chriscat thanks for the advert, I appreciate it!
I'm also present on this forum, so anybody who prefers contacting me here, please do (German or English works for me).
I'm particularly looking for help with the backend code, i.e. the connection to the server. I'm currently digging through some code by other community members to get this done in java.
The frontend, i.e. the UI, has advanced well, all using local mock data. I'm also working on some stuff that goes beyond what the original Smart app offers - will share more once i know it'll work with the backend. Stay tuned (then a separate thread).
Sorry for the OT for this quick teaser.
