Have you set up the CM-3P75CT as a single phase meter from Victron Connect or the context menu in the GX console?

yes i setup the vm-3p-75ct for one phase only with my phone.
cerbo gx(v3.42) shows 1 phase after that, but on vrm/betavrm it’s still 3 phase, never changed for weeks

Fronius Primo shows on cerbo gx with 3 phases for whatever reason
