Trigger based template entity based on device trigger

Configuration
,
1

I have a trigger based template sensor configured to update its state whenever the device trigger is triggered.

However what I want to do is in the state template every time the device trigger is triggered the state of the trigger based template should cycle between a few states such as: “a”, “b”, or “c”.

How can I do this?

I used an if else statement but it didn’t work


- trigger: 
    - platform: device
      domain: mqtt
      device_id: 9ab0a61f9b8564a64c5aca0e833ee399
      type: action
      subtype: off_press_release
      discovery_id: 0x001788010926c3d7 action_off_press_release
  sensor:
    - name: "Testing"
      state: >-
            '{% if is_state('sensor.testing', 'both') %}'
            "left"
            '{% if is_state('sensor.testing', 'left') %}'
            "right"
            '{% else %}'
            "both"

I think my templating skills are the problem… I never know where to add the double or single quotes

Although it still didn’t work after revising it as below


- trigger: 
    - platform: device
      domain: mqtt
      device_id: 9ab0a61f9b8564a64c5aca0e833ee399
      type: action
      subtype: off_press_release
      discovery_id: 0x001788010926c3d7 action_off_press_release
  sensor:
    - name: "Testing"
      state: >-
            {% if is_state('sensor.testing', 'both') %}
            left
            {% if is_state('sensor.testing', 'left') %}
            right
            {% else %}
            both

The problem may be because I’m calling itself in a recursive way but this is because I want it to have an initial state AND have the sensor follow a state change pattern

Update:

Got it figured out.


- trigger: 
    - platform: device
      domain: mqtt
      device_id: 9ab0a61f9b8564a64c5aca0e833ee399
      type: action
      subtype: off_press_release
      discovery_id: 0x001788010926c3d7 action_off_press_release
    - platform: homeassistant
      event: start
  sensor:
    - name: "Testing"
      state: >-
            {% if is_state('sensor.testing', 'both') %}
            left
            {% elif is_state('sensor.testing', 'left') %}
            right
            {% else %}
            both
            {% endif %}

HOWEVER if you reload just the template config it goes to unknown as it’s initial state. Just need to figure out what event occurs when you reload a config
