Alarmo publishes its state to zigbee2mqtt/<keypad name>/set via mqtt
mode for the keypad can be one of disarm, arm_day_zones, arm_night_zones, arm_all_zones, exit_delay, entry_delay, not_ready, in_alarm, arming_stay, arming_night, arming_away
And Node-Red listens to topic zigbee2mqtt/<keypad name> for payload.action and payload.action_code from the keypad and sends the new alarm state to Alarmo.
The change node changes the keypads payload.action to Alarmo format ( disarm to alarm_disarm ect.)
The keypads alarm state (led status) is always in sync with Alarmo.
