Hi, my problem is not exclusively bound to edl21. I used to get the data of my energy counter by using vzlogger and the restful integration (sensor.netz…). while the edl21 is now so easy and to eliminate vzlogger I give it a try and it works well (sensor.smart-meter…) 
How to proceed with the already existing data points? I want to add the readings of the sdl21 integration to the existing restful.sensor data points.
- What is history using? Name, friendly name, unique Id
1.1) Is in case of EDL21 name=unique_ID? - What and where should be changed (see screenshots)
Thanks a lot in advance
