Duplicate VRM instance after changing MPPT on OS 3.01

I've changed one MPPT from a 100/20 to 250/70. Now I have the same duplicate VRM-ID than the other one. Both have ID 291. How to fix that? I can't select one on Node-Red, neither on VRM-portal.

I don't want to return the unit, as the installation took several hours.

Any help is appreciated

Issue solved, OS-upgrade to the test-version made the trick...

For clarity:
I have exchanged a SmartSolar 100/20 with a SmartSolar 250/60. The system also has a SmartSolar 250/100.

The 250/100 has VRM-ID 291 und the former 100/20 had VRM-ID 289.

Now, the new 250/60 has obtained the same VRM-ID (291), als the 250/100. This has freaked out the system, as the reading came from both.

But issue now is solved and shouldn't appear again. Keep fingers crossed.

Best,
Wilm

For clarity.

Are both MPPTs still part of the system, or has the new one replaced to older one and the older one is removed from the system?
