I currently have a Multiplus and Smart Shunt hooked up, standard fission, to a Cerbo GX.
My batteries do not communicate, although they do have internal BMS's. The need to be handled like any other dumb battery, settings not withstanding.
For, non standard / unsupported, reasons I need to be able to control Charge current without limiting AC input. I am using the charge current control assistant, right now, which works well.
The above is set to disable the charger when I set 0 current and that results in a Passthru state leaving Assist enabled and ready... Which is great.
The analogue input associated with the CC assistant is currently physically connected to a voltage reference circuit, just a few diodes essentially, which in turn is driven by the Cerbo GX relays.
It works but is admittedly a messy solution. So...
Dose anyone know...
If enabling DVCC, which I should probably do anyway, will allow me to control charge current, with the Node Red node, and still have the Multi go into Passthrough, as opposed to Bulk/Float with 0 current?
Are there any red flags or DVCC setup, particularly when manipulating it that I should be aware of for my simple setup? Still reading the manual but so far all the complication seem to be around ESS and/or more complicated integrated stuff.
Will DVCC and the charge current assistant conflict with each other or is the current setpoint common? (Mainly asking so I know which order to do/test things)
lastly, if I haven't asked something I should have when considering this stuff.
Any and all comments welcome,
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...
Has anyone used Node Red to send and receive SMS messages on their Cerbo GX For status and commands?
I have it working with an email plugin but sms would be nicer.
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!
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.
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?
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)
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?
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.
