bad cabin temp sensor?

I have notice the cabin temperature would raise to sync up to the temperature setting but the cabin is no where near that temperature. example, outside temperature is 18c, i set the cabin temperature to 27c and monitoring the tesla app the cabin temperature would slowly raise up to 27c but the vent still blowing cold air.

Nothing is blocking the temperature sensor opening, so can it be a bad temp sensor?

I recommend setting the temp when it is comfortable, regardless of the setting accuracy. I think my car is incorrect as well, but it still seems to reach and hold whatever display temp is comfortable to me

In my M3 it takes about seventeen minutes for the temperature sensor to accurately display the outside temp after leaving my garage each morning. So, if the temp is quite warm in my garage, but it is cool outside, I wonder if this adversely affects the temp setting.

The way it is now, the only way for me to get heat from the vent is to set the temp to HI, this seems to overwrite the temp sensor and force heat out.

So I took off the Cabin sensor and found something odd, how is the app able to report interior temp when I unplugged it? App is reporting 20c and the obd2 app reporting 86.5c when unplugged. Even the exterior is 26c on app and 27c on obd2 app.

Plugged back in the cabin sensor and the obd2 app read 21c which is correct since I blasted the ac on LO for awhile but after setting the temp to 27c, you can see the tesla app interior temp raise to 25c quickly and the air from the vent is warm vs hot which you would expect since the cabin temp is only 21c as per the sensor.
Looks like to me there must be another sensor that controlling the HVAC?
