Modifying the 'next alarm' sensor data before sending it to a text helper

Hi,

For a bedtime routine automation i need to take the value of my phones ‘next alarm’ sensor to be modified and stored into a text helper.

Originally the sensor value looks like this: Fri Jun 10 06:45:00 GMT+02:00 2022
I would like to modify it to look like this: Friday 06:45

I’ve never done any templating and hope someone can help me with this

Doesn’t your next alarm sensor give you an attribute with the timestamp in UNIX?

It show’s the following attibutes.

You can use:

{{ (state_attr('sensor.note_20_next_alarm', 'Time in Milliseconds')/1000) | timestamp_custom("%A %H:%M")}}

Or you could have a look at:
