External Nextion Display in combination with an ESP8266 NodeMCU V3 to display PiHole Stats on a Nextion 7 inch display.
In this reporisitory i used a Nextion NX8048T070 display with 7 inch. Sure, anyone can use cheaper free solutions with any free android or iOS applikations to show their friends the imposing results of your lokal PiHole installation. But i don't want every time to grab my smartphone and open the needed applikation or the PiHole Webinterface to see, if PiHole running with the current statistics. So i can placed the display on the wall in addition to my other smart home components and can see immediately, if all ok.
I looked for a suitable solution for myself on the Internet, but unfortunately I didn't find the right one for me. So I took a 3 year old project which found on Github (https://github.com/arejaycodes/piholenextion) and built it from scratch new and rebuild this from 3,5 inch to 7 inch, while his files doesn't work for an 7 inch display.
The first start and finish the planed project.
At first i fixed the NodeMCU V3 with glow behind the display. You can add an 470 μf / 35V capacitor (you have enought space
behind the display, when you use my STL Files) between the GND and 5V Nextion display connector for additionally security.
A friend from me builds the case with his nice professional 3D Printer setup for me. The STL files can be find in this
repository to.
Build in the Nextion display in the case ...
NOTICE: Please read the instructions in the Arduino project file before you run this project!
Copy the Nextion Display TFT File on a blank micro sd-card and palce them in the micro sd cardholder on the nextion display. Power on the display and you can see the update routine. If the update ready, switch off the display and remove the micro sd card from the cardholder.
As next step load the .ino file in your Arduino editor, make the needed wifi and pihole/ntp (pihole and ntp must run on the same maschine) changes and install the needed libarys, compile and upload it to your esp8266 nodemcu v3. You can also use an esp8266 Wemos D1 mini (this is smaller and takes up less space) instead of a esp8266 nodemcu v3. The connections to the display are the same.
Future request's are welcome ...
