Feels Like Temperature Not Displaying if It's Zero

[pkscout]

Describe the bug
I have an alternate sensor for feels like temperature, and if that sensor goes to zero degrees (which unfortunately it does from time to time), the feels like temperature on the card disappears.

To Reproduce
Steps to reproduce the behavior:

1. create a sensor that you can manually set to zero (an input number would probably be fine)
2. assign it as the feels like temperature sensor
3. set the sensor to zero
4. see that on the card the feels like temperature is not showing
5. set the sensor to any other non-zero value
6. see that on the card the feels like temperature now shows

Expected behavior
The feels like temperature should show even if it's zero degrees. That is a valid state for that sensor.
