If the entity is not included in the recorder settings, it will not be logged to the database. If you include everything (default), I strongly advise to change it and only record data of entities you are interested in.
Disabling an entity wonโt save any battery life, the zigbee/z-wave device will still send the info but you just wonโt see it.
You can do this, I donโt see any reason apart from calming oneโs OCD.
