Alerts on Android

I use a Pixel 9 Pro. I use Hubitat HSM for my home alarm and most of it works great - audio alerts thru speakers, alerts come to phone, etc.

The one thing I can't seem to get is a stable way for audio alerts to hit my phone no matter the status. I have Hubitat exempt from DND. I have Tasker set up to turn my volume up if there's an alert , but still - I wake up to find door/window alerts (kids being kids) that I wasn't notified of audibly. This is because tasker crashes or I accidentally "closed" it or Android decided to deep-sleep tasker.

Is there any fool-proof way that, no matter if I have DND on, or volumes down, to make the volume go up for ANY hubitat alert? this has been plaguing me for years, time to figure it out.
