I have this config:
sensor:
- platform: mqtt
name: "Mathis-Temperatur"
state_topic: "home/temperatur/mathis"
unit_of_measurement: "°C"
value_template: "{{ value | float }}"
qos: 1
in my configuration.yaml.
I have a temperature sensor connected to an esp32 c3 which sends the temperature every 30 seconds to home/temperatur/mathis and it is received, which i can see in the mqtt debugging tool and mqtt explorer, somehow it won't show up.
