Use case:
- Two users have android phones, which they use as their alarm clocks.
- The alarm is set to differnt hours on different days, there is no ahead-of-time-pattern.
- When either android alarm rings, it should trigger an automation. Roll up the shutters, turn on the light, play doom music at 100% volume
- No specific requirements as to the alarm app used
How do I achieve the effect where the android alarm triggering, also triggers the automation? Note that the Android device is the master, HA is a slave and receives the signal. There is no guarantee the signal comes.
