HA Notifications wont appear in Android Auto

So for years I’ve never gotten this to work. I have worked around it by using email to SMS but ATT is closing that service, so now I need to get this working.

So I have notifications working using the automation builder and in the data field I have the following, which has reportedly worked for other people:

car_ui: true
notification_icon: mdi:garage
channel: Garage
importance: high

the notification works on my phone always, but never appears on AA. I have also tried:

car_ui: true
notification_icon: mdi:garage
channel: Garage
importance: high
priority: high

still nothing. As far as I have enabled everything else, so this should work. What am i missing?

Found this old reddit thread. OP said he got it working, so I compared his yaml to yours and the only thing different I see is that you don’t have a “ttl:” variable in your data.

Might be worth a try to add it…

That’s the thread i used to set mine up, but you’re right, i didn’t include that. Ill give it a try.

When I was googling about when pondering this, I found another thread here on the forum (which I can’t seem to find again right now) about TTL and priority in AA and then I saw that thread and it got the gears turning…

FIngers crossed…

This is a sample (somewhat) working for me

    - service: notify.mobile_app_oneplus_nord
      data:
        title: "Coming home"
        message: "You're coming home."
        data:
          car_ui: true
          notification_icon: "mdi:shield-off"
          channel: "HA above"
          importance: high
          timeout: 120
          actions:
            - action: "ACTION_COMING_HOME" # The key you are sending for the event
              title: "Tout" # The button title
              icon: mdi:home-import-outline
            - action: "ACTION_DISARM_ALARM" # The key you are sending for the event
              title: "Désactiver alarme" # The button title
              icon: mdi:shield-off
            - action: "ACTION_OPEN_PORTAIL" # The key you are sending for the event
              title: "Ouvrir grille" # The button title
              icon: mdi:gate-openoff
            - action: "NOOP"
              title: "Annuler"
              icond: mdi:cancel

For me, the notif is shown with a single button, but that’s device-specific, apparently.

I made the change and added ttl: 0 and it still doesnt work. Now, I am connected to the car and manually triggering the automation and quickly closing my phone, so its not happening naturally, but it still does not display.

The automation given right before mine has less variables, and works, its got to be somehting with my phone or HA app. What am I missing?

I just got a Pixel 9, but this was also happening with the Pixel 7.

OK, I got it fixed, and the solution is probably dumb, but hopefully this can hep someone else.

I did not have the home assistant app on my android auto dashboard, because I just don’t use it that way. But after I added it, the notifications work! Thanks to everyone that chipped in!!

you mean you unchecked it from the launcher in Android Auto settings previously? Pretty sure it gets added by default there :thinking:

correct, i gets added automatically, and since I dont use it, I unchecked it. But adding it back to the launcher fixed my problem
