Home Assistant: Logbook search or filtering?
Home Assistant offers comprehensive functions for monitoring and logging status changes. The integrated Dashboard: Logbook provides detailed information on all changes, but can only be filtered to specific entities and a specific time period, but not whether a specific value is included:
Search function: Not available
The activity card is expected to get a status filter with version 2025.12, see: ✓ Adding a status filter to the activities card.
HACS Logbook Card
The HACS Integration Logbook-Card is being traded as a solution:
Prerequisite: Home Assistant integrations
The "hidden_state" property can filter one or more events based on a search text; it is also possible to use wildcards:
type: custom:logbook-card
entity: sensor.openwrt_newdhcpleases
hidden_state:
- "state2hide"
- "*2*"hidden_state: "*2*" would remove all values containing 2 from the list.

Conclusion
The HACS-Card loogbook-card can be used to filter certain history data, but I can't quite understand why the logbook integrated in Home Assistant hasn't had a search or filter function since the beginning?
