I posted my problem on Stack Overflow – no answers yet. I do hope there is a good way to do this. In the meantime, I messed around with Firebase. Online tutorials were either outdated or not very thorough, so thanks to Michael’s help I got data uploading to the database within a few, simple lines. Firebase also offers remote settings, so that’ll be exciting if I can get that working, but it’s not as straightforward as the data sending I did today. Hopefully I’ll get a few answers on my S.O. thread tonight so I can start looking into that tomorrow.
