API in local machine to determine the charge of battery in percentage of device.

Hi,

I want using the interface MK3-USB (VE bus to USB) to connect a multiplus (24I500I10) periphéral. I want to compute the charge of battery in percentage using an API in a local machine (kiosk) without network (airoport constraint).

It exists the VRM API but the problem is the impossibility to connect a remote server using the victron-connect application.

In an other side, I found this document (https://www.victronenergy.com/upload/documents/Technical-Information-Interfacing-with-VE-Bus-products-MK2-Protocol-3-14.pdf) that describe the interfacing with VE-but product MK2-protocol. In this case, we must use commands to get the device information. Is there a command th get the charge of battery in percentage?

Is there an api (java, c, ... etc) to compute these information ?


Thank you in advance.

Best Regards,

MK3

There are white papers on interfacing with Victron products. You will need to browse them to see if there is any thing you can use.

Hi,

Thank you Alxendra for your response.


Question 1: do you have idea how to use the MK2-Protocol (the commands) to compute the charge of battery?

Question 2: I suppose that we can the charge of battery with modbus-tcp feature. Do you have examples to compute the data (the charge of battery or volting, .. ect) from the multiplus periphéral?

Thank you in advance.
