How to replace entity in Energy Dashboard by new one without losing history

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.

Questions:

1. I guess this is confirmed (multiple times) to work that way reliably, isn’t it?
2. I thought with step 1 all the history is gone already… at least data from states table will be removed immediately, will it?
   Statistics of course remain in the database (mine collected a garbage of 53 entities already… ).
3. Is it safe to rename the entity in step 4 (so once it already catched the history of the old one)?
