Dynamic energy price indicator

If you use a dynamic electricity tariff (like Tibber) it is nice to know what the current and future price levels are. If you do not want to look on your phone, the project by Till-83 is perfect. Friend Ard Boer changed some of the code, as the display was not working right (our display seemed to be serpentine). 
With cheap electronic products you can make an 8x8 led matrix screen show what the prices are for the next 8 hours. 

I printed Hatrick3D's project, but it did not fit the LED matrix I ordered. So I designed a new one from scratch that fits the AZDelivery 3 x U 64 LED Matrix Panel CJMCU-8 (€8) perfectly and can be wall mounted. 
The AZDelivery D1 Mini NodeMcu with ESP8266-12F WLAN Module CH340G Lua  also fits in the case. I printed it in two colors, but you can also just print it in white. A light color is recommended to be able to distinguish the colors.
