So, yes this is selfhosting related. I am working on an n8n flow to pull in weather data so that I can have this data on a dashboard. I can't find any dockerized weather forecasting apps. Most of them connect to a personal weather station, which might be an option in the future. For the time being, this is a little project I'm working on.

Partial JSON snippet:

0	
json	
cod	"200"
message	0
cnt	40
list	
0	
dt	1780693200
main	
temp	29.4
feels_like	29.23
temp_min	29.4
temp_max	29.68
pressure	1019
sea_level	1019
grnd_level	984
humidity	42
temp_kf	-0.28
weather

I would like to display something like this:

spoiler

Current temperature: 23.25 °C
Feels like: 24.09 °C
Low / High: 23.25 °C / 23.60 °C
Humidity: 94%
Atmospheric pressure: 1023 hPa (sea level: 1023 hPa, ground level: 988 hPa)
Temperature correction factor (temp_kf): -0.35

Weather: Light rain
Weather code: 500
Short condition: Rain
Icon: 10d

So, this is for you devs or coders out there. I can produce the JSON data. I'm just not sure how to parse it to something meaningful. I'm sure Python will have to be incorporated, but unsure of how to proceed.

Maybe someone could point me in a direction to tuts, articles, or your own experience. Sorry the JSON data doesn't format correctly. Lemmy formatting doesn't seem to allow that.

What dashboard are you using? It seems weird to use n8n as the data should already be in json format

Just FYI the data you provided is not in json format

I'm using Homarr which has the capabilities of iframes.

Is this not JSON format?

ETA: I guess I should have posted it as such:

Is there are reason you can't just use the Homar weather plugin?

[-] irmadlad@lemmy.world 2 points 2 days ago

Well, primarily because I wouldn't learn anything. lol Plus, the Homarr weather plugin doesn't give as much detail as I would like. It works, no doubt, I just wanted something a bit more.

You could build a weather app using flask and bootstrap 5. (Flask is the backend and bootstrap is the frontend)
