I set up a notify group for each of us. I use notify.me and add/remove the devices as needed.

notify:
- name: me
  platform: group
  services:
   # - service: mobile_app_pixel_2_xl
    - service: mobile_app_pixel_6

- name: her
  platform: group
  services:
    - service: mobile_app_iphone

Then you can use it like any other service:

service: notify.me
data:
  message: Test
  title: Alert!

If you like the idea of asdf, I would recommend looking at mise. It does all the same things (and more) and is much more performant in my experience.
