oh my - you have being struggling with this a long time now… soon you willrun out of flash rewrites to get that to working… I would help you more directly but I do not use emoncms so I am not that familiar. you could try my how to to get it working with espeasy and these Arduino+esp combo boards such as yours… it give you the option to send to several controllers off the shelf- including emoncms – oh well just a thought
