ashtonaut:

 

When my security system 'goes off' (i.e. the internal and external siren), does anyone know if the iOS Homekit / Home app notification is just a standard push notification, or is it (or can it be) more prominent?

 

For example, even if my phone is on silent or DND mode, I would like a 'house alarm triggered' notification to come through regardless, with sound.

 

I'm a bit hesitant to test as I'll need to set my alarm off several times to figure it out...

 

If the answer is no then I'll probably use Pushover to send a duplicate notification with higher priority.

 

To answer my own question here, I can confirm that if the alarm goes off, the iOS Home app push notification is sent through Apple's push service as a high priority, so an audible alarm sounds on your phone even if your phone is set to silent or DnD mode. This is as I expected, but useful to confirm nonetheless.
