Current Power Factor

Is it possible via VRM, or even Node-RED, to see the power factor of the loads?

Searching the forums did not yield an answer, only general power factor queries

I don't think Victron report it, but you could calculate it yourself. One place the data necessary is all together on the same line - the Marine MFD app. Type 'venus.local/app' in a browser..

In theory, yes.

In practice, the 1 minute logging interval causes severe data integrity issues, resulting in a calculated that in my installation ranges between 0.18 and 4.99.

The value must be calculated at a common timestamp of real power and apparent power

That app is per second monitoring, it's local not via VRM. The sample times even then may not coincide, but if you watch it for a while you'll get a feel for the averages. There's no better way that I know of.
