ADE9000 and NodeMCU ESP8266

hi! i has connect the ade9000 to my NodeMCU esp8266 and i can get some values, so the first step is complete. but i was reading the pdf ug1098 and topics in this forum and not understand how can i calibrate the ade9000 and i cant get realtime readings, i must restart the nodemcu to get the correct values.
My idea is use the ade9000 to get data and send every minute to my server to show historic voltage and power graphics. i hope somewon can help me, thanks
