I'm still pondering this. I'm in the US and for better or worse, the default unit here is F. It should be a one-time change and not a big deal, but I believe over half of the AirGradient units are located in the US, although I can't speak to which ones are running this ESPHome based firmware vs the stock firmware.

I feel that in scientific communities, SI units are dominant. I guess AirGradient also defaults to Celsius:

• Specs: https://www.airgradient.com/indoor/
• "default is Celcius": https://www.airgradient.com/blog/airgradient-diy-display/
• airgradienthq@7ed5bd8

Would be interesting what https://app.airgradient.com/ defaults to. I did not try because I did not find a "delete user account" button to clean up the test user again.

https://en.wikipedia.org/wiki/Fahrenheit gives a nice overview which countries still default to Fahrenheit ;-)

I believe that the Dashboard changes the default depending on what country you are configured with.

I know the AirGradient repo's ESPHome config defaults to C, as that was the one thing they changed when they forked from this repo.

I know it probably should default to C, just give my American stubbornness a bit to soften. ;)

As an American, I prefer 'F' as default. Freedom units are best units. :) Edit: Though, default to C makes most sense. I concur. That said, I'm going to immediately reverse the change on mine. ;)
