Utility meter with shelly 3em doesnt seem to be correct

Actually, it is working now :). And without any SQRT(3) correction or anything. I had an error in the TOTAL calculation adding phase1+phase1+phase1 not phase1+phase2+phase3. Stupid mistake in the conf. file :smiley:

Good, great

Yes, dividing with sqrt(3) was not the way to go. My initial test showed correct values by doing that however it turned out that something was wrong with my 3EM and I have now removed it from my system.
