Template Sensor for Alarm System Activity with filters

Greetings,

I’m trying to make a card that shows the arm/disarm activity by PIN for our alarm (Simplisafe). Here’s what I have figured out so far:

I started with the state of the alarm system and figured out how to select an attribute from that state.

Alarm Control Panel Entity Attributes
code_format: number
changed_by: null
code_arm_required: true
last_event_info: System Disarmed by Master PIN
last_event_sensor_name: Office
last_event_sensor_type: keypad
last_event_timestamp: 1713104017
system_id: 1250416
alarm_duration: 480
battery_backup_power_level: 5567
entry_delay_away: 40
entry_delay_home: 60
exit_delay_away: 45
exit_delay_home: 40
gsm_strength: -71
light: false
rf_jamming: false
wall_power_level: 6363
wifi_strength: -58
alarm_volume: high
chime_volume: high
voice_prompt_volume: high
friendly_name: Alarm control panel
supported_features: 3

Using a template sensor helper I started to record those changes to the last_event_info attribute.

‘sensor.alarm_history’

{{ state_attr('alarm_control_panel.alarm_control_panel', 'last_event_info') }}

Then I made a card using the custom logbook card that shows my new sensor’s history.

my card yaml
type: custom:logbook-card
entity: sensor.alarm_history
show:
  state: true
  duration: false
  start_date: true
  end_date: false
  icon: false
  separator: false
  entity_name: true
title: Alarm History
max_items: 10
collapse: 5
custom_logs: false

What I’d like to do is filter out the Exit Delay Countdown Triggered for Home Mode by Keypad records from the sensor.

In my head something like system disarmed * and system armed * could be added to the template sensor configuration somewhere so that only attributes starting with those templates get recorded. Is that possible?
