@chrisfr1976 You need to set up a Grafana Dashboard based on influx. The discussions in the evcc github (for example here) are a good starting point. Then install MMM-GrafanaChart. Config.js as described in the module documentation:
{
module: 'MMM-GrafanaChart',
position: 'top_left', // This can be any of the regions.
config: {
version: "6", // Only add this line if you are using Grafana verison 6 or greater
id: "V9usrR48j", // Only Mandartory if you are using Grafana verison 6 or greater found after /d/ in the url
host: "solarrouter", //Mandatory. See url when displaying within grafana
port: 3000, // Mandatory.
dashboardname: "pv-ubersicht-mirror", // Mandatory.
orgId: 1, // Mandatory.
panelId: 9, // Mandatory.
from: "now-1d", // use any of grafanas time-range-controls
to: "now", //
width: "100%", // Optional. Default: 100%
height: "100%", // Optional. Default: 100%
scrolling: "no", // Optional. Default: no
refreshInterval: 9000 //Optional. Default: 900 = 1/4 hour
}
