Time interval to string

Configuration
1

Dear all,
I wonder if there is a built in function/filter I coud use to display intervals (received via MQTT as a decimal, like 1234.56) to a string, like 20 min 34.56 s.
Any pointers would be appreciated!

Well, I figured it. In case someone is interested, here it is:

{{ timedelta (seconds = states("sensor.custom_print_time_left") | int ) }}

Your solution gives a representation: if you’re happy with that, fine :slight_smile: . For more precise control of formatting, like

you might need to get a bit more involved.:

{% set s = 1234.56 %}

{{ timedelta(seconds=s) }}

{{ [(s//3600)|int ~ ' hr' if s//3600 else '',
    (s%3600//60)|int ~ ' min' if s%3600//60 else '',
    (s%60)|round(2) ~ ' s' if s%60 else '']
   |select('ne','')|join(' ') }}

Yes, thank you for your input!

I indeed just needed the representation, I wasn’t clear about it in my question.
I can see your algorithm - nothing fancy in it, I would have done the same. Just wanted to know if there is a built in way of doing it. Apparently not. :slight_smile:

Thanks again for your quick reply!!!

{{ states('sensor.custom_print_time_left') | timestamp_custom('%-M min %-S sec', false) }}

If you foresee it can exceed an hour, use %-H hr %-M min %-S sec

Need to be aware of overflow limits though:

Yepp, that IS a limit for me. The one I found timedelta works correctly for larger intervals as well.

It’s certainly more compact, particularly if you need days also!

How large are the “larger intervals”?

If it’s less than 24 hours, what I suggested will report the correct time (provided you include %H as mentioned).

It’s undeniably compact, as long as one accepts the reported data’s format because there’s no control over it.

Viktak’s first post appeared to request a desired format:

like 20 min 34.56 s

But it seems viktak dropped that requirement and has accepted whatever format is produced by timedelta … then changed his mind and reinstated the need for the original format.

Ah yes, I didn’t even notice… :slight_smile: Since it displays a 3D printer’s remaining time, I don’t really care about the decimals… With my suggestion now it reports the time remaining correctly:

Anyway, that’s why I like the forums, because even if I figure something out, there may be a better way of doing it. I never stop learning! :slight_smile:

In case anyone else is looking for a concise way of displaying seconds as hours/minutes/seconds (and suppressing hours or minutes if they’re zero):

{{ states('sensor.custom_print_time_left') | int(0)
  | timestamp_custom('%-H hr %-M min %-S sec', false)
  | regex_replace('(^0 hr| 0 min)', '') | trim }}

The pattern within timestamp_custom is easy to change if you need a different time format.

Reference: strftime

EDIT

I had a sense of déja vu while writing this post and then found that I had suggested the same technique to someone else last month:
