Note that a pin managed by HASS is expected to be exclusive to HASS.

<p>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.</p>

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