Invalid HEX conversion when using Uhppote.php outside of command line about uhppote

[carbonsphere]

$data['door'] should be a string instead of integer.

ex: $data['door'] = '01' instead of $data['door'] = 01;

However, I'll still add a check, just incase user decides to use integer instead of string.

Added value check to determine int or str for door parameter.
