since the move to UI for Helpers we can not set initial: to them via the UI and have to resort to Yaml:
input_boolean:
just_started:
name: Just started
initial: on
Aware booleans restore state. However, for certain booleans we need a fixed startup state, and not rely on restore.
Please add initial: to the UI, so we can move all booleans to UI and leave yaml.
