mqtt in homeassistant gives by listening:
{"time": "2026-06-03 12:35:09","model": "Bresser-6in1", "temperature_C": 17.4,"humidity": 74,}
Homeassistant gives entities, but no data.
Homeassistant file editor uses

mqtt:
sensor:
- name: temperature
state_topic: rtl_433/temperature_C
unique_id: temperature_C
value_template: "{{ value | float }}"
unit_of_measurement: "°C"
device_class: temperature

- name: Humidity
  state_topic: rtl_433/humidity
  unique_id: humidity
