Code for disarm not working

The wiki describes it is possible to require a code for disarming through HA:
https://github.com/ParadoxAlarmInterface/pai/wiki/Home-Assistant-integration#make-home-assistant-to-ask-for-a-code-to-armdisarm-dev-branch

First of all it mentions dev branch, but at the moment the dev branch is only 2 commits behind master (I assume that's stable), and those commits are unrelated to this. So the wiki should be updated.

In any case, adding the MQTT_HOMEASSISTANT_CODE in PAI config, and adding the customize code in my HA configuration.yaml doesn't change anything. Disarm still works and doesn't ask for a code.

PS: I also tried the development version of this HA addon, but with that one, arming/disarming doesn't work at all for me. The logs don't show any obvious errors.

Start with the Home Assistant integration wiki section linked in the issue and inspect how MQTT_HOMEASSISTANT_CODE and the customize code in configuration.yaml are consumed. Compare the behavior with issues 194 and 318, then verify that disarm requests require the configured code and that the wiki no longer refers incorrectly to the dev branch.
