I got it to write a csv file but I am struggling with writing the actual value for the file for the power.
so my custom notification reads:
${sys.date},${sys.time},$(sys.node.ZY014_143_33_3.ST}
it outputs day and time correctly but the actual energy output just reads : "$(sys.node.ZY014_143_33_3.ST}"
I guess I am missing somehting?
Thanks
