Monthly Kwh use in emoncms node -red

Hello ,

I 'm trying to find a way to monitor monthly Kwh use . So every month I would like to start with 0.
I will use this to put a gauge on my dashboard

Is there a way to do this with node-red and push the value in emoncms ?
Or is it possible within emoncms.?

I read a lot of topics about this , but can’t find answer.
