energy-price-display-iot

This little guy uses REST service https://github.com/triiberg/energy-pricings and displays the data on a tiny screen.

Config:

• find REST service URL and change it
• change Wifi creds

Hardware parts:

• ESP8266WiFi
• OLED Shield V1.1.0

Software dependencies (not sure if all of them are in use):

• SPI.h
• Wire.h
• Adafruit_GFX.h
• Adafruit_SSD1306.h
• ESP8266WiFi.h
• WiFiClient.h
• ArduinoJson.h

Problems:

• Didn't find and good HTTP lib, wrote a function instead (with blackjack and ...)

Will merge your pull requests:

• if you fix Wifi creds and REST urls
• find a bug in getData function (it works quite well imho, but not really tested)
• change delay(3000) to something reasonable, 1000 is more than enough (there has to be something because it will start diging emptiness and writes nonsense to buffer)
