Hi Jim: I haven’t been following this thread but I’m excited that you are pushing through this to get your data streaming to MonitorMyWatershed! I’m glad Sara has been providing help. It occurred to me that you might reach out to Adam Gold (@adamgold) because he was using both Atlas Sci hardware and PlatformIO. He published a blog detailing his project and also maintains his own website that details what he’s designed. Perhaps there are some solutions there?
