It has 63 installs sharing analytics, works locally and was last updated October 1, 2026. Last Changed Keeper restores the real last changed time of entities after a Home Assistant restart. Normally that value resets to the restart time, so the integration reads the true start of each entity's current value from the recorder and writes it back directly on the entity, without extra sensors. It only backdates entities whose value did not change across the restart, and it leaves entities alone once they are no longer fresh. Selection can cover all entities, or specific domains, labels, areas and individual entities, with an exclusion list, and it can also restore last updated and the last triggered time of automations and scripts. It adds a restore now button, a sensor for restored entities, and a verify action that compares live values with stored ones without changing anything. It runs locally and is set up in the UI.

Returns any mismatches found - useful for diagnosing "the value looks wrong" reports. ## Troubleshooting - **Diagnostics**: Downloads a diagnostics file to attach to a bug report. - **Repair notices**: Notices it can show in Settings, Repairs: Last Changed Keeper: incompatible HA version ## From the README > Keeps the real "last changed" time of your entities after a Home Assistant restart. Normally last\_changed jumps to the restart time ("2 seconds ago" instead of "17 minutes ago"); this integration restores the true time from the recorder — directly on the entity, no extra sensors.
