Temperature sensor reports 429.2 °C

Configuration
1

I know, this is an issue of z-wave (over zwavejs2mqtt) or the devices from Fibaro. I usually ignored wrong values and I never had any false values anymore. Can I do this in Home Assistant as well?

Python script that worked with another software:

temperatureSensor = dev.states["sensorValue"]
dev = indigo.devices[678453345]  # Temperature Sensor
check = dev.states["sensorValue.ui"] #sometimes it mixed up values and reports something else than "C".
if "C" in check and temperatureSensor != 0 and temperatureSensor > -20 and temperatureSensor < 120  and (temperatureSensor < 0 or temperatureSensor > 0.09):

From zwavejs2mqtt

[37-49-0-Air temperature] Air temperature

429.2 °C

Is this possible to do directly or do I need to make a sensor template like this?

  - sensor:
      - name: "Temperature 1"
        unique_id: temperature_1
        unit_of_measurement: "°C"
        device_class: temperature
        state: >
          {% if states('sensor.v_temperature_1')|float > -20 and states('sensor.v_temperature_1')|float < 120 and states('sensor.v_temperature_1')|float != 0 and ( states('sensor.v_temperature_1')|float < 0 or states('sensor.v_temperature_1')|float > 0.09 ) %}
            {{ (states('sensor.v_temperature_1') | float )| round(1)}}
          {% else %}
            {{ (states('sensor.temperature_1') | float )| round(1)}}
          {% endif %}

Is there a way to check for the unit from zwavejs? Check if it is “C”?

You need the template as (from what I know) you cannot correct into the sensor itself…I have two corrective sensors as well
