How to store kWh values in emoncms.org

I've just re-setup my system to use the emonTxV3_continuous_kwhtotals_noeeprom sketch and it is working great with the nodes interface. 

However I cannot find a way of permanently storing the phpfina kWh data in emoncms.org.   I have tried all the processes available ( I think ) and only the log to feed seems to post it to emoncms.org but after a power outage of the emontxV3 the kWh data in emoncms.org resets to zero.

Is there a way of storing the kWh values as an ever increasing feed that doesn't reset, similar to how the 'power to kWh' process behaves?
