I use now AccuWeather and Openweather together - to get the best of all free api calls together.
Accuweather is used hourly for daily forecasts and current weather incl. moon phase etc.

Openweather is used for hourly forecasts.

My dashboard is only visualised with pictures. :wink:

I couldn't find an explanation of how OWM calculate their moon phase figure.

But maybe you can see how it compares with the % illumination figures at http://www.astronomyknowhow.com/month-percentage.php

I have been all over the net trying to understand the differences in illumination and have a few ideas but the different number of days, 27 -29 for a complete moon cycle is confusing!

I am current here:

I will have to look at this over a period of time to determine what inaccuracies I have. The illumination percentage I have in Node-Red does not agree with my Huawei watch. When I looked yesterday if I increased the Lunar Cycle Day in my N-R by one, it agreed with my watch.

I am finding the the Cloud Cover data from OWM hopelessly inaccurate, it was showing 0 this morning for my location when to my eye it was about 80%!

As any fool (ie me) knows, a lunar month is 28 days. But as it turns out, it's not so!
Wikipedia says the interval between successive full moons is 29.53059 ± 0.29167 days.

I wonder if you get a better estimate of cloud cover by centering your API request on the nearest commercial airport or military air base, where they hopefully have accurate sensors. How frequently do they report though? Of course cloud cover is a tenuous concept :grin:

It's very satisfying to be able to display free weather data in a browser dashboard. I suspect it's best not to look too closely at how accurate it is.

if you want to know the weather... look out the window... :sunglasses:

Now that's a good idea.

I do have bigger plans for the future in the solar system in our camper.

That's so old fashioned!
