Since the last update (0.110) the manual alarm integration (https://www.home-assistant.io/integrations/manual/) has a separate arming and pending state which is far more logical then before.
However, not all alarm integrations got this update.
What I’m requesting is that all alarm integrations using the alarm state engine be made equal to prevent confusion \ offer same options to all platforms.
