Hope the link to some examples will help.
* Minor changes
* Update device-specific.markdown
Expand Aeotec Z-Stick section to provide alternative "pipe to cu" syntax for enabling/disabling "disco lights" on systems where redirection to serial devices doesn't work because the baud rate on the serial device reverts to 9600 when haas isn't running.
* ✏️ Tweaks
* Adding upgrade details
Adding details here on how to upgrade and run specific versions, rather than leaving them as incomplete generic steps in the Updating page

Updates include an alternate way of turning off the aeotec z wave 'disco lights' that is known to work on the latest Hass.io and Pi configuration (using ttyACM0 instead of the the by serial id method).
Also provides additional guidance on how to properly insert the aeotec nanomote xml code into the zwcfg*.xml file.

```
pi@hassbian:~ $ sudo hassbian-config upgrade homeassistant
/usr/local/bin/hassbian-config: line 140: /opt/hassbian/suites/upgrade_homeassis tant.sh: No such file or directory
/usr/local/bin/hassbian-config: line 141: homeassistant-upgrade-package: command not found
```
when running what it currently is.
adding the dash in home-assistant fixes the issue
Found error in examples for:
- Setting up a sensor with multiple measurement values
- Setting up a switch using topic prefix and abbreviated configuration variable names
See also https://github.com/home-assistant/home-assistant/issues/20260, the --init argument makes sure that the python service does not run with PID 1 which on some host systems can not be killed, i.e. restarting the service from within the UI is unreliable without that argument.
* Updates for python36 and scl
Latest changes to installing the scl environment don't include the scl command, scl-utils is needed along w/ the proper repository in Centos7 to be enabled via RH and then downloaded to the environment which you are building and then SCL commands will work and setting python environment for bash will work too.
