Energy Panel - Consumption/Production





I've started measuring my 3-phase home energy 4/5 months ago with Aeotec HEM3 Gen5. I've 3 clamps for each phase... My main consumption device during the day is my Swimming Pool along with PH dosing and Chlorine production machines, around 900W of instant power consumption. I used to have something  this:
Phase1: 30W
Phase2: 900W
Phase3: 50W
Total Consumption: 980W

Last week I installed 4 Solar Panels and the production energy started to be injected on Phase 2. I know have the difference between the my consumption and production on Phase2 readings. For instance... If the panel is producing 700W the readings display:
Phase1: 30W
Phase2: 200W
Phase3: 50
Total Consumption: 280W

When I shutdown the swimming pool pump and all other machines I start to have negative readings:
Phase1: 30W
Phase2. -700W
Phase3: 50W
Total Consumption: -620W

My intention is to install a 1 clamp meter right on the Phase that receives the energy provided by the solar panels and set the device on HC3 as a Production. Now come my doubts...


Q1: This device will also register and display negative readings, am I right?


Q2: Will this Production energy be taken in account as energy consumed by my house in the Fibaro Energy Panel? I am asking this because since I installed the Solar Panels, my HEM3 Gen5 started to display only the Grid consumption and not my Total consumption (Grid+Solar).


Q3: Should the Consumption  on the Energy Panel be the Total Consumption (Grid+Solar)? And in this case should I create a sort of Virtual Device (through QA) that adds the abs(production readings) from by 1 clamp meter with the total consumption readings from my 3 clamps to get the Balance value calculated correctly?



Thanks for your help

  • Is it possible to have any feedback on this or should this question be moved to the FIBARO "System Update > Home Center 3 > Update 5.090" sub-forum since this is a Enery Panel feature related subject?


    Thank you

    Hope some other users with Aeotec HEM3 Gen5 can answer your question. I just use my Smart Energy Meter, don’t need the clamps.
