Unable to parse and format sensor.next_alarm

Tags: #<Tag:0x00007fc40d3f23d8>

Hi everyone

I’d like to translate the next alarm sensor in a markdown card but this is driving me crazy.

I got inspiration from this topic : Date in local language - #8 by 123

First I could not get the weekday(), day, month attributes from states('sensor.sm_g965f_next_alarm')) so I converted the string to timestamp with as_timestamp(states('sensor.sm_g965f_next_alarm')) and tried to get a real datetime variable by parsing it again with as_datetime().
Here’s what I tried :

  • {{ as_datetime(as_timestamp(states('sensor.sm_g965f_next_alarm'))) }} Card ends up empty (is a float)
  • {{ as_datetime(as_timestamp(states('sensor.sm_g965f_next_alarm')) | int) }} Card ends up empty (forced int)
  • {{ as_datetime(as_timestamp(states('sensor.sm_g965f_next_alarm')) | int | string) }} Displays “None”
  • {{ as_datetime(as_timestamp(states('sensor.sm_g965f_next_alarm')) | string) }} Displays “None”

What’s wrong with this variable translation ?
I just want a variable from which I can get the weekday(), day, month, hours and minutes…

Thanks for your help

strptime is what you use to format a datetime, normally.

And there are some pointers on using it in this topic The EPIC Time Conversion and Manipulation Thread!

this works fine for me (aside from the hour being in UTC)







for local time as suggested below:






The time being UTC is a pain. How can we get the “Local time” attribute ?

EDIT : {{as_local(as_datetime(states('sensor.sm_g965f_next_alarm')))}} does the trick
