Hoping there is something silly I missing here with my custom TuyaV2 alarm Panel

Hi, I’m currently working with the new Tuya V2 integration and I’m looking at implementing a Tuya Alarm system into Home Assistant.
I have most the code done but I’m having an issue with the arming of the Alarm, from what I can see neither the alarm_arm_home or alarm_arm_away functions are being executed in the script yet the alarm_arm_disarm works fine.

This is what I know.
The Home Assistant AlarmControlPanelEntity creates correctly and shows correctly in the lovelace webui
When I change the state of the Alarm (e.g. set it active via the Tuya application) the panel alters to show the new state of the alarm.

When I tried to aim the alarm via Home Assistant it will not arm (this is either via the lovelace panel or developers call services), this is the same for the arm away and arm home
However if the alarm is armed then by pressing the disarm button or service it does disarm the alarm.
Extra info:
I have also altered the send command in the alarm_disarm function of the script to send “home” this allowed me to set the alarm as arm away and then click the disarm button on the panel and it went to arm home proving the command “home” was valid.
I have also traced when calling the arm away and arm home in the developers windows and it appears to be calling the correct functions.
I’ve also put debugging code in the arm away and arm home functions and it doesn’t seem to trigger.

This to me seems to show these 2 functions aren’t being executed in the script but HA is requesting them.

At this stage I have no idea why 2 aren’t being called?

These 2 buttons never seem to run the functions in the script

The disarm does disarm the alarm

in this event 1 worked, event 0 didn’t seem to trigger the script

Any idea why alarm_arm_home and alarm_arm_away arn’t being called in this script?
