Home Monitoring Hub Battery Backup ALERT Status

The new Home Monitoring Sense Hub comes with battery Backup life that lasts 10 hours!
This is great BUT the Hub has a speaker with no audible notification.
It should announce or beep when it switches to battery use. Then the lights on top or audible alert should be used to notify 50% and 10% left.

(Of course your internet needs backup power too to stay connected)
