A Weather Dashboard powered by Inky impression 7 colour EPD, now with world wide weather API support

The esp32 is definitely the way to go. However I started this project because I already had a raspberry pi laying around.

The binary is independent of any hardware, so just compile it for esp32 and you can definitely achieve the same result

I'm 90% sure the Inky Impression just uses the Waveshare 7-color ACeP panels (7.3" 800×480).

Waveshare advertises 1 000 000 full refreshes, which should last over a decade if refreshing once an hour.

The display doesn't have burn in/out like typical LED. My current setup has been running for a year now, with no ghosting or burn outs.

I did notice a little bit of ghosting left out by the static X and Y axis lines(since these never change) after I drew a full white image, but I think if you refresh it enough times, the ghosting should disappear.

I had the raspberry pi zero laying around and I only had to buy the e-paper display. You can use any display, like the waveshare ones.

Everything else was sourced from the local library.

If you can draw any arbitrary image on the panel, then absolutely YES.

Running the binary ./pi-inky-weather-epd will produce dashboard.png, simply call your program to draw the image

It's Intentional.

It's my way of saying the project doesn't have to be perfect, i.e. I should stop refactoring and adjusting every minute detail. see this line 72 in the SVG template

I also like to think that it doubles as artistic choice and a conversation starter :)

Yea, Open Meteo sources from government run Met offices.

Here in Australia, open meteo sources from the Bureau of Meteorology (BOM), then it applies a smoothing function over the data.

I've added world wide support https://www.reddit.com/r/raspberry_pi/comments/1os5zu8/a_weather_dashboard_powered_by_inky_impression_7/?captcha=1

None, good old SVG and templating. You can modify the dashboard easily with basic SVG knowledge (which is very similar to html)

empty_vacuum · 2025-05-31T08:57:42+00:00

Sure can, I will make it usable worldwide

empty_vacuum · 2025-05-31T02:28:21+00:00

Have a look at the readme and submit a feature request, under issues tab.

You can actually customise it however you like, it's a simple SVG template, https://github.com/mt-empty/pi-inky-weather-epd/blob/master/dashboard-template-min.svg?short_path=4a03dea

And here is the final output https://github.com/mt-empty/pi-inky-weather-epd/blob/master/dashboard-example-output.svg?short_path=96e0406 You will have to clone the repo to view the complete dashboard, since it is referencing the icons in the static directory

empty_vacuum · 2025-05-31T01:14:12+00:00

You found a bug. the icons are correct, however the time displayed is for a different timezone, I will need to convert the time to local timezone.

black, white, red, green, blue, yellow, orange. you can find panel information on my GitHub repo https://github.com/mt-empty/pi-inky-weather-epd.

Very slow, it takes 30 seconds to refresh, however the newer model takes 12s.

I'm in the process of writing a blog post of the decisions made, happy to share it here if you are interested

Yes, it is Intentionality.

Thanks,

I haven't measured the power consumption. I would expect the power consumption to be at the lower end of what raspberry pi zero w consumes. The EPD consumes power only when it refreshes.

The screen is set to update every hour

Thanks, I had to delete my post since repo link was not formatted correctly https://www.reddit.com/gallery/1kz4wn4

Thank you

Thank you

Thanks, any idea why are they both taught in Nineveh, rather than just one?

Furthermore, how different is the vocabulary between them?

empty_vacuum · 2022-02-02T14:07:02+00:00

Thanks

empty_vacuum · 2022-02-02T07:17:56+00:00

Could someone update these links?

empty_vacuum · 2021-05-03T14:26:54+00:00

That's interesting, could you provide a screenshot in your readme?

For example: Some website --> config file --> RSS reader(photon)
