Cerbo GX advanced settings and ssh commands

Hello,
I've just installed my last components in the system: A cerbo GX and Multiplus II 24/3000. Apart from these I already have MPPT 150/100 (after 2 days it will be changed to 250/100), a smart shunt, smart batt. sense, batt. protect and an 24/12 20A Orion smart.
I explored the GUI of the cerbo (via http) but I'd like to be able to control the charger parameters (if possible) which I don't see in the gui.
I will frequently need to switch on and off the Multiplus inverter. I want to do it over ssh, automatically from my linux PC, on a pre-programmed schedule.
But what's the command for this?

So here are my main questions of a cerbo-beginner:
1. How can I disable the automatic control/start of new charging of the MPPT, az it appears when I switch on the inverter, the cerbo tells the controller to start charging, then it goes to 28V (my float voltage setting of the controller before adding the cerbo was is 26.7V), absorbing *below* my previously set tail current setting of 11A, for example 7 or 8A for hours which I got mad when I see, because thus it's overcharging my batteries. They are overcharged because the net charging power is 300-400W more than all loads. My previous setting of the charger were fine tuned to my consumption for two years and I don't want cerbo to touch them. So, when the inverter starts, on controller's bluetooth page I don't see Float, but just "External control"...

2. Is there a command or a setting in a file in the filesystem that starts/stops the inverter? In addition to that, is there a publicly accessible list of devices control settings and commands under the Cerbo's ssh command line? Related to that, I also need to "read" then my controller goes to Float mode, so then I want to trigger one of the Cerbo's relays.

I'll be appreciating your help!

You're going to need to do a lot more research and training on the system, as most of this is well documented already.

I would encourage you to start by doing the online training at professional.victronenergy.com.

The modifications section is also where you need to do reading on the GX and its many integrations, and is where this should be asked.

But this section has moved to a new forum, which is detailed on the pinned announcement at the top, so we can't move this.

These very broad how-do-I style topics are generally not encouraged by our guidelines. Which is why skilling up first is important, then being able to ask focused questions.

Topics already exist for all of this, so investing time to dig around will give you enough info to be dangerous. :)

So go lookup venus large, nodered, mqtt etc.

The cerbo manual is important - see DVCC.

ESS setup manuals.
