Live Activities in the Companion app are great, but they can’t have buttons – tapping one only opens a URL. Actionable notifications already support actions; reusing them for Live Activities would allow things like “Mute alarm” / “Stop timer” for an EV charging countdown, “Pause” for the washing machine or “Unlock” for the door – right from the lock screen and the Dynamic Island. iOS supports interactive Live Activities since iOS 17 (App Intents).
Mockup of what I mean:
Feature request: IOS Live Activity with action buttons · home-assistant · Discussion #4638 · GitHub (related: Ability to create a button in live activities · home-assistant · Discussion #4221 · GitHub) – an upvote there helps prioritize it.
