i did something in UDP push of raw data from emontx shield on a esp8266 and mcp3008 … if that is of any interest to you Finished - UDP PUSH emontx. based on mcp3xxx and esp and just process the raw data on the receiving computer in realtime … am sure it can be adapted to other board types . but the biggest benifit of mcp3XXX is that it can process a higher number of CTs at a much higher frequency
