Ok Homey, What's the Current Day Number?

LyoshaDovolen

How to make Homey sent me a push (or tell me when I ask) "the number of the current day"? 
"Today is 19 of 365"

(Thanks for this nice Challenge....)

Above is a nice Try, but probably failing when Homey is not online at midnight and without notice one day behind...

I think the best solution is to let HomeyScript calculate the day on request.
To use  the calculated number  in a Flow you can use Better Logic.
(not possible with the build in Logic at the moment, see note.)

So install HomeyScript and Better Logic on your Homey.
Create a Better Logic Variable named 'DayOfYear' of type number.
Create a HomeyScript  at https://homeyscript.athom.com/
Name it for example getDayOfYear.js 
Past the script below:

// getDayOfYear.js 
// Get the Day of the Year and set it to a BetterLogic Var 
// first create a numeric variable in BetterLogic with the name below: DayOfYear 
// Relevant educational material: https://www.youtube.com/watch?v=-5wpm-gesOY
let BLVarName="DayOfYear"; 
let testDay = new Date(); 
Date.prototype.getDayOfYear = function() { 
    let thisYear = new Date(this.getFullYear(),0,1,0,0,0,0); //yyyy,jan=0, 1st day = 1, 0h,0min.,0 Sec.,0 mSec. 
    let today = new Date(this.getFullYear(), this.getMonth(), this.getDate(),0,0,0,0); //today , 0h,0min.,0 Sec.,0 mSec.
    let aday = 24*60*60*1000; // 24h x Min x Sec x mSec.  
    return  Math.round(1+(today - thisYear)/aday); // Varies ~0.04 on non-DST vs DST days
};
let dayOfYear = testDay.getDayOfYear();
console.log(dayOfYear);

// for HomeyScript Tags/tokens 
await setTagValue(BLVarName, {type: "number", title: BLVarName}, dayOfYear ); 
// or for for Better Logic, just use What you want!  
let BLApp = await Homey.apps.getApp({id:"net.i-dev.betterlogic" }); 
let result = await BLApp.apiPut("/" + BLVarName + "/" + dayOfYear ); 
return true;

Create a Flow to test:


By using it as a Dummy condition (...and...) it will calculate "just is time" the actual day number once again and set the Better Logic Variable for you to use in the Action (...Then)

Test it: 


(Although I like BetterLogic, I tried without but setting (Homey) Tags from  HomeyScript is not possible  at the moment. See GH Issue https://github.com/athombv/homey/issues/2171)

Edit: Math.round for result  Varies ~ 0.04 on non-DST vs DST days
Edit 2:  updated to use HomeyScript Tags, Better Logic is not necessary anymore.

updated to use HomeyScript Tags (Possible from App version 1.0.4),
Better Logic is not necessary anymore.
