Just wanted to let you know I am working on this now: https://github.com/OpenGarage/OpenGarage-App.
It’s coming together smoothly actually however the initial setup will require the user to make a Blynk account and setup the project to get an auth key. Once the key is created, the app I am building takes over and manages the device without the Blynk app. In the future, we can possibly run our own Blynk server and remove this requirement.
I will try to post back once a working version is up in the stores.
Thanks,
Samer
