Hi,
I´ve tried to calculate my energy costs in a rule with the deltaSince command. On the first day everything seems to be fine, but today (after I add a new component) the log-file grows big and the values didn´t receive any update.
I´m using OpenHAB 1.8.2 on a RasPi3. In this specific rule, only Homematic components were used.
Maybe someone could untangle the knot in my head…
