Hi,
I really miss the old version of the website “weatherspark” It had an absolutely fantastic weather dashboard.
It was a old google-finance-like graph that you could scroll, to zoom in and out to increase the timescale, or left to right to shift the date at the center of the graph.
The lines on the graph shows, current temperature, historical temperature and prediction temperature.
There were bands around the temperature that would indicate temperature averages and records for the date period on screen.
If there were precipitations, it would show as another line the amounts.
In that simple graph you could get the sense of the local weather, what it’s been and what it will be, this week, this month or 25 years ago with just your mouse.
With all the weather data being collected by government and available on public APIs, is there any open source self-hosted software that has an effective interactive data visualization user interface as weather spark of old ?
Here is what it looked like, all in a single graph with NO pageloads !
You must log in or register to comment.
For forecast, you can selfhost a Open-Meteo. But note this need a lot of RAM and storage to run the weather model.
I already use HomeAssistant and it has a nice graph interface, you can add any data you want. Plus I have a zigbee temp and humidity sensor on the balcony, so I can add local data to the one coming from external sources. E.g. here is a temperature graph, blue is the temperature from OpenWeatherMap, yellow is an indoor sensor, my outdoor sensor’s battery died again… It shows daily mean, min and max for the last 30 days:

About this graph card on the ui: https://www.home-assistant.io/dashboards/history-graph/
Yes, that’s starting to look like it. Does it let you zoom out to the whole year without a page load ?
Also, does it work without a local sensor ?
There is a history dashboard where you can change the date and which sensors you want to display: https://www.home-assistant.io/integrations/history/ You don’t zoom but you have to add dates, same 2 sensors look like this there:
But it depends on the sensor if it supports this long term statistics, by default all data is saved only for 10 days, you can change these settings.
If filtering and zooming is the most important aspect for you this may be not the best solution, as this graph displays are not the best. The most powerful feature is that you can add local data sources.
Extending history by a lot isn’t recommended. A database add-on is recommended for long term storage.
I store it in mariadb
I’m not sure that you really need special software for this. Anything that can consume an API and produce graphs should be able to do it.
Guess I am making this in excel now.
To be clear, I mean something with a user interface that combines multiple aspects of the weather and lets you change the date range by scrolling.
I have not found one of those.
Have you checked grafana? Here is a related tutorial: https://ibug.io/blog/2024/01/weather-forecast-with-grafana/
Yes grafana does seem like a good framework for building such a thing. But has anyone done it ? It is quite a lot to learn so I’m curious to see if someone has made one of these self-hosted meteo application already.
Yes that’s a pretty normal graph feature for any dataviz application.
I"m seeing these options
https://weewx.com/showcase.html https://open-meteo.com/ https://meteostat.net/en/
But it’s many many clicks before you see your data.
And then the data looks like this
Static, non-interactive, no data context
Really complex and unintuitive interface that give you data, one static plot at a time
Not self hosted, but I use Windy for general weather predictions, it has some graphs if you click on a city.
If you love graphs meteo.pl has some nice graphs, but they are static, and only for Poland and neighbouring countries. Click meteogram on the top left and zoom in, than click on a red dot. E.g. this is for this week for Warsaw:

Ok, I had a look at windy, but it doesn’t seem possible to self-host Their github repo has a lot of stuff, but no web frontend https://github.com/orgs/windycom/
As for meteo.pl, they seem to use rrdtool to generate the graph, but like windy, they graphs are static, no scrolling or putting cursor on the graph to get exact values. Also, meteo.pl doesn’t seem to have any software repository ? It is just a private commercial website ? There doesn’t seem to be something to self-host ?
