Using this repository and an ILI9341 320*240 LCD you can create your own Pvoutput monitor screen. This great website is used to log data coming from green energy systems. This screen can then be put in your livingroom to keep a close eye on how much green energy you are generating.
#Usage NOTE: The code may have a few rough edges and no comments at all. You are free to ask any questions though. This piece of software was coded together with Bob van der Linden
Make sure you have installed the following Arduino Libraries:
- [Adafruit-GFX-Library]
- [Adafruit-ILI9341] library
- [WifiManager]
- [SPIFFS]
- ESP8266 Sketch data upload
When these are installed, compile and upload the code to an ESP8266 connected via SPI to a ILI9341 LCD screen.
Pinout: ILI9341 pin ESP8266 pin MISO GPIO12 MOSI GPIO13 SCK GPIO14 CS GPIO15 DC GPIO2 Backlight GPIO0
When the esp8266 is flashed and the sketch data is uploaded to the SPIFFS, follow the instructions on the LCD to connect to the ESP8266. The first time the used WifiManager library will setup an Acces point, connect to it and use the setup to set up the Wifi network to connect to. After the connection is established. Setup and view the needed parameters, by going to the corresponding link:
IPAddess/apikey?apikey=PVOUTPUTREADAPIKEY PVoutput account api key(can be found in the user settings of your pvoutput account) IPAddess/refresh //Refresh all data IPAddess/systemid //Set the systemId which to view. IPAddess/wifisetup //Redo wifi setup IPAddess/reboot //Reboot the ESP8266 IPAddess/brightness?brightness=Number between 0-1023
When all is setup, you should see a screen with your energy source information on it, a graph from the last hours and some totals.
