Hi,  
I need to remove a part of a variable.  
My Bosch washing machine reports remaining time as «160:0».  
I need a flow for removing the «:0»-part and setting this as a number variable.

Any tips? 🙂

This converts the time tag (string), say it is 11:07 AM, into the numeric value 11

I’m sure you can do the same with the Bosch variable/tag  
`{{ 0+("<RemainingTimeTag>".split(":")[1]) }}`

You can play with the [1] if the wrong part is omitted before or after the `":"` sign, by using [2] etc.

Thanks @Peter_Koolen! 😀

Next question @Peter_Kawa, how can I easily convert a numeric value (160) into a text variable in the format “1 hour and 40 minutes”?

Is it a quiz? 😜  
Oh i’m not mister Koolen 😊 😉

Use the following THEN card  
 ![Screenshot from 2023-04-26 21-22-07](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/1/212dfe8a694508a7b25e0d09161378b3c68d78f1.png)

Replace the example code at the [Code] part with:

```auto
//Convert number (as argument) to HH:mm

function toHoursAndMinutes(totalMinutes) {
  const hours = Math.floor(totalMinutes / 60);
  const minutes = totalMinutes % 60;

  return `${hours} hour and${minutes > 0 ? ` ${Math.round(minutes)} minutes` : ''}`;
}

// To check the argument value:
console.log("Argument value:", args[0]);

return toHoursAndMinutes(args[0]);

```

Then you’ll get something similar like this, use a numeric variable or tag of your choice (I used just a numeric variable) as argument (=input), connect both cards and use local [Result] string tag in further processing:

The minutes get rounded, to avoid f.i. 45.766666666666 as the minutes number

Or you can use the [Better Logic Library](https://homey.app/a/net.i-dev.betterlogic/) expressioncard:  
Place this in the card: `time('H" hours and "m" minutes"', 160*60*1000)` and replace the 160 with the token/tag.

Endes up using this, @Arie_J_Godschalk. 😀

At what time (date) in the day you mean?

Here, here you just add your token and multiply it to be milliseconds.  
Then you add the current `Date.now()`, which is the current time in milliseconds.  
The result you put as second parameter to the `date()` function.  
For other formats than `datetime`, like just `time`, see the Better Logic Library App Settings, there are a lot of options and you can create your own custom pre-defined format:

`date('datetime', Date.now() + 160*60*1000)`

I’ve been struggling with the following for a while now.

The ANWB route planner app creates travel times as follows: 00:30.

However, if I have this spoken through the Google Speaker, it makes it half past twelve at night.

I would like to remove 00: somehow.

How can I do this.

Not BLL, but it works:  
The travel time is available from a tag I presume.

`{{ 0+("[ANWB_tag]".split(":")[2]) }}`

With your example of 00:30, it would be this calculation:  
`{{ 0+("00:30".split(":")[2]) }}`

I tested with the [Time] tag:

You see it only uses the minutes part of the time:

Your the best. This works!!!
