Translating values

Configuration
1

dear all,
I am trying to translate values from open-meteo into german using template integration.

this is the information I get from open-meteo:

temperature: 16.2
wind_bearing: 5
wind_speed: 7.6
forecast: 
- datetime: '2022-05-07'
  condition: rainy
  precipitation: 0.33
  temperature: 16.8
  templow: 8.8
  wind_bearing: 56
  wind_speed: 13.6
- datetime: '2022-05-08'
  condition: cloudy
  precipitation: 0
  temperature: 16.3
  templow: 8.9
  wind_bearing: 77
  wind_speed: 16.2

this is my configuration

  - platform: template
    sensors:
      openmeteo_currentday_condition_german:
        unique_id: openmeteo_currentday_condition_german
        friendly_name: 'Wetterlage heute'
        value_template: >
          {% set cond = state_attr('weather.open_meteo', 'forecast')[0].condition %}
          {% if cond = 'rainy' %}
            regnerisch
          {% elif cond = 'cloudy' %}
            bewölkt
          {% endif %}

and this is the error:
Invalid config for [sensor.template]: invalid template (TemplateSyntaxError: expected token 'end of statement block', got '=') for dictionary value @ data['sensors']['openmeteo_currentday_condition_german']['value_template']. Got "{% set cond = state_attr('weather.open_meteo', 'forecast')[0].condition %} {% if cond = 'rainy' %}\n regnerisch\n{% elif cond = 'cloudy' %}\n bewölkt\n{% endif %}\n". (See ?, line ?).

Can somebody help me solving this issue?
Thanks a lot!

use == at condition

        value_template: >
          {% set cond = state_attr('weather.open_meteo', 'forecast')[0].condition %}
          {% if cond == 'rainy' %}
            regnerisch
          {% elif cond == 'cloudy' %}
            bewölkt
          {% endif %}
