Notify Groups are useful to send notifications to a group of devices or even to different channels like Home Assistant Companion App, Telegram, Signal etc.

I’m using it to create a group of Android Devices I want to send notifications to via the Companion App.
# Notify Groups
notify:
- platform: group
name: "family"
services:
- service: mobile_app_mi_8
- service: mobile_app_redmi_note_8_pro
After that, go to Developer Tools and reload the Notify Services.
Now you should find a new notify service called “family” which can be used in automations.
