Question or Bug:

Requirements

• I have updated Smartcar to the latest available version.

• I read the Known Issues and Limitations section in the README.

• I have verified that my car is compatible with Smartcar and the API is supported in my country.

• I did a search to see if there is a similar issue or if a pull request is open.

The problem

I usually have my tires at 3.0 bar, I can even confirm that in the car. However, I never saw those values in HA. Usually I get 2.7 or maybe 2.8 tops. I am wondering if there is some cap on the integration or in SmartCar itself!

Here is an example of what I got from the webhook:

`{"code":"wheel-tires","name":"Tires","group":"Wheel","body":{"values":[{"row":0,"column":1,"tirePressure":270},{"row":0,"column":0,"tirePressure":268},{"row":1,"column":1,"tirePressure":268},{"row":1,"column":0,"tirePressure":268}],"rowCount":2,"columnCount":2,"unit":"bar"},"meta":{"oemUpdatedAt":1769095268000,"retrievedAt":1769095272288},"status":{"value":"SUCCESS"}},

Thank you

As I understand it, these tire pressure sensors might need calibrating, something a dealership or authorised dealer might do.
Mine are off too, but not by much – they read a higher value than my trusty electric pump.
The problem is I don't know which is accurate and which I can trust.

My tires do read higher values than yours, so I don't think there is a cap of any kind:

Hum.. My sensors, after inflating, read exactly the same as my mini electric pump or the Gas Station Pump so I don't think they need calibrating at the moment. The strange thing to me is that I inflate up to 3.0 bar. The car shows 3.0 bar but from SmartCar, I never get those values :(

@cipnt do you remember the highest value you ever seen here? Could you do a test whenever you have time to inflate up to 3.0 and check what car says and what smartCar sends? Thank you :)

48psi was the highest ever reading I had since tracking the pressure in Home Assistant
