publish_state excepts float

[dansity]

Hi,

When trying to flash it the Beaufort wind scale produces error as publish_state excepts float instead of char. It might be something that has changed with updates over time.

/config/esphome/weatherstation.yaml: In lambda function:
/config/esphome/weatherstation.yaml:77:40: error: cannot convert 'const char [2]' to 'float'
   77 |           id(wind_scale_code).publish_state("0");
      |                                        ^~~
      |                                        |
      |                                        const char [2]

github messed up the indentation, attached a screenshot for clarity
