SmartPi Energy Monitor

CircleCI

SmartPi open source.

Installation

The easiest way is to download a prebuild image. Further information under: https://www.enerserve.eu/service.html

Download Raspbian Jessie Lite from https://www.raspberrypi.org/downloads/raspbian/ and copy it on your SD card. Alternatively, you may download EmonSD, a pre-built SD card image for Raspberry Pi running as an emonPi/emonBase Download https://github.com/openenergymonitor/emonpi/wiki/emonSD-pre-built-SD-card-Download-&-Change-Log

Update packet list and update packages
sudo apt-get update
sudo apt-get upgrade
Install additional packages.
$ sudo apt-get install sqlite3 git i2c-tools avahi-daemon

For building SmartPi tools, additional packages are required.

sudo apt-get install libpam0g-dev
Enable i2c kernel module

i2c-dev is required for communicating with the SmartPi.

To check to see if the module is loaded:

sudo lsmod | grep i2c

This should return something like this:

i2c_dev                 5859  0
i2c_bcm2708             4834  0

If the module is not listed, add it to the system.

echo 'i2c-dev' | sudo tee -a /etc/modules
sudo modprobe 'i2c-dev'
Test if i2c is correctly enabled:
i2cdetect -l

The output should list your I2C channel. "i2c-1" in my case.

i2c-1   i2c             20804000.i2c                            I2C adapter
Scan I2C bus for connected devices

Channel 1 in my case

i2cdetect -y 1

In case of an SmartPi connected to an RPI3, the output should look like this:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Remove old go version
sudo apt-get remove golang
sudo apt-get autoremove
Install go

Download the archive and extract it into /usr/local, creating a Go tree in /usr/local/go. Currently version 1.17.2 is up to date. You may need to adapt the filename according to latest version.

cd /usr/local
curl -s https://storage.googleapis.com/golang/go1.17.2.linux-armv6l.tar.gz | sudo tar -xvz
echo 'PATH="/usr/local/go/bin:${PATH}"' | sudo tee -a /etc/profile

In order for the ${PATH} to be updated, you will need to logout.

Create a directory to contain your Go workspace, for example ${HOME}/go, and set the GOPATH environment variable to point to that location.

mkdir "${HOME}/go"
export GOPATH="${HOME}/go"
Building source
cd ~
git clone github.com:nDenerserve/SmartPi.git
cd ~/SmartPi
make

NOTE: Executables files are located in the bin directory

emonSD Specifics

The emonSD provides a read-only file system for most areas. You can mount the file system with write privileges by rpi-rw in order to edit files. rpi-ro reverts write privileges again. /home/pi/data is always mounted with write access. This is the location where you need to place your SmartPi database and current values file. In SmartPi's configif file /etc/smartpi you may set the following settings to move all files SmartPi is writing into.

[database]
dir="/home/pi/data/smartpi"

[device]
shared_dir="/home/pi/data/smartpi"
