Re: Cloud platform for streaming my rpi's CSVs?

I would like to share doing some research, it seems the easiest way the following and free:

my rpi's CSV -> convert to JSON multiline using python -> send to dweet.io (free) -> send to freeboard.io (use free 30 day trial)

how complicated! :evil: :twisted:

Re: Cloud platform for streaming my rpi's CSVs?

What creates these CSVs (I am assuming these are comma separated variables)? What type of display do you want? You could go for a dashboard type display using something like https://io.adafruit.com or one of the other free dashboard suppliers. You could use Python and Flask to create your own web p...

rpi 3 script for wifi+bluetooth traffic/density of population detection?

Hi there, various very old threads with approximations about this and commercial (quite expensive!) solutions such as Libelium solve this:

is there any rpi script out there that solves this problem?

Thanks in advance

Re: Any tutorial for a 100% completely reliable 3G/4G dongle with GPS?

well this is for a prototype, in case we go finally for a project we will go for the expensive Libelium solutions

I will use a 3G dongle then, or maybe several rpi's connected via wifi to another rpi with a 3G hat

Re: Autoexecution of script in .bashrc not working

/etc/rc.local is for SYTEM software, not to run scripts for users. are you running the script in background, or waiting for it to finish? a better place to launch is in the users account as part of the login shell.

Re: How would you set up auto root login + auto python progr

Thanks, I want to run the script after the auto root login, in other words, you plug the current and rpi auto root logins and then auto runs the script, hands free ;)

I think I cannot run the python script without the root login because it has output in the screen ??
