Homematic (IP) Local set variable on CCU3

I am using Homematic (IP) Local from HACS store to connect my CCU3 to HA. works good so far. now I wanted to set a variable from HA on the CCU3 when my mobile device enters HOME zone. this automation code is what I came up with:

trigger:
  - platform: state
    entity_id:
      - person.stefan
    to: home
    from: not_home
condition: []
action:
  - service: homematicip_local.set_variable_value
    data_template:
      entity_id: binary_sensor.homematic_ip_ccu3_sv_zuhause
      name: Homematic IP CCU3 Sv_Zuhause
      value: "on"
mode: single

Sadly it does not set the variable “Sv_Zuhause” to “on” state. what is wrong ?

issue solved by using the automation UI. this is the code:

trigger:
  - platform: state
    entity_id:
      - person.stefan_herrmann
    to: home
    from: not_home
condition: []
action:
  - service: homematicip_local.set_variable_value
    data:
      entry_id: 0a23aa809937e5ca390e03746564986a
      name: Zuhause
      value: "true"
mode: single

I have a question there too. Would like to visualize the messages from the alarm service message on HA as with the CCU (LED blue flashing) with a light that changes color. Text output is no problem just had to enable the hidden entity at the CCU in HA. (Sv_alarm message, Sv_service message)
