Missing: A binding for Discovergy Smart Meters! :-)

I’m new to OpenHAB 3, adding the Discovergy webservice thing was ok and it’s “online”.
But I got problems to add the “Intelligenter Stromzähler” thing, what would I enter as “Smart Meter ID” ? The ASCII Serial as written on the smart meter itself (and also provided on the Discovergy monthly mail) ??? (my Discovergy meter is from Easymeter and starts with 1ESY.…)
