Help with QED command in a parallel system

[CoderMaximus]

Hey,

First off I would like to state that I'm fairly new to this CLI, so sorry if my questions sound unreasonable.

I have my PC connected to my master inverter through a USB cable, running sudo mppsolar -p /dev/hidraw1 -c QPGS1 returns info from the master inverter, and running sudo mppsolar -p /dev/hidraw1 -c QPGS2 returns info for the second inverter(slave)

Then I tried reading the QED for the Master inverter through this command and it worked:

sudo mppsolar -p /dev/hidraw1 -c QED20251222

Command: QED20251222 - No description found
--------------------------------------------------------------------------------
Parameter Value          Unit
warning   No definition for command QED20251222 in protocol b'PI30'
   ponse  (00029708ÛÖ
--------------------------------------------------------------------------------

29708Wh was the result, but i would like to know if there is a way to get the QED for the slave inverter through the same USB cable connected only to the Master inverter, the same way you can query QPGS2.

Will I need to connect a second USB cable to the slave inverter to be able to read its own QED?

Please help and thanks in advance.

Inverter Model: Axpert MAX-8000, 2 units in parallel.

2.11 QPGSn<cr>: Parallel Information inquiry (Only 48V model)

In my knolwdge this is the only parallel query command. All other query commands are single device only.

PS: For Axpert MAX-8000 you should use PI30MAX protocol (or PI30m044 I use for MAX-7200).
