# 2.1.1.7 Notify Groups for Mobile Notifications

Notify groups are a great way to send a notifications to multiple devices at the same time. In this way if you have x devices that need a notification from an automation then you only need to make the automation once and refer to the group. This makes everything need, clear and easily scalable. So for this we assume that you already have more than or equal to two devices. For the example we use the devices that are registered with the Home Assistant companion app.

1. mobile\_app\_device1
2. mobile\_app\_device2

If that is established we will move into the GUI and create a Notify Group

1. Go to Settings > Devices & Services > Helpers
2. Here we choose the button in the right bottom corner + Create Helper
3. Then we select Group
4. Finally we select the type of group: Notify Group

Give the Notify Group a name e.g "GROUP\_NAME" and add your devices to it. In this case "device1" and "device2". If they are recognized they must appear if you click on the members button.

Then save the group and your are 1/2 way there ;))))) wohooooo!!1

What is next is going back into the terminal to access the configuration.yaml file that is located at /home/user/opt/stacks/home\_assistant/config/.

```bash
nano configuration.yaml
```

Then we will add the following notification information to this file

```yaml
notify:
  - platform: group
    name: GROUP_NAME
    services:
      - service: mobile_app_device1
      - service: mobile_app_device2

```

Then save the file and you are almost set! The only thing that is left is to restart your home assistant instance for the changes to take effect.

Then now, being officially registered and all --> you can choose the GROUP\_NAME to receive notifications for all kinds of automation's. For instance Frigate Blueprint notifications or if devices are up or down and send a notifications to all the phones defined in the Notify Group.
