Hello, I see that the smartphone sensors include those related to android auto. When I have the phone connected to my electric car (Opel Corsa-e) the sensor says it is connected, but the other sensors are not available. Do you know why?
I tried looking at the car settings but I couldn’t find anything. I would like to be able to read the battery percentage.
These were discussed when originally added. Support was put in but it’s completely up to whether the manufacturer supports it ot not as to if you will see data.
Most of us don’t see anything there adn you won’t be able to change anything to make them suddenly start showing data. It either works because your car supports it or it doesn’t.
after you enable them you then need to launch the HA app in the car…every time you get in to get the data. There is no way around that but you can send yourself a notification to open the app to make it easier.
from there the sensor may stay as unavailable but may also show as unknown, look at the status attribute for each sensor to see the status if its been implemented or not. In my Subaru Ascent only the model sensor works to pull the car name, everything else is unimplemented for me.

Hello, is there any way to check if the implementation is supposed to be done in the car ? I have a Nissan Leaf 2019, and sensors from car also showing as unavailable, but I would be happy to be sure that the issue is not coming from a bad configuration in the android app or something like that 
please read my comment directly above, everything I said still applies in your research.
OK thank you very much,
but not sure to understand, is it like this :
- unavailable = car not connected
- unknown = car connected but sensor not implemented ?
Because for me everything stays unavailable …
(and I have open the HA app from Android Auto)
after you open the app, in the car. Go in your phone and check the sensor state. They should move from unavailable to unknown during that time ONLY. As soon as you turn off the car they will become unavailable
if you dont see the sensor state changing then you need to check companion app logs to see if another error occurs. Settings > companion app > troubleshooting > show and share logs. make sure to grab the logs only while the car is on ad the HA app was previously opened.
unfortunately teh app depends on the car updating the app with that information. its possible some sensors may stay as unavailable however at a minimum I think you will find the name sensor updating.
Hello,
thank you for the reply !
Just for the record, here is the info I can get while the AA is connected :
sensor.s23_ultra_niko_car_battery: unavailablesensor.s23_ultra_niko_car_charging_status: unknownsensor.s23_ultra_niko_car_ev_connector_type: IEC 62196 Type 2 connectorsensor.s23_ultra_niko_car_fuel_type: Electricsensor.s23_ultra_niko_car_name: Nissan_Bosch_01
Too bad as the car_battery is the value I would have used 
check the status attribute for the sensor, what does it say? unimplemented ? if you dont see a status attribute try waiting ad loading hte app in the car again to see if updates. Some sensors may only update if the state changes from the car
