I’m currently implementing some stuff regarding energy monitoring and facing an issue if I use groups with units of measurements and functions.
My idea was to have a group item that shows me the total energy consumption by summing up the items of this group. Unfortunately this group always has the state UNDEF. If I remove the UoM it is working fine.
Group:Number:Energy:SUM Power_Total Number:Energy Power_Device1_Total (Power_Total) Number:Energy Power_Device2_Total (Power_Total)
Since I didn’t find any example using UoM and functions on groups I’m wondering if this is supposed to work or just not supported?
