It seems the HA development for the Apple ecosystem is running a few years behind.
- Only limited widget support: actions/scripts but nothing that even comes close to what is possible using in the widget-framework.
- The possibilities in the Apple Watch companion app are limited to the iOS Actions. Apple Watch widgets have made tremendous progress in the last few years.
If you look at what other iOS/Watch Apps are capable of showing, it’s a shame that the HA implemntation is just a basic list of actions with a configurable icon, color, etc.
I’m talking about graphs, data, different subwindows, etc. Take a look at the Sleep app for reference.
