How to split this variable message?

Configuration
1

I was using this but the message varies…

value_template: '{{ states("sensor.front_door_lock_logging").split(" Today ")[0] }}'

The current message is:

'Locked Manually  on 2021-02-24 at 2:27:08 AM User Code=0'

but it can be:

'Unlocked Manually  Today at 8:39:00 AM User Code=0'

or:

'Locked using Z-Wave  Today at 8:40:59 AM User Code=0'

Here are all of the components:

      frontdoor_lock_log_message:
        friendly_name: "Message"
        value_template: '{{ states("sensor.front_door_lock_logging").split(" Today ")[0] }}'

      frontdoor_lock_log_user:
        friendly_name: "User"
        value_template: '{{ states("sensor.front_door_lock_logging").split("User=")[1] }}'

      frontdoor_lock_log_date:
        friendly_name: "Date"
        value_template: '{{ as_timestamp(states.sensor.front_door_lock_logging.attributes["last_change"]) | timestamp_custom("%A %b %d") }}'
        
      frontdoor_lock_log_time:
        friendly_name: "Time"
        value_template: '{{ as_timestamp(states.sensor.front_door_lock_logging.attributes["last_change"]) | timestamp_custom("%H:%M:%S") }}'

Regular Expressions FTW!

      frontdoor_lock_log_message:
        friendly_name: "Message"
        value_template: '{{ states("sensor.front_door_lock_logging") | regex_replace("\s{2,}.*$","") }}'

Removes everything after and including two (or more) spaces.

      frontdoor_lock_log_user:
        friendly_name: "User"
        value_template: '{{ states("sensor.front_door_lock_logging") | regex_replace("^.*Code=","") }}'

Removes everything and including “Code=”, effectively leaving just the code inplace.

Regex is a really good for this.

{% set str = 'Unlocked Manually  Today at 8:39:00 AM User Code=0' %}

{{str}}

message: {{ str | regex_findall_index('(.*)\s\s') }}
User {{ str | regex_findall_index('User Code=(.*)') }}
Date {{ str | regex_findall_index('Today|\d{4}-\d{2}-\d{2}') }}
Time {{ str | regex_findall_index('at\s(.*)\sUser') }}

It works on all the test strings you presented.

Just replace str with the entity

Thank you @m0wlheld and @Hellis81! You both targeted the double space which I missed!. Sometimes you can’t see the forest for the trees! I should be able to use this:

value_template: '{{ states("sensor.front_door_lock_logging").split("  ")[0] }}'

I will keep read up on regex and keep in mind for future reference…
