This is a simple api backend for a power meter reader I've build, reading blinking led of my power meter using a photoresistor and an Arduino Uno. The backend is written in node.js using express.js talking to a redis database.
See:
- power-meter-ionic for information about the ionic mobile app dashboard.
- power-meter-monitor For information about the Arduino Uno project and the node.js backend communicating with the arduino and storing the data in the redis database.
