I have two questions:

1. could you give some lovelace examples with thermostat and/or other possibility's?
2. in my case i have only one group in my OZW/RVS, there is an option to use a second group (eg. DP 8771, 8773, 8774) i have only one Siemens thermostat (its a bit more it can configure the whole device). Would it be possible to use the second group in a virual way?

HI I use this HACS repo custom integration to simulate/integrate my boiler into climate/thermostat cards:

https://github.com/litinoveweedle/hass-template-climate

In my case configuration.yaml looks like this (you will need to change config to match your OZW entities):

climate:

      - "heat"

      - "protection"
    min_temp: 10
    max_temp: 30
    temp_step: 0.5
    current_temperature_template: "{{ states('sensor.thrs19_room_temperature_actual_value_hc1') }}"
    preset_mode_template: "{{ states('select.thrs19_operating_mode_hc1') | lower }}"
