Instrument Power meter with a WIFI enabled microcontroller that publishes to a MQTT server. ( like https://www.mysensors.org/build/pulse_power but transmits collected data over WIFI )

Use NodeRed to build dash board showing power usage in real time. ( https://www.npmjs.com/package/node-red-dashboard )

Coordinate data with other power consumer IOT devices ( hot water heater, AC compressor, air handler, Atic fan) to manage power consumption.

Need help with prototype device that can be deployed to a AC motor and calculate power consumption, and NodeRed dashboard design
