Hello,
Is it possible to register old history data (from personnal record) to an entity?
Specially prior it has been set as to be include on the recorder and furthermore before it’s creation on Home Assistant.
Hello Tank,
Not to my knowledge.
You are asking for trouble growing your database very large and storing long history data anyway. The database’s base function is short term storage of what is happening and what happened recently. It will store longer term data but that starts slowing it down sooner that you would think. Also at some point the data is converted to LTS and is a sample of what was there. originally.Pushing history data to something like influxdb is the recommended method of storing history.
Imho OP wants to add a record(s) into DB with timestamps earlier than the HA DB was created.
But may be I got the question in a wrong way.
Probably it is possible with some external intrusion into DB to add records manually.
