“Measure what is measurable, and make measurable what is not.”
The line is often attributed to Galileo. Probably wrongly — yet it captures something important about our approach to energy management.
The first part is easy: PV, storage, wallboxes, load profiles — today we measure almost everything. Dashboards full of values; ideally all of them green. The second part is the hard one. What about the things that can’t be measured directly? For instance: whether a meter is still sending at all.
An electricity meter reports 42 kW. Looks fine — until you notice the value has been frozen for hours. The connection is gone, the device is stuck. That is the “unmeasurable”: not the value itself, but the silence behind it.
That’s why enmacs:FLEX makes this silence measurable too: it monitors not only which value a device reports, but whether it’s still sending at all. If a meter goes silent, you know — before the system makes a decision based on a phantom value.
An EMS is only as good as the data it decides on. And sometimes the most important measurement is whether anything is being measured at all.
