Send current power from efergy unit to emoncms?

I already have an efergy energy monitor and am wondering if it is possible to export readings from that to the emoncms software? Normally I would read the information from but would love to use emoncms as it is very clean and would like to have a tablet on my wall showing realtime energy usage. The efergy site does have an API. Anybody manage to do this? Thanks for taking the time to read.
