Hello,

Does anyone already install Thingspeak on a Raspberry ?

I'm looking for a light and easy reusable install.
If not possible on RPI, what is the best distri to use in VmWare ?
Ubuntu server ?

I use VMware and VirtualBox, and the easiest Linux distributions I've found to set up are Ubuntu and Debian.

I have installed the ThingSpeak server on an Raspberry Pi using this script: https://gist.github.com/abythell/8225124 . While I can confirm it does run, I cannot speak to the performance, such as how it would perform with many simultaneous Updates or retrieving very large Feeds.

Great
Many Thanks
Works perfectly.

Two more question :
- how I can export more than 2 days values from thingspeak.com to import on RPI ?
- how can I configure the rail server to start at RPI Boot ?

Many thanks again

Hi,
I found how to launch the server at startup.

But I've still a problem to backup datas from Thingspeak.com to the raspberry.
I tried : http://api.thingspeak.com/channels/9681/field/1.csv?results=8000
But I got an error

Any idea ?

Thanks

The proper way to start the Rails server on boot would be to use an initscript, however the quick and easy way is to add the following to /etc/rc.local:

(cd /home/pi/thingspeak; /usr/local/bin/rails server -d)

This line should appear before the final "exit 0" line and assumes the ThingSpeak application is found in /home/pi/thingspeak.

wheras with "timescale" it works : http://IP:3000/channels/1/charts/2?timescale=10&days=1

Hi, I am trying to install ThingSpeak in a Raspberrian Pi with a Debian distribution.
I am following step by step as in https://github.com/other/thingspeak
When I get to rake db:create I have an error, any idea?
Thanks,
Rodri

Hi Rodri,

The location of your MySQL socket needs to be set correctly in your "config/database.yml" file. Here's the line you need to change: https://github.com/other/thingspeak/blob/master/config/database.yml.local#L27 . The location of the MySQL socket varies between systems, so you may have to search around to find out what works for you specifically.

Thanks Lee,

I tried with every location and nothing. Here paths where both files are stored, wich one should I use?

pi@raspberrypi ~/thingspeak $ whereis mysqld.sock
mysqld: /usr/sbin/mysqld /usr/share/man/man8/mysqld.8.gz

pi@raspberrypi ~/thingspeak $ whereis mysql.sock
mysql: /usr/bin/mysql /etc/mysql /usr/lib/mysql /usr/bin/X11/mysql /usr/include/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz

Hi Rodri,

You can try running "mysqladmin variables", or look into your MySQL configuration file (usually at /etc/mysql/my.cnf) for the location of the socket.

Hi Lee,

Hi Rodri,

You may have some malformed data in the request you're sending. You can try using a different webserver for you requests by issuing a command such as:
rails server webrick
instead of just:
rails server

Hi Lee,

Thank you very much, with rails server webrick it is working perfectly!!

Last question, I want rails server webrick run after a boot automatically, do you know where should I add this line? add it to /etc/rc.local?

Hi Rodri,

Glad you have the server working correctly now!

Starting a service automatically at boot is something that is extremely dependent on the operating system's environment, so I wouldn't know for sure how to do this.
