The more I dig into the HA source code, the more I found cool features. Today I found showing the wind speed in the Beaufort wind scale is already implemented.
So instead of duplicating code, I just want to write something along the lines of:
Wind of force {{ states('forecast.wind_speed') | convert('Beaufort') }}
In my case, this is a response template that will be read out by the voice assistant.
And I suspect this convert filter would make some template sensors useless, just for the sake of converting the unit to display on the dashboard.
I might be able to contribute this to HA core, but I’m new to HA, let alone its development.
