Can I ask if anyone else has had this problem? I'd really like to use Telemachus for this project; I think it's a better solution for me than using something like KSPSerialIO, because I'd prefer the mod that liberates the data from KSP not be Arduino-specific. My prototype hardware mod has an LED bar-graph for total fuel, and a second that I'd like to use for the current stage fuel, but I haven't been able to get that second value from Telemachus; I'm not getting an HTTP 500 response, just always 0 for current resources.
