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.
