Small project to show dynamic hourly energy prices from Tibber on a simple LED matrix. First column is the current hour, the other colums show the next 7 hours. High/low are the max/min price for the next 24 hours. Colours are the price levels estimated by the Tibber API.
##Installation instructions:
- Connect the LED matrix to the board (power, ground, data to PIN D3)
- Modify your Tibber API key, WiFi settings in the settings.h file
- And compile/upload the project with the Arduino IDE
##Hardware required:
- ESP8266 or similar board with WiFi (WEMOS D1 in my case)
- Neopixel / WS2812 compatible LED matrix (8x8)
- Picture frame / box
Hardware cost: Electronics around 10 Euro
##There is also a 3D-printable case created by Hatrick3D that can be used: https://www.printables.com/de/model/908102-8x8-led-matrix-display-as-energy-price-indicator-f
##Final result:
