realtime.txt fails in raspberry Pi image

[dk6]

If you just want to access it locally, then you could create the file as you are now. Then set up Extra Web Files to copy it to the /interface folder.

(Below is untested and from memory, I'm on my phone at the moment)

Local file name = web/realtime.txt
Remote file name = interface/realtime.txt
Real-time option ticked, the rest clear

Then you should be able to access it using the URL you have above.

But no access from the internet obviously. You will need a web site for that.

i have access to the internet because the DashBoard of Cumulus has access from the router to outside world!
i just copy manual the realtime.txt from the /CumulusMX folder to /CumulusMX/interface/ and it worked!!!

sorry for my low knowledge of linux commands... but what is the real path of realtime.txt to put the right settings to extra web files to do this job automatically?

i have found it!!!

i found the path with the command readlink

dk6@raspberrypi:~/CumulusMX $ readlink -f realtime.txt
/home/dk6/CumulusMX/realtime.txt

Everything worked!!!! Now i can use the Culumus Monitor iOS APP!!!

thanks everyone for the help!!! What a great build you made!!!

You really should not make the Cumulus MX interface available to the internet, it is not secure enough.

As Paul said the paths "realtime.txt" and "interface/realtime.txt" should work, but full paths are ok.

I have always used full paths for Extra web files like C:\CumulusMX\web\xxxx until I read Mark's suggestion, and lo and behold... Mark's short form is much easier. Still learn something every day.

Enjoy,

I have successfully install manually CumulusMX in a Raspberry Pi Zero W now. I have no error reported in the logs.

I have only enable the realtime interval and the creation of the realtime.txt file.

Can you please tell me where is the location of this file?

Second step is to have access to this file from http://myhost:8998/realtime.txt to use it with the Cumulus iOS App. How can i do that?

Thanks!

Hey the x64 image all done and uploaded let me know

[dk6]

can we restart the webserver with a command? or there is a possibility to clear the cash of the webserver?

Clear the cache with a Ctrl + F5 should work.

Hey the x64 image all done and uploaded let me know

Device: Pi 3B
Image : x64

no errors.

realtime.txt updates ok.

Question: i am using the Cumulus Weather Monitor App for iOS. This app wants to read the realtime.txt. When i boot the raspberry the application reads successfully the file. BUT although the file updates successfully the iOS app cannot see any update it shows the last one. WHEN i reboot the raspberry the iOS app can see the new values and so on… IS there any way to restart only the webserver of cumulus? Anyway to clear the cash memory? The iOS app unfortunately does not have this option.

You cannot restart CMX built-in web server, but nor does it cache the files, caching is disbaled, it serves the requested files afresh each time they are requested.

Ok I understand! Can i run a second webserver in the raspberry simultaneously with Cumulusmx service; like apple or ngix?

Found it!

Thank you again guys!

Urgh - symlinks You'll have to explain the purpose of those. Unless they are in the cmx image - in that case it'll be over to Dazza.

Isn't /run a partition using ramdisk so as to reduce writes to the sdcard?

Code: Select all

I used the image too when I initially installed it.

Yes - that's the way I use it - running multiple instances of CMX and my webserver using NGINX. I run all this on a RPi 4 with a CPU load of 25-45 % depending on what's going on!
