Emoncms - define/increase decimals

I’m using the emoncms integration to get my values for power and water.
However, it seems that i’m loosing some precision:

  • in emoncms the feed is in m3 and it has a precision of 3 (X.XXX - so up to 1 liter)
  • in homeassistant, i’m only getting of precision of 2 (X.XX - so up tot 10liters)

If i increase the precision of the sensor in homeassistant, it’s always a 0 at the end. So i’m guessing that the import of the emoncms is only up to 2 decimals?
Can i change this somewhere?
