kandi X-RAY | VitoWiFi Summary
Arduino Library for ESP8266 to communicate with Viessmann boilers using a (DIY) serial optolink. Based on the fantastic work on openv. Check out this wiki for a simple hardware implementations. This library is non-blocking This also means that the use of blocking code is not supported. Since we're talking serial @4800 baud, we would be wasting precious processing time while reading and writing to the optolink. Furthermore this library is useable in async or non blocking frameworks such as the marvellous Homie for esp8266 framework or Blynk.

QUESTION
I have js files Dashboard and Adverts. I managed to get Dashboard to list the information in one json file (advertisers), but when clicking on an advertiser I want it to navigate to a separate page that will display some data (Say title and text) from the second json file (productadverts). I can't get it to work. Below is the code for the Dashboard and next for Adverts. Then the json files

Install VitoWiFi
For Platformio: see the Platfomio lib page for VitoWifi
Assign the serial interface connected to the optolink. Pass by reference. For ESP32 you also have to give the two pin numbers: setup(&Serial, 21, 22). The serial interface will be set to 4800 baud, 8 bits, even parity and 2 stop bits by vitoWiFi. Set the function to execute when data is received when there is no callback defined for the currently processed datapoint. The callback has the following signature: void function(IDatapoint*, DPValue).
IDatapoint.setWriteable(bool) to make to datapoint R/W instead or RO by default
IDatapoint.setCallback(Callback) to assign a custom, per datapoint, callback handler. The signature is the same.
VitoWiFi.setLogger(Printer*) so vitoWiFi can print messages for debugging purposes.
VitoWiFi.enableLogger() or .disableLogger() enables or disables logging
