Specifically, I wanted to make changes to the ThingSpeakPublisher.h and ThingSpeakPublish.CPP. I’ve made changes on my local files to work with ThingSpeak, but I haven’t had much luck getting it uploaded on the Mayfly. I believe it’s because my platformio.ini file isn’t correct. I tried following the example found on the ModularSensors, but it seems I need to make some other changes.
