Mistamudd Posted March 1 Share Posted March 1 I have a Shelly 3EM Pro working great (love the product ! ) but there's one small snag I've encountered. When my 3 phase device is ON, the 3EM is showing ~22kw of power - working 100% correctly . When my 3 phase device is OFF, the 3EM is showing 1.6 w of power - which is incorrect / spurious. Is there a way to set a low threshold to the current transformers so that the tiny tiny 1.6w is actually displayed as zero on the dashboard ? Many thanks Mistamudd Quote Translate Revert translation?

Mistamudd Posted March 11 Author Share Posted March 11 (edited) Just to clarify - the transformers are placed inside a metal distribution panel on the 3 phase incoming cables. When every single outlet is switched OFF and the supply current is a genuine ZERO, Im still seeing 1 or 2 watts of power on the 3EM. At a guess - this is the operational power that the 3EM is using to run. Is there anyway to set a low threshold on the measurements where this micro power demand would be reported as zero ? Thank you Edited March 11 by Mistamudd Quote Translate Revert translation?
