a weather application for the raspberry pi and the Inky pHAT (https://shop.pimoroni.com/products/inky-phat?variant=12549254217811)

The script displays:

  • the current temperature
  • today's date
  • today's temperature range
  • tomorrow's temperature range
  • a verbal description of today's weather
  • weather icons drawn with math and python's drawing library

A valuable resource: https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-inky-phat

Installation

SSH into your rasberry pi

ssh pi@[IPADDRESS]

Install the Inky pHAT libraries

curl https://get.pimoroni.com/inky | bash

Copy weather.py over to your pi

scp /path/to/file username@a:/path/to/destination

Obtain a Weather Underground account

https://www.wunderground.com/

Edit weather.py and update the variables with your API Key, the closest station, and your zipcode

  • ZIPCODE

  • STATION

  • APIKEY

Set the raspberry pi to run your script every 30 minutes

crontab -e

At the very bottom of your crontab file, add the following line:

*/30 * * * * python3 /[PATH TO YOUR SCRIPT]

Comments
  • Extraneous character '6' in URL that gets current conditions

    Extraneous character '6' in URL that gets current conditions

    Line 25 has an extra '6' character after the station ID when trying to get the current conditions.

    query = "https://api.weather.com/v2/pws/observations/current?stationId="+STATION+"6&format=json&units=e&apiKey="+APIKEY

  • Add time to top line with date. Comment line fix.

    Add time to top line with date. Comment line fix.

    Since this is an e-ink display, you can't tell if the RasPi is powered on or off by looking at the display. The data on the screen may be stale, but you can't tell how stale by just having the date. Added the time and centered both. Minor fix to comment from previous mod.

  • Use variable font size based on length of narrative string

    Use variable font size based on length of narrative string

    Some narratives are long and truncate. This uses a variable font size to find the largest possible font for the narrative, from font size 9 to 30. It also changes the narrative to center justified.

    is instead of == and API

    Apart from the fact that there are several "is" instead of == to be corrected in your weather.py file, my wunderground api doesn't work at all. I keep receiving the error:

    File "/home/Pimoroni/inky/weather.py", line 20, in APIKEY = fdd56a4a142a4d######a4a142a2d68df NameError: name 'fdd56a4a142a4d######a4a142a2d68df' is not defined

    Source provided not correct? Also getting jsondecodeerror

    Thanks for this, I am trying to get it to work, however, and don't seem to be able to. I don't know why, I am fairly new to cli side of things. I had to make several changes to the code as it wasn't working for various reasons, partly because I'm using inkyWHAT.

    I have forked the code https://github.com/Tjobbe/raspi-weather/blob/main/weather.py and here is my cli error:

    pi@tjobbe:~ $ python3 /home/pi/scriptsforWHAT/weather-display.py Traceback (most recent call last): File "/home/pi/scriptsforWHAT/weather-display.py", line 29, in <module> x = json.loads(text) File "/usr/lib/python3.9/json/__init__.py", line 346, in loads return _default_decoder.decode(s) File "/usr/lib/python3.9/json/decoder.py", line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib/python3.9/json/decoder.py", line 355, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
