Hi
I am an electronic engineer with more than 5 years of experience in the field of embedded systems. I have completed status monitor embedded systems few times, so that's why I decided to apply for the project.
Since you have strict no use of Serial, then I believe most convenient option is ethernet. In that case we can easily use raspberry pi as the our platform. Also we can use simple 7 inch touch display as the display for showing monitor status if you need. Else we can host a web service on rpi and access using IP address.
I'm confident on completing the project sucessfully and looking forward to hear from you.
Thank you
Anusha
