'+val);
});

Das CSS sieht wie folgt aus:

/* Design-time light-Theme */
:root[data-theme="light"] {
  --main-background: #ffffff;
  --content-background: #f5f5f5;
  --content-background-hover: #505050;
  --design-font-color: #505050;
  --design-font-color-hover: #ffffff;
  --design-fontsize : 0.9em;
  --filter-svg:;
  --filter-svg-hover: brightness(0) invert(1);
  --border-color: #e0e0e0; 
} 
/* Design-time dark-Theme */
:root[data-theme="dark"] {
  --main-background: #000000;
  --content-background: #505050;
  --content-background-hover: #808080;
  --design-font-color: #ffffff;
  --design-font-color-hover: #505050;
  --design-fontsize : 0.9em;
  --filter-svg: brightness(0) invert(1);
  --filter-svg-hover: ;
  --border-color: #404040; 
}

Ich habe den grössten Teil Design-Teil im CSS und mache nur das nötigste im Editor (dies vorallem, da ich aktuell auf Rund 180 Seiten bin und bei kleinen Änderungen nicht alle Seiten öffnen möchte für Anpassungen.
Bei mir Funktioniert dies wunderbar.

Hier mal noch ein grosses Lob an @Scrounger und seine Widgets --> Hammer!!

Viel spass beim ausprobieren und für allfällige Feedbacks...

coole Geschichte! Der Mode wird aktuell gemäss einer fixen Zeit aus dem schedule erstellt. Eine Idee wäre auch, den Status des "dark modes" direkt aus dem Browser auszulesen, was meinst du?
