@Ray the number of calls depend on the update intervall you set in your config. For example if you have it update every 10 minutes it will be 144 calls a day.

@sdetweil yes - all that is needed is …/2.5/… -> …/3.0/…

@sdetweil https://github.com/Tom-Hirschberger/MMM-OpenWeatherForecast/blob/master/MMM-OpenWeatherForecast.js#L53

@sdetweil MMM-OpenWeatherForecast has V2.5 as default.

@kent79 V3 is free for 1000 calls a day and unless you update the weather every minute you probably won’t reach that limit.

@kent79 from openweathermap.com:

"Dear OpenWeather user,

We would like to inform you about our plans to complete the migration from One Call 2.5 to One Call 3.0 that started 2 years ago. In line with this, access to One Call 2.5 will be finally closed in June 2024.

One Call 3.0 provides you with significantly advanced business-demanded features such as a minute forecast for 1 hour, 4 days forecast for any timestamp, a daily forecast for 8 days, including a human-readable summary, historical data (45-year archive) for timestamps, and with daily aggregation, 1.5-year long-term forecast with daily aggregation, and others."

So V2.5 is only working because openwaethermap didn’t fully shut it down even the deadline is over. It can happen any day.

@kent79 Did you get a new V3 API key at openweathermap.com? Old V2.5 keys won’t work anymore.

@kasperb what version of nodejs are you using?

what does the following command say:

nodejs -v

The module was recently changed to use a nodejs internal method to get the data, but your nodejs might be outdated.

@froboz @Ray make sure you have the following parameter in your config:

apiBaseURL: "https://api.openweathermap.org/data/3.0/onecall?"

and get a V3 API key from https://openweathermap.org/

@sdetweil I found the reason and created a pull request
