When creating Timer helpers in the front end, if you change the entity_id after the fact, it is no longer possible to update the timer duration (in the helper settings dialog). The settings dialog will show the "new" duration, but the duration attribute does not change, and if you start the timer it will use the "old" duration.
What version of Home Assistant Core has the issue?
core-2024.8.2
What was the last working version of Home Assistant Core?
Received the error below when changing the entity_id of the Timer helper. Note, the new entity_id 'timer.test2' did not exist before renaming the original 'timer.test'.
Cannot migrate history for entity_id `timer.test` to `timer.test2` because the new entity_id is already in use
