SDR weather station graph
October 18, 2024, 13:52
Hey, so I am making a weather station work on my RPI3 and I am getting confused on this. Could I have like a more in depth tutorial or maybe even better a video tutorial? Here is the link in what I’m doing. https://www.agri-vision.nl/portal/projects/25-rtl-sdr-based-weather-station-on-raspberry-pi thanks for any help I get.
I already have it working in a cmd prompt but I want to access it as a graph and/or web browser.
"Then a python script using Dash (https://dash.plotly.com) is used to serve the graphs to a web browser."
You must also install this, otherwise it will not work.
Ok so the stuff I put below crouton I put in dash?
No, but the program must be installed for the script to work.
Ok, so install the program and place the scripts into python correct?
I’m new to programming so take it with a grain of salt
Or are those just log responses
No, you create a file with the name ws2sqlite.py in the directory /home/pi/bin/
sudo nano /home/pi/bin/ws2sqlite.pyAnd you have to copy the two code blocks into it.
AAAAAAAAAHHHhhhhhhh ok. I belive I see where I am messing up
I can try that out when I get off work
You’d prob be in bed by 0 hours your time but I’ll keep ya updated on questions
Yes, as I've got a bit of work to do tomorrow, I'll get some sleep.
But please don't ping me, I'll check my smartphone when I have time. And anyone who has the time and the knowledge can answer.
Ofc have a good night
Alright, so I do have another question, do I put the entire script under one tag in crouton or do they have to be on separate tags
Since only 1 script "ws2sqlite.py" is entered in the crontab, everything must be entered in this one script.
IncluDing the timing?
Like for example
Is it # weather station logger
0,10,20,30,40,50 /usr/local/bin/rtl_433 -p 69 -f 868M -F json -R 155 -T 90 -E quit | /usr/bin/python /home/pi/bin/ws2sqlite.py >> /var/log/temperature/ws_error.log
No, this is only entered in the Crontab.
Ok so is it under only one # or is there a # for each line
Under #
in one line
Ah. Ok
So I was doing that part right
So how do I create the file and paste the scripts to it?
Sorry if I’m bugging you with questions. Just new to Linux
Oh. Pfft
Mb
And after I paste the scripts into the file directory, do I run it from python or cmd
O- oh
Welp
Not at all, that's why you created the crontab.
We got a tiny problem
This link dosent work anymore
It’s the link to the rest of the values
Idk if that’s necessary or not. Looks to be
For me it works...
https://github.com/AgriVision/rpi_rtlsdr_weather_station
I think the link on the GitHub is bugged
This a different link or the same?
Ok, so add that to the script also?
Oh no
Wait
That’s a separate thing
Correct?
Yes
Ok making sure
Alright
I think that does it
I’ll keep this open in case anything comes up
Alright, so I tried installing dash and I got this
Oop hol up
Alright, I’ll try that
Ok dash is installing
With no errors
Alright, so I inputted in the cron filesystem double check if this is correct if you don’t mind
I see that your user is not called "Pi". So you would have to change that to the name your user has. And then the script is also in the wrong directory. So move the script or create a new one in the correct directory.
So I am offline.
Alright
I “think” I got it from here
Ok well, nevermind
Dash isn’t working properly
In trying to do this aswell
YEES
PROGRESS
Ok
I give up on that
I’m going to try weewx
And could use some help
Hey bro, you know coding and stuff?
Ok so, this still isn’t working for me
"isn't working for me" is not an error description. If you want help, you have to write what is not working and what error message you are getting.
Ok
So Basicly I tried another progect, it’s this one https://www.agri-vision.nl/portal/projects/25-rtl-sdr-based-weather-station-on-raspberry-pi and seems like everything is working fine until I got an error that said “sqlite3.operationalError : unable to open database file”
When I opened the server at least
Did you install the "sqlite"?
From the GitHub?
This is the file from the GitHub along with the contents
This is the scripts I copied over
To create a database, you must install a corresponding program. With Windows, you also have to install programs if you don't want to use the Edge browser, for example, you have to install another one. It's the same with Linux. If you want a database, you need sqlite, mariadb or one of the many other programs for databases.
