two devices have the same VRM Id and also Modbus Id?

Good day,

I have Venus-os running on a RPI4, v3.00~32.

I noticed that two devices have the same VRM Id and also Modbus Id.

I ask this because the MultiPlus regularly loses its connection.
That is, it can be seen in Venus-OS only without values.

Unplugging and plugging the USB, or reboot of the RPI help for some time.

Also I have already changed the USB ports, always the same phenomenon.


thx for help.

ps: with the old rip3 I don’t have notice this behavior!

I upgraded one of my MPPT loader to a newer version and have the same issue. all connected vi-direct.
The VRM number and MODBUS are now the same as my SMART Shunt.

Cerbox S-GX (C014) v. 3.00-32 MODBUS ID 100
Smartshunt 500A (v4.14) VRM 279 MODBUS ID 226
BlueSolar Charger MPPT 100/15 (v1.61) VRM 279 MODBUS 226
BlueSolar Charger MPPT 100/15 (v1.61) VRM 278 MODBUS 100

The old MPPT-Charger had MODBUS 223

Is the only solution a total factory reset ? Or is there a quick fix.
