@jenga Maybe you are having the same issue I am with incorrect current/hourly time & temperature conversion?

@j-e-f-f That looks REALLY tasty! Thank you for the great work!

@j-e-f-f Am I missing a way to turn off current weather alerts? Once a weather alert like high wind or snow it drops my tables down and throws other modules off.

@j-e-f-f As always, great work. 😉

As of Saturday, May 1, 2021, the free Yahoo Weather API will be retired.

So as more time goes by the free weather api’s are dropping like flies…

Thanks For this great job! 👍

@cowboysdude it would be nice if someone with knowledge could have a look at the API of www.yr.no

The forecast is very good and they are providing free world wide data.

@j-e-f-f Thanks for sharing.

Does it work on Pi Zero? In my case it doesn’t load. I just see FORCAST and then “Loading…” forever :astonished_face:
Using defaults, no changes made.

I am trying to adjust the hours under the hourly forecast to reflect a different time zone. I was reviewing the code and I see UTC references. How can I adjust this to CST?

The API returns UTC time for everything as well as a timezone offset for the long/lat you provide. The module translates UTC into local time using these two bits of information. Say you’re living in London, but you configure this module with Long/Lat for New York, then the time you’ll see is local to New York. I can’t request a different timezone in the API.

UPDATE

So quick to jump to conclusions am I… this was a bug in my code. OpenWeather documentation says the hourly time forecasts are provided in UTC, and elsewhere in the API response a timezone offset is provided. I took this to mean that in order to see local time for the forecast I needed to add the offset to the hourly time. As it turns out this is not the case. OpenWeather does not explicitly say this anywhere in the docs that I could find, but the JSON response is already translated to whatever local timezone the request was made from. So if I live in London and I make a request for weather in Chicago I’ll see the hourly forecasts in local London time, not in local Chicago time.

I’ve changed the code so that I no longer add the offset to hourly forecast times. Do a git pull in the MMM-OpenWeatherForecast directory, then restart MM. Should be fixed up.

If you set summary: false this will stop weather alerts from displaying. The OpenWeather API doesn’t return a detailed summary (usually just a single word like “Cloudy.” ) so I didn’t think it was necessary to split these two out into separate configs.

If you wanted to keep the summary, but not show weather alerts, you can set summary: true in your config and then prevent display of alerts in your custom CSS as follows:

.MMM-OpenWeatherForecast .weather-alert {
  display: none;
}
