Thanks Perry. I have tried to download your monitor code from your Tutorial but it wont compile because I have a TJC Nextion and I cant set up the Nextion as per your Tutorial.
The tutorial I can find is one which transmits time TO the Nextion and I am having difficulty understanding the code which is read FROM the Nextion
Do you have a more basic version which would allow me to read just one (or 2) numbers from the Nextion n0 or n2
