Namespace ... undefined

Hi,

Still trying to understand templating …

I’ve read the Jinja docs but … I misunderstand how the use of namespace(var=val), or may be it’s the scope.

The assignment ’ set ns = namespace(…’ is OK, no error
But when trying to use in -service:rest_command, the error ‘ns undefined’ raise !

What I want to do is :
set/define a variable and be able to use it later, in another service (same trigger …)
How to do that ?

I guess I also misunderstand the ‘embebdment’ and interactions of/between differents items like service: , action: …
Any ‘for the noob’ docs on this subject ? Thanks for a link I would be able to understand …

alias: 'rhasspy SetLight'
  trigger:
    platform: event
    event_type: rhasspy_SetLight
    #event_data: 
    #   piece2: piece
  action: 
    - service_template: >
        {% set action = trigger.event.data.action %} 
        {% set niveau = trigger.event.data.niveau %}
        {% set ns=namespace(test="test") %}
        {% if action == 'allume' %}
        light.turn_on
        {% elif action == 'éteint' %}
        light.turn_off
        {% else %}
        chabada
        {% endif %}
      data_template: 
        entity_id: light.bureau
    - service: rest_command.tts
      data_template: 
        payload: >
          {% set piece = trigger.event.data.piece %} 
          {% set action = trigger.event.data.action %}
          j'{{action}} la lumière de {{piece}} et {{ns.test}}

Thanks for help !
