Raspberry Pi Setup
Raspbian Linux Setup
- Download Raspbian 'Wheezy' SD card image This guide was made using 18th September 2012 release.
- Copy SD card image on SD card using Linux tool "dd" for any other OS see Raspberry Pi tutorial
- Insert SD card
$ df -h
to view mounted partition, make note of SD card device name, for me this was 'sdb'
- Unmount SD card
$ umount /dev/sdb1
you will need to change sdb to match your SD card drive. If the card has more than one partition un mount that also $ umount /dev/sdb2
- Write the .img to the card
$ sudo dd bs=4M if=~/Downloads/2012-09-18-wheezy-raspbian.img of=/dev/sdb
again you will need to replace sdb with your SD card device name and modify the location and name of the image as need.
- Put SD card into Pi and connect network and power
- Find the IP address of the Pi and SSH to it
$ SSH [email protected]
, default password is 'raspberry'
- Once successfully logged in run Raspbian setup
$ sudo raspi-config
- Select Expand root partition to fill SD card finish and reboot
- One rebooted restart SSH connection and run
$ sudo raspi-config
again
- Check for updates
- Change password for user Pi to something of your choice, make it secure it will be storing your home energy data!
- If you plan to run the Pi as a headless dataloggin emoncms server as we do then select memory-split and choose the first setting a 240/16 split, the gives the CPU more memory at the expense of graphics which we're not using
- We also recommend selecting boot behaviour and disabling booting straight into a desktop since this increases boot time and wastes system resources. If required a desktop can be loaded with
$ startx
.
- Set locale and timezone as required
- Finish and reboot, remember to use your new password when SSH'ing back in!
- (optional) set a host name for the Pi to enable host name to be used instead of IP address when connection to the Pi
- Enter the host name your desire eg.emoncms in the file
$ sudo nano /etc/hostname/
[Ctrl+X] then [Y] then [Enter] to save and exit
- and in the file
$ sudo nano /etc/hosts/
{Ctrl+X] then [Y] then [Enter] to save and exit
- Reboot the Pi and you should be able to SSH back in with
$ ssh [email protected]
if 'emoncms' was your chosen host name.
- I had trouble getting host name to work, does this work for you?
Emoncms Setup
- Install emoncms following this guide up to the end of section 7
- Instead of emoncms3 on the OpenEnergyMonitor GitHub use
$ git clone git://github.com/emoncms/emoncms.git
as the GtiHub emoncms repo. This is a new 'modular' version of emoncms. Alternatively you could download the zip file from github an extract into /var/www
- Navigate to the emoncms modules folder
$ cd emoncms/Modules
- Download the Raspberry Pi emoncms module into the Modules folder
$ git clone https://github.com/emoncms/raspberrypi.git
- Now carry on following the emoncms install guide section 8-10.
- Note: since we're using the new modular version of emoncms the first bit of step 9 should be
$ cd /var/www/emoncms/
- When you've finished you should be able to browse to Http://Pi IP address or Host/emoncms, create and account and test posting data with the 'try me' button in the API section.
