const VRM_ID = "XXXXXX";
const VRM_ACCESS_TOKEN = "XXXXXXXXXXXXXXXX";
let today = new Date();
let startDate = new Date(today.getFullYear(), today.getMonth(), today.getDate(), 0, 0, 0, 0);
let endDate = new Date(today.getFullYear(), today.getMonth(), today.getDate(), 23, 59, 59, 999);
let start = Math.floor(startDate.getTime() / 1000);
let end = Math.floor(endDate.getTime() / 1000);
return [
{
'url': "https://vrmapi.victronenergy.com/v2/installations/" + VRM_ID + "/stats?type=custom&attributeCodes[]=Gb&interval=15mins&start=" + start + "&end=" + end,
'headers': {
'x-authorization': "Token " + VRM_ACCESS_TOKEN
}
}
];
Use http request node.
attributeCodes
Gb = Grid to battery
Bc = Battery direct use
Pb = Solar to battery
and so on. Didn't find an overview of all avail values in the docs, yet.
victron-vrm-api 0.0.11 now allows to select 15 mins interval.
