The update interval of 30 min will only get the latest status from the KIA server.
If the car has not uploaded anything new in the last 30min, than you will see no change.
If you want the current status, do a forced update - but be aware, that this will wake-up the car every time you do this.
Weird since Ive been using the car and the app shows different values?
Can I force an auto update entering home zone?
You could make an automation that does a forced update with the
Trigger: “Entering Home Zone”.
Action: kia_uvo.force_update
