Telegram event automation [args]

Configuration
1

Hi.
I’m trying to set up telegram trigger automation and had question.

This is my code:

    - alias: tg test
      initial_state: 'on'
      trigger:
        platform: event
        event_type: telegram_command
        event_data:
          command: '/air'
      action:
        - service: notify.tg_alex
          data_template:
            message: >
                    {% if trigger.event.data['args'][0]|float >= 16 and trigger.event.data['args'][0]|float <= 30 %} 
                    Включаю кондиционер. 
                     Температура: {{ trigger.event.data['args'][0] }}°C 
                     Режим: {{ trigger.event.data['args'][1] }} 
                     Интенсивность: {{ trigger.event.data['args'][2] }}
                    {% elif trigger.event.data['args'][0] == "off" %} 
                    Выключаю кондиционер
                    {% elif trigger.event.data['args'][0] == "state" and states.climate.air.state != "off" %} 
                    Включен, {{states.climate.air.attributes.temperature}}°C, {{states.climate.air.attributes.fan_mode}}
                    {% elif trigger.event.data['args'][0] == "state" and states.climate.air.state == "off" %} 
                    Выключен
                    {% else %}
                    Пример: /air 20 cool high, /air off, /air state
                    {% endif %}

“/air args” works as expected
but “/air” return nothing.
How to get “Пример: /air 20 cool high, /air off, /air state” after “/air”?

log

How can I solve error “no element 0”? I can add new one automation without [args] but I want make only one for each command. Please!

Exactly, it generating no args.

If I run automation like:

- alias: tg test
      initial_state: 'on'
      trigger:
        platform: event
        event_type: telegram_command
        event_data:
          command: '/air'
      action:
        - service: notify.tg_alex
          data_template:
            message: blablabla

all works, but after adding templates with [args] - error.

args generating my message at telegram. I typing “/air stats” to my bot, for exemple, and at HA its looks like

... command=/air, args=['states']>
/air 20 cool high
... command=/air, args=['20' 'cool' 'high']>

{{ trigger.event.data['args'][0] }} - 20
{{ trigger.event.data['args'][1] }} - cool

/air
... command=/air, args=[]>

please, be patient.
