Sorry but I don’t really understand your question.
Are you successfully connecting to the API? If so you should see all the topics and not only three of them. Maybe share your Config for this integration.
As I mentioned in other responses I assume you need to use the API integration because your Home Assistant instance is not local to the Victron installation? Is that correct or are both on the same site in which case better to use modbus.
I can connect to the API but i cannot see all the values shared in the app, that i think uses the same api to show data.
I’m interensted in the output load measurement of the mppt in wich there is power from the battery that i want to monitor over night. But i cannot find it in any endpoint that has the load output of the mppt. So the question about.
It is not local because too much power requirement against my long lasting objectives. So i wish to not use modbus. I could create a vpn and collect modbus but if it can be done throught api i would prefere it.
Are you using something like MQTT Explorer to view all the topics exposed? If you want help you need to provide more info.
No, I’m not using the mqtt explorer. I use curl call directly and see results by sight and chatgpt.
I will try mqtt explorer at that point. But it is a local lan option. I wish to contact the API on web and extract info from it.
Wich info do you need?
I had many more values from the API endpoint. The endpoint stats has some specification also like venus, live_feed ecc… i tried anyone but cannot find desired values. Here is the variable table builted with chatgpt but not verified by me. Anyway lots of values semmed not available and, the output load, value of my interest, is not present seems.

I don’t understand/know what “ree by sight” is and how chatgpt would be useful here, but then, I don’t know much.
When I used the API I used Postman to get the full output of the call and sifted through the output to find what I needed.
But if you use MQTT to setup and debug it can go faster, I guess, and you have an MQTT broker on the Victron GX device itself (CCGX or Cerbo whichever you are using). You can then use MQTT Explorer, and once you connect it to your MQTT broker you will see what there is to see i.e. all the topics published. Just follow the instructions of section 3 here and let us know what you find out. Once you get is sorted out then you know which topics you need and where to find them.
If you want to share info maybe start with your config and the output of your API call. Hide the token.
Not sure if my video at https://youtu.be/dlvlhou70VA?si=oG_Kt0j17IlWsrhq&t=2654 will help - I was using Modbus to query the registers. But maybe the explanation will also help give some context to getting the values you need.
I apologize for any confusion; I’ve just edited the post to enhance its clarity.
I used ChatGPT to organize the API requests (curl prompts) and interpret the results in order to create sensor code for Home Assistant. Additionally, it helped me identify and sort the different variables provided in the API response.
I realize that I may need to improve my understanding of MQTT technology, I cant understand why could be faster to debug if i’m talking with the VRM cloud, so I plan to study it further.
Currently, my setup includes VenusOS running on a Raspberry Pi Zero W installed in my van, which is connected to an MPPT charger. This allows me to log data and send it to the cloud. VenusOS is connected to the internet via a local Wi-Fi network provided by a USB LTE modem. I could potentially connect Venus to a VPN and utilize either Modbus or MQTT. I’ve experimented with Modbus locally for a short period.
here follow an example of API request and response
curl --request GET \
--url 'https://vrmapi.victronenergy.com/v2/installations/XXXXXX/stats?type=venus' \
--header 'Content-Type: application/json' \
--header 'x-authorization: Token xxxxxxxxx'
