Using HA for messaging in the car? | Home Assistant | Page 1

Okay, I don't know if this is directly related to the companion apps, but I just got a Chevy Blazer EV that runs Android Automotive OS and does not have Android Auto. It seems texting (especially with RCS) via my Google Pixel is a hot mess. Is there any way that I could use my Home Assistant as a sort of relay to build some type of messaging interface that can be accessed via the AAOS companion app on the car, and would read and allow me to respond to (RCS especially) messages that come into my phone running the Android Companion app?

Whether or not it's the Android Companion app, I'm imagining something on my Android phone passing on the new message notification to HA, which then sends a notification to my car via the AAOS companion app, with an option to reply via Voice to Text, which would then trigger an automation on my HA server to have my Android phone send the message via Google messages.

use the last notification sensor to read notification data and then you can use it however you wish

Right, I guess that's the easier part. Is there some way using the companion app that I could have my phone send a message to a recipient?

Sorry I meant that's the easier part - getting the notification from the phone pushed to to the companion app for the car. but in order to reply to the SMS/RCS message that my phone received, either Android companion app or some other app that can communicate with HA running on my Android Phone would need to be able to send an RCS/SMS message from my Android Phone.

oh we are not a default messaging app cannot reply, can only compose a message

brazen grail Dec 17, 2024, 9:07 PM

#

right, I guess it's more of an Android programming question.

vivid bluff Dec 17, 2024, 9:08 PM

#

yes from a technical standpoint we wont qualify for that

Because the main problem i'm trying to solve is that using the built-in (Google Assistant) app on the car, replying to text messages doesn't actually send a message to the correct recipient

#

we are not a full fledged messaging app with conversations etc... so we are only allowed to compose a message but not send it

brazen grail Dec 17, 2024, 9:08 PM

#

right, i want the message to be sent by the Messages app on my Android phone

#

there is support for it, but not as automated

brazen grail Dec 17, 2024, 9:09 PM

#

yeah

#

using https://companion.home-assistant.io/docs/notifications/notification-commands#activity and following the examples from googles docs https://developer.android.com/guide/components/intents-common#SendMessage

#

its a bit of an advanced feature, adn far too many use cases to list every single example but those 2 links should get you going to compose a message in the messaging app on your phone

#

probably will take some trial and error at first 🙂

#

alright cool i'll take a look at those - thanks!

#

only thinking of trying to do this within HA because HA is one of the very limited number of apps that GM has blessed to be installed on their AAOS cars.
