Some time ago I moved to using mySQL for the recorder in HA. Noticed my database is 1.6GB in size. That got me wondering, is there any low hanging fruit with regards to stuff I can exclude from the recorder without affecting HA?
For instance I use the time sensor and datetime, noticed every minute its writing its new time value… could I exclude that? This also got me thinking if there is any other useless stuff being written by default.
