@finity The problem here is that it’s not my decision to make. I developed and support this OSHW project which allows users to deploy Hass-integrated touchscreens around their house. Packages are used so that they can very easily deploy one or several of these devices without editing their base configuration. I don’t get to decide for them if they are using YAML or the UI - presumably, their existing installation already uses one or the other, and so if I push YAML on them, then I break half of my user’s installations.
On my own, I’m comfortable using whatever, I don’t care if it’s YAML or UI. The people using my own project have made their own decision, and the way things are currently setup I don’t see a clear path toward supporting them in a transparent manner, without forcing them into using a configuration style they may not be comfortable with.
