Climate Groups over official group function

Hello,

i wish their is a way to create a climate group over the official group function.

There is. Read the docs. Group - Home Assistant

Yes but for that i have to fill my main config yaml… wish it would be able over the ui without filling my config

There is a lot of misleading information around about climate groups but adding something like this to configuration.yaml works, substituting the entities you want to group.

group:
  climate:
    name: 'Thermostats'
    entities:
      - climate.battery_powered_wall_thermostat
      - climate.heating_thermostat_1
      - climate.heating_thermostat_2_2
