Hello,
I am new to Homeassistant, but I have the same error as described above. It is not only with the “power-distribution-card” but with all cards regarding energy or power flow. So it seems to me as it is not a special card issue.
Maybe some of you have experience with such an issue and can help us. The error message is as follows (in German):
"Visueller Editor wird fĂĽr diese Konfiguration nicht unterstĂĽtzt:
s.entries is not a function
Du kannst deine Konfiguration weiterhin in YAML bearbeiten."
Is there any solution yet? I have the same issue. I’m very sure that it worked back in the days when I configured the card. But now it does not work anymore because of this error.
