Since the previous answers were incorrect, I’m clarifying our need:
We need to dynamically compare the values from two power meters in real time to control the opening or closing of switches in a self-consumption solar installation.
Some (ward and co…) claim this feature already exists, but that’s not true—they don’t understand what we mean. Honestly, it’s frustrating to see so-called experts responding with misleading or incorrect information.
