Hi all,
How can I get this data?
Dashboard graph data.
Thanks
The data field is in relation to the time window selection “today” and therefore not a real-time variable used in Node-Red to my opinion. What you can use is the Yield data from the solar charger node and other nodes.
Hi Gerd,
In really I would like to record all my historic consumption, on my own database. The “red bar” data.
Is it possible? How to recovery my historic “Red bar” values?
I am a developer, so I can write a program to do that, if I know which service give me that values. VRM API? Which service?
Thanks in advance,
Does consumption not work? And solar yield?
Maybe make a way to download the csv data and use the information there?
Word of warning, on my Quattro the consumption seems way off, also grid import and export is off by about 5% each
Depending on your setup, you could use an ET112 energy meter.
For my batteries I had to calculate kWh figures on the fly in Node Red, which seems pretty accurate.
If you want to collect the data in separate database, why to not use VRM API to fetch them?
At the end, from NodeRED you need to send the data out to some database.
You can connect to the VRM API from any host in the world, and in my opinion it is easier to implement this that way.

You will have to set up your own api token access etc.
In node red -the custom api node in the victron pallette allows you to pull data from the api.
Excuse the pototo vision photos. (Being lazy with the screenshots today.)
Hi,
I have no problem to use API. Do you know witch API endpoint I can use to get that data ?
Thanks
The victron api using node red on a victron gx?
What are you using or wanting to use to access the api?
Link to widgets/graph endpoint → VRM API documentation
a1, a2, a3 are the attribute codes for consumption on L1, L2 and L3
