Hello, I’m making a dashboard for my Tofas. I’m going to participate in trade shows, but I need to send information from Arduino to RealDash. However, I haven’t been able to create the XML file. It says the file hasn’t been parsed. Could you help? I’m sending my XML file and Arduino code. I’d be very grateful if you could help. I’m doing my own electrical installation, but I’m very new to programming.

You have a lot of segments that has no targetId nor name attribute set. That will fail the parsing of the XML.
