Nice to see someone who’s willing to try to create an app for the Danfoss Ally API. At this point I have it implemented through HomeAssistant, but that is not an ideal situation. I prefer having it integrated directly inside my Homey Pro.
There have been others by the way, and I remember one of them having some trouble integrating Oauth. I’m not aware of the details though. I hope you’ll be able to overcome the issues he had.
Besides that: I can imagine that the Github project for the HomeAssistant integration might give you some insights on how to build the Homey integration.
I have no experience in programming, but I would be happy to help with some testing when you get to that stage. Good luck!
