I am on the latest firmware 1.1.0 but this problem existed before for me and I forgot to report it.
The Vehicle Leave and Vehicle Arrive buttons on the Integration page are disabled (grayed out) and cannot be checked (they appear unchecked). I have both thresholds set and they show when the vehicle is present or not correctly when the door is closed. The Door Open and Door Close buttons are fine.
I have no desire to use them anyway but thought I would point it out.
Thanks for reporting this: I think those options were there and we planned to make them available but the feature was not fully implemented or tested. We can remove it next time we update the firmware.
