I currently have a clamp on my mains by the meter measuring import/export and a “log to feed / allow positive /power to kWh” calculation which feeds into my Octopus Agile App - essentially monitoring my total import
I’d like to start to monitor and graph my total kWh export which would, I think, be the same as the calc above but with ‘allow negative’
I cannot seem to do this within the input’s process list - any ideas would be much appreciated

I don’t see reset to original? Was I clear that I want both, not just to change from +ve to -ve? Anyway, what I now have is this which doesn’t seem to work
That won’t work, because you have nothing negative coming through past step 4, so step 5 blocks everything. What version of emonCMS do you have?
I see this in my emonPi:
Do you have Reset to ZERO, and follow it by + input?
What you are aiming for is to add, after the Import (positive) Power to kWh something to reset the process to the original value, then repeat what you already have but using instead the negative part. Reset to Original starts with the initial value in one step, Reset to ZERO does what it says, you then need to re-read the input with +input. Then you take the negative part and convert to kWh.
