i would like to suggest a feature.
So far one can only use template code in HA Widgets on android.
Maybe it is possible to add support for normal yaml, so one can create a card as in the Lovelace.
This would have vast advantages.
One could have the 5 most important devices on the phone main display for example, all controllable directly when the phone is unlocked.
I do not know how technically difficult it is, but it should be doable as other apps also allow widget creation with interaction.
