Google home alarm backup for power outages

I use alarm from my google home to wake up, and a few days ago the power was out for just long enough to not wake me up…

So I have this idea it looks like it can work but I’m not 100% there yet and are still looking for better ideas or ways to make it better.

  1. get the alarm time from google home.

  2. collect that time every day at 23:00 or something with Tasker (in my phone).

  3. set a alarm for that time with Tasker, and when the alarm goes off, try to reach home assistant and if it cant, turn off do not disturb and ‘BEEP’ a few times.

This should work as a alarm backup for when power/internet are down, I hope.
ideas thoughts?
