Shelly Pro 3EM 1 or 3 fase

[ikorpershoek]

I installed B2500-meter in Home Assistant and use combined variable L1+L2+L3 power value from my Homewizard P1. Installed Shelly Pro 3EM as CT in my Marstek 2500 Venus and everything is working well. Now my question is, if I changed the combined power value to the three individual values in a comma-separated list like sensor.espressif_vermogen_fase_1,sensor.espressif_vermogen_fase_2,sensor.espressif_vermogen_fase_3
I don't have power-output values for the phases. Can I leave that input field empty in the configuration of the B2500 ?
