    1111Rearranged wiring a bit in the electric panel so two of these sensors can fit on the main feed wires.

    13 Turns out the NodeMCU only has one analog input (sigh).  Best bet now is to use a prototype shield board to mount the NodeMCU and use it as a WiFi interface for the Arduino.  This has the advantage that the libraries etc should just work, and can be tested with the serial monitor easily.  Also would make a nice platform for future things which want to measure multiple analog quantities.
     13Built firmware for Arduino to output one measurement per second on A4/A5 using software serial at 115200.
     14ESP8266 can access this using it's port... tested using the telnet/serial bridge on WiFi.
