Edit, create and delete history records in Home Assistant from a dedicated panel in the UI.
History Editor is a custom component for Home Assistant that adds a new sidebar menu where you can view, modify and clean both state history records and statistics (short-term and long-term) for any entity. Access is restricted to administrators.
What it does
- Entity selector: pick any entity in your instance.
- Data table with state, attributes and timestamps for the last N records (up to 1000).
- Edit records: update the state value, attributes, or timestamps (
last_changed,last_updated). - Create records: add new historical entries at any point in the past.
- Delete records: remove specific entries.
- Statistics editing: view, edit and delete short-term (5-minute) and long-term (hourly) statistics records — which, in stock HA, can'”‘”‘t be modified from the UI.
- Statistics recalculation: after editing the history, force a recalculation so statistics reflect the changes. By default it recomputes short-term first, then chains long-term off it.
- Services exposed for automations and scripts:
history_editor.get_records,update_record,delete_record,create_record,recalculate_statistics.
Use cases
- Data correction: fix incorrect sensor readings or state values.
- Gap filling: add data points missing from history after a connection outage or a downed sensor.
- Testing: create sample historical data to test dashboards and automations.
- Cleanup: remove duplicates or anomalies that distort charts and aggregates.
- Migration: import historical data from other systems.
- Statistics repair: correct or remove wrong statistics data that persists beyond the normal history retention period.
