I have not touched it up until yesterday when I started looking into DB management on this forum, so up until then I had the default set up that comes “out of the box” after installing Home Assistant OS.
Yesterday I looked into this thread How to keep your recorder database size under control - Community Guides - Home Assistant Community (home-assistant.io) and created the recorder line in my configuration.yaml file excluding some of the non-important entities/device classes.
This is what I have there for now:
recorder:
exclude:
domains:
- device_tracker
- media_player
entities:
- camera.doorbell_sub
- camera.front_door_main
- camera.front_door_sub
- camera.garage_sub
- sensor.home_assistant_v2_db_size
- sensor.memory_free
- sensor.memory_use_percent
- sensor.processor_use
- sensor.ble_mac_50765cb7d9ea4e2199a4fa879613a492
My current DB size is over 700MB, so I do reckon that a substantial amount of data resides there:
