Hay mate,
Feature requests if I could.
I have had a look at the code, and im still starting out, so this is a bit above me. I will probably break it if I changed anything.

I think it would be beneficial to add the current moon phase (included in the OWM API response as 'daily.moon_phase' and have a value of "0 and 1 are 'new moon', 0.25 is 'first quarter moon', 0.5 is 'full moon' and 0.75 is 'last quarter moon'. "

Also, the Dew Point is beneficial for two reasons, one, its a way better way to state how the air moisture 'feels' and two, a way to tell if it will be dewy over night.
This is included as two values from the API as: 'current.dew_point' and 'hourly.dew_point'

IMO I think 'current dew point' and 'moon phase' could go under sun rise and sunset, if you slightly move the 'current temp' and 'weather icon' up a touch/smaller.

Looking at Pivoine31's code, I love how he has put the rain pop and amount under each day in
https://github.com/pivoine31/esp32-weather-epd-pvmod/blob/main/show.mod/pop_and-vol.jpg

So for the 'hourly dew point' if the pop and rain amount is implemented, the daily max and min could go between the temp and rain data in the 5 day forecast? There is a lot of space between that and the graph that it could move into.

Pivoine31 has also done some good work with setting a lower infill amount in the graph if there is too much POP predicted (which makes displays hate life), a WebUI to set things up and put a rain amount AND POP in the graph (as you can see in that pic above). So maybe they could get implemented too?
