Manual mqtt binary_sensor depending on more than one mqtt json message attributes

Configuration
1

Hello,

I am trying to get a mqtt json message from gdoor into a mqtt binary_sensor but I am failing with the manual yaml-config...

binary_sensor:
    - name: "door bell"
      state_topic: gdoor/bux_rx
      json_attributes_topic: "gdoor/bux_rx"
      payload_on: "on"
      payload_off: "off"
      value_template: >
        {% if value_json.busdata="XXXXXXXXXX" and 
        value_json.action="BUTTON_RING" and 
        value_json.parameters="XXXX" %}
        "on"
        {% endif %}
      # availability_topic: "homeassistant/sensor/gdoor/data/config/84_1F_E8_1B_C3_58"
      availability:
        - topic: "homeassistant/sensor/gdoor/data/config/84_1F_E8_1B_C3_58"
      payload_available: "online"
      payload_not_available: "offline"
      off_delay: 115

When trying to reload, I am always getting

Validation error: Invalid config for 'binary_sensor' at configuration.yaml, line 89: invalid template (TemplateSyntaxError: expected token 'end of statement block', got '=') for dictionary value 'value_template', got '{% if value_json.busdata="XXXXXXXXXX" and value_json.action="BUTTON_RING" and value_json.parameters="XXXX" %} "on" {% endif %}\n', please check the docs at https://www.home-assistant.io/integrations/mqtt

I have googled a lot, but I didn't get it...

The binary sensor "door bell" shall turn to "on" when the 3 json attributes from the received mqtt message match the given values. After 115s the sensor shall fall back to "off".

What am I doning wrong?

solved the problem by myself...
it must be a double equal sign to work

value_template: >-
        {% if value_json.busdata=='011011E8EFF001A0A02A' and 
        value_json.action=='BUTTON_RING' and 
        value_json.parameters=='01A0' %}
          ON
        {% endif %}
