This repo uses a template SVG to populate an information display for the Pimoroni Inky Impression.
This follows in the footsteps of Andrew Godwin's weatherboard, using a slightly different approach. I was originally put on to Andrew's work through Matthew Somerville's write up about it.
This repo assumes you've the Pimoroni Python library installed, with the example image setter in $HOME/Pimoroni/inky/examples/7color/image.py.
After that, a few bits of ruby are needed:
sudo apt install ruby ruby-bundler ruby-dev ruby-nokogiri fonts-lato
bundle install --path vendor/bundle
This software is configured through environment variables. There is a .env.example with the various settings in it. You'll want some API keys for services from
and put these into the .env
For the weather forecast you'll want a Met Office location ID. This is not the easiest to get hold of.
e.g. for Braintree (NB you'll need jq and curl installed here)
$ curl http://datapoint.metoffice.gov.uk/public/data/val/wxfcs/all/json/sitelist?key=API_KEY > sitelist.json
$ jq '.Locations.Location | map(select(.name | startswith("Braintree")))' < sitelist.json
gives
[
{
"elevation": "70.0",
"id": "350563",
"latitude": "51.8797",
"longitude": "0.5526",
"name": "Braintree",
"region": "ee",
"unitaryAuthArea": "Essex"
}
]so pick out the id of 350563 and put that in DATAPOINT_LOCATION_ID
I've decided to use Weather Underground to snarf data from local personal weather stations to give an idea of what it is outside nearby. Just find your nearest weather station, and use its ID in your .env. E.g. for Dunoon, you'd put in IDUNOO13 is your WUNDERGROUND_STATION_ID. Don't forget you need a WUNDERGROUND_API_KEY for this to work.
This uses the Admiralty Easy Tide. Simply look up the port you want to use, and then pinch the ID from the URL. E.g. for Maldon, Essex, it is 0123B. Put that into EASYTIDE_PORT_ID.
For this you need to know your latitude / longitude. There are any number of geocoding websites to use here. The results need to be decimals (rather than degrees), e.g. for Colchester, Essex put LATITUDE as 0.898 and LONGITUDE as 51.881.
You should now be able to run ./bin/update-inky.sh
This are taken from Erik Flowers's weather-icons.
I've converted them to have a 100px base size, up from 30px using rsvg-convert, so that when embedded in the output SVG no scaling is needed.
There are a couple of different SVG templates in this repo. Basically the output is generated by matching elements in the SVG by id, and replacing the text content, or linking a different image. This lends itself well to designing new displays by editing the SVG template in your favourite SVG editor.
If you add in more items, or change existing ones make sure tha the id is set correctly. In Inkscape I've found the easiest way to do this is selecting the object and then going to Edit -> XML Editor to show the element's attributes.
Example IDs are:
day-> text here replaced with day, e.g. Mondaydate-> here replaced with the date, e.g. 12 January and so on.
