Energy template?

I have AMR2MQTT set up and am reading off of my power meter. I have two issues I am hoping might be solvable with a template, but I am not quite sure how to approach it. First, the sensor does not show up as an option under Grid Consumption on the Energy tab, second, it shows total consumption in KWh whereas I would prefer something like a minute by minute power consumption kind of thing. Are templates the way to go or does this need to be fixed in the integration?
