Data retention to short

Configuration
1

Hi folks,

I’ve noticed that entity data can only be traced back for a relatively short period of time.

How can I extend this period?

a year would be good.

You can change this in the recorder option in your configuration.yaml

Check Recorder - Home Assistant for more information

Changing recorder’s retention period to 1 year is inadvisable. The resulting database size will be unmanageable.

There’s another, more efficient, way to store long-term data that involves the use of an entity’s state_class attribute. However this attribute is normally used with sensors. For what kind of entity do you want to store history for 1 year?
