Doesn’t seem to be any way to add number helpers to the android auto screen, is this right ?
While I’m on the subject of android auto, sometimes the only thing displayed is “navigation” when starting AA HA, going to another screen for a bit then back to HA it then displays everything, other times the opposite happens.
If you’re talking about the shortcuts you add to the screen - no. They intentionally only allow things that toggle on/off right now because distracted drivers.
numbers is not currently a supported domain so its different because it requires code change to support it. Use a template sensor in the meantime, you wont be able to control the number anyways.
