“consoGridBASE = (IndexBASE_Sout.deltaBetween(now.minusHours(2), now))” returns “null” in version 4.3.3.1 or 4.3.2 while in 4.1.3 it returned a correct numeric value.
Of course it is with the same file IndexBase_Sout.rrd. The problem is the same with “item.deltasince()”
The item is defined as follows:
“Number IndexBASE_Sout “Index Base Soutirage [%d Wh]” <compteur_elec> (PersRrd4j, Soutirage, Index)”
In the administration page the item is of type Number and evolves well
