I was working to Build up a System, which shows me Time, Temperature and Solar/Heating Datas.
Hardware:
- ESP8266
- Adafruit BME280 Humidity + Barometric Pressure + Temperature Sensor Breakout over IC2
- Nextion Enhanced 7" Display NX8048K070_011R
- Resol DL2
- Solaredge with enabled ModbusTCP
- Netatmo
Function NTP: Nextion Enhanced is running with an RTC Clock. The Clock will be synced with NTP at startup.
Function Temperature / BME280: Temperature is pushed over IC2 every 30 seconds from the BME280 to the Arduino
Function Resol vBus : The Communication is established over HTTP with the Resol Datenlogger DL2. The Datas are convertet from a JSON Table. It will be synced every 60 secons
Function Display: The Display has an own HMI. It gots only the Signals over UART from the Arduino DUE (Serial2).
Function OTA: The Controller can now be Updated over the Air. Just use Webbrowser to Upload Binary Sketch.
Function SolarEdge: Getting Datas from Solaregdge Inverter to visualize current Power and Consumption.
Function MQTT: Getting Datas from a MQTT Server. I use that function to read in our actuall available water at the storage.
Function NETATMO: Getting Datas from Netatmo Weather Station.

The Libary ITEADLIB_Arduino_Nextion needs the latest Pull request (29) to Update the RTC-Commands.
On File "NexUpload.cpp" of this Libary you have to disable line 17 (//#include <SoftwareSerial.h>)
