Device replacement without losing history

[Fabrizio1]

Hello everyone.
I have Home Assistant Core with the default SQLite DB ed zigbee2mqtt on Docker.
A Zigbee MMQ temperature sensor is broken and I would like to replace it.
I would like to “hook” the history of the previous sensor to the new one, how do I do it?

Just rename the new entity to exactly the same name as the old entity.

Thanks, are these the steps i need to take?

1. Delete device
   Shouldn’t I delete the story too?
   

   

2. Rename the new entity to exactly the same name as the old entity

I would delete the “temperature entity” and any other entity you want history for.
Then rename the new entities.
Finally delete the entire old device.

Yes, just add the new entity. Change the entity_id of the old entity to a holder name, change the entity_id of the new entity to what the old entity’s entity_id used to be. EDIT: The new process is: Delete old entity Rename new entity to old entity_id New entity will inherit old entities history Do not under any circumstances rename the old entity before you delete it, this will cause the history to follow the renamed name.

Thank you, very kind, the steps are clearer now.
In my entity the delete button is disabled.
I can’t find anything about this in the post you suggested.
Do you know how I can delete it?

In that case, try to delete the entire device, just keep note of the entity names.
