 A common question is what does Port refer to, this number is the actual GPIO # not the pin #.
 For example, if you have a relay connected to pin 11 its GPIO # is 17.

-In case you have any other python scripts running that use RPi.GPIO no values will be written after the initial HASS-start.
-Setting **shared_gpio** to true will reinit the pin before each write, working around this issue.
