electricIOT

IOT Device for display info of current electricity price from Spain.

Download/classify rates, and turns on a led on a nodemcu esp8266 depending on the price.

In Spain, electric rates are published everyday at 20h.

This project is a summer exercice for an 8 years child, just for fun.

How to use

Configure your wifi network and/or your mqtt server in the nodemcu sketch electric/electric.ino

Configure mqtt server in main.py

main.py must be running on a rpi or linux server. Every 15 minutes, downloads info from ree.es Red Eléctrica Española and classifies prices in 3 categories (expensive, medium and cheap). Every 5 minutes, checks current time, finds current price and sends an mqtt message with a string:

• red - expensive

• yellow - medium

• green - cheap

Schema:

Hardware

• Rasperry Pi/linux server

• nodemcu esp8266

• 5 leds, different colours

• 5 resistors

• breadboard and wires
