I have a sketch for arduino thats works perfectly and refresh the page each x seconds. I need to adapt it for refresh the data, not the page. It`s a annoying blink when its refresh.
I repeat, the sketch works perfectly, it dont need any modification, only adapt to refresh the data and remove the blink.
I have worked with both Arduino and ESP8266. I have also worked extensively with websites. I would be able to quickly deliver your project in a few hours so it would cost you really less.
(Since this is part time for me, it could take a day or two for completion.)
