Is this meant to be run on VenusOS locally or can you copy the attributes.csv over to a location on an external Node-Red installation?

If it is only meant for running locally then a nice feature request would be to be able to upload the attributes.csv file on an external Node-Red installation.

Is it possible to use the msg. object (e.g., via payload or topic) to hand over the Unit ID and Attribute?

Working on a Node-RED project with differents products (BBB, Venus, Cerbo and and Ekrano) trying to retrieve some register's value, I notice if the value is Uint32, the node do not report me it as it should.

Example : Register 3005 : com.victronenergy.tank_Remaining_d_m3_3005_uint32_10000_R
send me back :
: msg : Object
object
topic: "0df7a248e3493652"
messageId: "65d9c4e3ff4604ad95b6ebbf"
payload: 0
type: "uint32"
scalefactor: "10000"
enum: undefined
queueLengthByUnitId: object
unitId: 20
queueLength: 0
queueUnitId: 20
unitId: 20
modbusRequest: object
value: undefined
unitid: 20
fc: 3
address: 3005
quantity: 1
emptyMsgOnFail: undefined
keepMsgProperties: undefined
messageId: "65d9c4e3ff4604ad95b6ebbf"
responseBuffer: objec.....

But I still have 23liters or (0.023m3) in the tank !

Using standing modbus reader :

Fuel : msg : Object
object
topic: "Fuel"
payload: array[2]
0: 0
1: 232
responseBuffer: object
data: array[2]
buffer: buffer[4]
input: object
topic: "Fuel"
from: "Carburant"
payload: object
unitid: "20"
fc: 3
address: "3005"
quantity: "2"
messageId: "65d9c536ff4604ad95b6ec2f"
queueLengthByUnitId: object
queueUnitId: 20....

So It looks like the node has some register reading trouble.
I have the same troible with Date and Time register (830) reading and the Tank capacity (3001).

I mixed up the csv file that I scp'd into my node-red directory. As soon as I would drop the node onto the palette, Node Red would crash with this error:

I am just bringing it to your attention in case some error handling could be built in here rather than crashing Node Red. I will not make the same mistake!

Is it possible to run this node in Node-Red as HomeAssistant addon? I already tried everythink I could imagine.
The userDir for the addon is in my case /addon_configs/a0d7b954_nodered/
This is the directory mapped as /config in Node-Red. Even with the attributes.csv file present, the Dropdown does not show any data.
If I ssh into the Addon (docker container) I can see the attributes.csv in the userDir folder.
