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. https://github.com/leikoilja/ha-google-home#sensors

  2. collect that time every day at 23:00 or something with Tasker (in my phone). https://community.home-assistant.io/t/using-tasker-with-home-assistant-v2/149366

  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?
