History stats sensor - does it need recorder?

Hi,

Does the sensor requires that the tracked entity will be in recorder, or it collects its own data from the sensor changes (which means recorder is not needed)?

Thx!

I am not expert but i think all history data erase after some days.Try history date to see how far back you can go. I think the default is 7 days. So u use recorder to alter this value . mine is like that (maybe my value is too much but i am experiment for now)

recorder:
purge_keep_days: 300
