Where did my Node-red flows go? after firmware update node red is empty

Just installed new firmware on my Cerbo GX, updated from 2.80~21-large-23 (20210925...) to v2.90~12 (20220606...) which is also LARGE firmware.

After update, my node-red flows are EMPTY!! and even when I tried to start from backup, the older firmware, still empty FLOWS... Is there any way to return those?

Should the firmware upgrade clear flows from node-red or did I experience some major bug? I understand that node-red is updated a few versions up, was it 2.0.5 and after update 2.2.2 or something like that, but is it meant to clear all flows? Where to get them back...

Cerbo GX Storage Full?

Hi everyone,

I have a Cerbo GX installed in a remote system which includes a Multiplus, a few solar chargers and smart Lithium batteries. I have Venus OS Large installed and use Node-Red for some automation.

In general it has worked well and has accomplished what I need. But recently I have noticed some strange behaviours with the Cerbo not doing or reporting what is expected in certain situations.

In Node-Red, now when I go to make a change and redeploy, I get an 'out of space' error like so:

Error: ENOSPC: no space left on device, copyfile '/data/home/root/.node-red/flows_einstein.json' -> '/data/home/root/.node-red/.flows_einstein.json.backup'

I can't find any way to actually check and confirm the storage space situation and don't have physical access to the device for a little longer.

Has anyone had storage space issues with the Cerbo before? Why would it have filled up? Log files? And how can I review this?

Any insights appreciated - thanks!

Reduce charge current based on SOC Multiplus

I want to reduce the charge current from the Multiplus II based on SOC from smartshunt using NodeRec via Cerbo.

I have tried in NodeRed but cannot find a setting to change charge current.
Have anyone tried this?
I see that I can reduce charge current via an analog in and use an assistant in the MP, but this is not a desired solution.

Any advice?

Node-RED dashboard on Cerbo GX Touch 50?

@Guy Stewart (Victron Community Manager)

Is it possible to launch and display the Node-RED dashboard, directly on the Cerbo GX - Touch 50 display?

Like swiping left and right between different default Venus OS screen layouts, could the Node-RED dashboard perhaps be accessible this way, as a fourth screen layout?

Thanks, Anton

No Output nodes available on multiplus

Hi! Just started a new Node red system on a Cerbo with a Multiplus -II 3000.

I've used both Node red and Multiplus-II before but with this installation its fighting back.

I can read input nodes from the multiples just fine, but when I try to use an output node on it, there's is none. The Solar charge output node works just fine.

What am I missing? The firmware is 481 (Newest is 489)

Cerbo GX and Node-RED via Venus OS Large: dashboard functions?

Dear Victron-users,

I recently bought a Cerbo GX with touchscreen and after a few days of tweaking I decided I want more, for example a custom dashboard. Installing Venus OS Large was the best solution I was told so I installed it on the Cerbo and activated Node-RED. Via the URL and the specific port I can access Node-Red and put instances on the grid with connections etc. But..... that's where it stops for me ;-). I cannot create a custom dashboard. On all the YouTube films I watched, I see in the left column a submenu "dashboard" with for example gauges etc. but I don't see this menu and when I go to URL/ui I get a error there isn't a GUI. Can someone help me a little bit forward?

Kind regards,

Pim

Cerbo GX node red install

I would like some clarity please before I continue.

Which file do I use to do a manual firmware update, seems like this is not clearly stated in an easily accessible place. (I did look, maybe I am just unlucky in finding it.)

When one does a manual update what happens to all your settings? Do you require a settings backup before the update and then a restore of just the settings? If so then just to be clear how does one do this.
