Daily Power direct from meter readings

I'm new to emoncms and trying to get my head around the feeds etc.

My goal is to be able to see the power used on a daily basis and down to usage over the posting increment (currently every 15 mins) but I'm not sure I've got it set up correctly.

The data is currently being read direct from the meters register as the absolute meter reading and stored in a mysql database. As I have solar and a meter with import and export registers I am posting both readings. To test things out I am posting a few days data from the database using the following POST

http://emoncms/input/post.json?apikey=<my key>&node=1&time=<unixtimestamp>&csv=<import_reading>,<export_reading>

After a first send two lines appear on the input page, I have configured these as in the files attached, inputs.jpg and inputs2.jpg. The feeds are set up like in attached file feeds.jpg

I can see the data for the Log to feed and the accumulator and kWhd for the export but none of the others. I'm not quite sure if I have things setup correctly or where to look.

Is it possible to see the kWh per reading interval and how do I configure this.

I hope someone can explain what I'm missing, I have tried to find it in the docs but am still not sure.

Thanks
