Cerbo GX-S Same VRM number

Hello,

I have a small off-grid installation with Cerbo GX-S with firmware V2.93~2
With 4 VE-Direct Devices. Shunt, MPPT01, MPPT02, and a small Phoenix Inverter.
De inverter is placed with a USB device
De VRM /De
vice/Instance number is strange. 2 devices with the same VRM number.

But in my Home Assistant this a problem. Because the "sensors" of the inverter are now in de device MPPT02.

This problem started as I added an extra MPPT and set the Invertor 2 USB cable.

I saw that are same problems earlier mentioned on these forum, but the where solved, or not a functional problem.
This looks like problem with a solution with newer firmware.

But the old firmwares, en recent updates, even the 3.00~ firmware, give the same issue.
Anyone out there with a solution ?

Have you tried unplugging everything and then replugging it back in? If possible in different positions?

All cables are replugged, reboot, firmware updates.

What i can try is een other USB-cable. But on this forum are more people with simmulair problems.
