Here is the project code along with some additional setup needed.

As a result of changes in OpenWeather's API and pricing, there are two versions of the code. The two versions of the code are provided below in separate guide sections.

  • One Call API - This is "free" (up to 1000 API calls/day), but requires providing credit card information when setting up.
  • Forecast API - This is free without providing credit card info.

The code was originally written using the One Call API, before the credit card requirement was added. The second version was written after that requirement was added using the different, but still free, Forecast API. It works mostly the same as the original One Call API version.

Weather Icons

The icons used in this project were inspired by this other EPD based weather project - eInk / ePaper Weather Station. They are the excellent set of Meteocons , which the author has made freely available. For this project, we converted them to gray scale, scaled them as needed, and converted to bitmap.

Open Weather Maps API Key

We'll be using OpenWeatherMap.org to retrieve the weather info through its API. In order to do so, you'll need to register for an account and get your API key.

Go to this link and register for a free account. Once registered, you'll get an email containing your API key, also known as the "openweather token".

Copy and paste this key into your secrets.py file that is on the root level of your CIRCUITPY drive. Name the entry openweather_token, ex:

'openweather_token' : 'my_openweather_token',

It'll look something like this

'openweather_token' : 'b218dde228d7be12f16bf4640208b9f5',

this is not a valid token, you have to get your own!

It may take some time for your Open Weather Maps API key to become active - tens of minutes or even hours.

Set Location

We will also use secrets.py to set your location. To do so, add new entry called openweather_location and specify either your city name and country code:

'openweather_location' : 'Thief River Falls, US',

or by using a two tuple of latitude and longitude:

'openweather_location' : (47.6062, -122.3321),

Note that negative longitude values are use for West.

You can verify your town or city is valid by visiting https://openweathermap.org/find and typing it into the box, if you get a weather report, then that's a known city! However, if you run into a situation where the city name is ambiguous (multiple same name cities), then use the latitude/longitude value to specify location.

Celsius or Fahrenheit

The units used for the temperature readings can be set to either Celsius or Fahrenheit. The units are set to Fahrenheit by default. To change to Celsius, look for this line of code:

METRIC = False  # set to True for metric units

and change it to:

METRIC = True  # set to True for metric units

In addition to changing temperature readings to Celsius, this will also change the wind readings to meters per second.

Secrets Summary

Your resulting secrets.py file should looking something like the example below, but with your specific values. It's OK if there are more entries - for other services, etc. But you need at least the ones shown here.

secrets = {
    'ssid' : 'myssid',
    'password' : 'mypassword',
    'openweather_token' : 'my_openweather_token',
    'openweather_location' : 'Thief River Falls, US',
}
Don't forget to end each line with a comma.

Installing Project Code

To use with CircuitPython, you need to first install a few libraries, into the lib folder on your CIRCUITPY drive. Then you need to update code.py with the code listing below.

Thankfully, we can do this in one go. In the example below, click the Download Project Bundle button below to download the necessary libraries and the code.py file in a zip file. Extract the contents of the zip file, open the directory MagTag_Weather/ and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your CIRCUITPY drive.

Note that there are two versions of the code located in subfolders:

  • onecall - Requires non-free account/API key.
  • forecast - Works with free account/API key.

See the code specific sections below for more detail. Only one version should be used at a time.

If you're having difficulty running this example, it could be because your MagTag CircuitPython firmware or library needs to be upgraded! Please be sure to follow https://learn.adafruit.com/adafruit-magtag/circuitpython to install the latest CircuitPython firmware and then also replace/update ALL the MagTag-specific libraries mentioned here https://learn.adafruit.com/adafruit-magtag/circuitpython-libraries-2

One Call API (non free)

This is the original version of the code, written when access to the One Call API was available with a free API key. The One Call API now requires the API key be associated with an Openweathermap account that's been set up for payments.

Older account/API keys may still work. For any new accounts/API keys that want a free version, the Forecast API version of the code below will likely be needed.

Forecast API (free)

This is a newer version of the code that uses the still free 5 Day / 3 Hour Forecast API. It attempts to provide the same informational display as the original version of the code. However, since there are some differences in the nature of the data returned by the two API's, there are some caveats.

  • The forecast is for only four days, not five. That's because one of the "5 days" is the current day.
  • Weather conditions forecasted for noon local time are used as "daily forecast". There is no "daily" summary forecast available as there is with the One Call API.
