@felmue Thank you for your time. I will investigate the CAN issue further and if I can get it to work on the M5Tough, I will have to use the Fire for now although I will have to make a watertight enclosure because this goes onto a tractor. A big Thank You for the uiflow example. I looked at the documentation but couldn't find it.... If I get this to work, uiflow would make it so much easier to update the code in the field Thanks again!
