If you have bought a SmartPi with preinstalled software, you can skip this chapter.
You have 2 different possibilities to install the SmartPi software on your computer:
- Installation of a ready-made image
- Installation via the software repository
Own installation vs ready image
If you want to install the software yourself, you will have to install and configure some programs yourself, as they are not included in the repositories.
Installing a ready image
The simplest variant is to install a ready-made image.
At http://files.enerserve.eu/smartpi/smartpi-buster.7z you can load a ready configured image.
In contrast to the original Raspbian, many log files are moved to the ramdisk and some partitions are write-protected. Download the image and unpack the file. You need a program which can unpack 7zipfiles (Windows:http://www.7zip.org).
Installation under Windows:
- Download the program Win32DiskImager from https://sourceforge.net/projects/win32diskimager/
- Insert the SDcard into the SDcard reader of your PC
- Note the drive letter of the SDcard. You can see the drive letter in the left column of Windows Explorer, e.g. G:
- Run the program you downloaded earlier.
- Select the unzipped file (*.img) in the "Image File" field.
- Select the drive letter of the SDcard in the "Device" selection field and click on "Write".
- Wait until the writing is finished
Installation under Linux:
Use the command dd.
dd bs=4M if=path_of_your_image.img of=/dev/sdX conv=fsync

Mac OS X:

Installation from the repository
To make the installation easier for you, we offer an installation script at http://files.enerserve.eu/smartpi/installsmartpi.sh ein Installationsskript an.
Proceed as follows:
Log in via ssh and execute the following commands to add the SmartPi repository:
sudo apt install apt-transport-https
sudo wget https://repro.enerserve.eu/packages/Release.key && apt-key add Release.key && rm Release.key echo "deb https://repro.enerserve.eu/packages stretch main" /etc/apt/sources.list.d/enerserve.list apt-get update
Download the script, make it executable and run it.
chmod a+x installsmartpi.sh
The script will guide you through the installation.
Use the following commands to add the SmartPiRepository:
apt install apt-transport-https
wget https://repro.enerserve.eu/packages/Release.key && apt-key add Release.key && rm Release.key echo "deb https://repro.enerserve.eu/packages stretch main" /etc/apt/sources.list.d/enerserve.list apt-get update
Run the following command:
curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
sudo apt update
sudo apt install influxdb telegraf
Then edit the configuration file of InfluxDB:
sudo nano /etc/influxdb/influxdb.conf
In the [http] section, check that the following lines are commented out and have the appropriate values:
enabled = true
bind-address = „:8086“
auth-enabled = true
Activate and start the database:
sudo systemctl enable influxdb
sudo systemctl start influxdb
influx -execute "CREATE USER smartpi WITH PASSWORD 'smart4pi' WITH ALL PRIVILEGES"
influx -username admin -password smart4pi -execute "CREATE DATABASE MeteringData"
influx -username admin -password smart4pi -execute "CREATE CONTINUOUS QUERY minmax_1h ON MeteringData BEGIN SELECT max(CosPhi1) AS MAX_CosPhi1,max(CosPhi2) AS MAX_CosPhi2,max(CosPhi3) AS MAX_CosPhi3,max(F1) AS MAX_F1,max(F2) AS MAX_F2,max(F3) AS MAX_F3,max(U1) AS MAX_U1,max(U2) AS MAX_U2,max(U3) AS MAX_U3,max(I1) AS MAX_I1,max(I2) AS MAX_I2,max(I3) AS MAX_I3,max(I4) AS MAX_I4,max(P1) AS MAX_P1,max(P2) AS MAX_P2,max(P3) AS MAX_P3,max(P3) AS MAX_P3,min(CosPhi1) AS MIN_CosPhi1,min(CosPhi2) AS MIN_CosPhi2,min(CosPhi3) AS MIN_CosPhi3,min(F1) AS MIN_F1,min(F2) AS MIN_F2,min(F3) AS MIN_F3,min(U1) AS MIN_U1,min(U2) AS MIN_U2,min(U3) AS MIN_U3,min(I1) AS MIN_I1,min(I2) AS MIN_I2,min(I3) AS MIN_I3,min(I4) AS MIN_I4,min(P1) AS MIN_P1,min(P2) AS MIN_P2,min(P3) AS MIN_P3,min(P3) AS MIN_P3 INTO hour FROM data GROUP BY time(1h),serial,type END"
influx -username admin -password smart4pi -execute "CREATE CONTINUOUS QUERY yield_balanced_day ON MeteringData RESAMPLE EVERY 30m BEGIN SELECT INTEGRAL(P1,1m)/60 AS E1,INTEGRAL(P2,1m)/60 AS E2,INTEGRAL(P3,1m)/60 AS E3 INTO day FROM data GROUP BY time(24h),serial,type END"
There is currently no repository for Grafana. Therefore, check https://grafana.com/grafana/download?platform=arm to see if there is a newer version than the one used here.
sudo dpkg -i grafana-rpi_6.1.6_armhf.deb
sudo systemctl enable grafana-server
sudo systemctl start grafana-server
sudo apt install smartpi
sudo apt install smartpi
To update the software in the future you only need to execute the following command:
sudo apt install smartpi
By default, the SmartPi is delivered with DHCP. This means that it is assigned an IPaddress by your router. To find out the IPaddress of your SmartPi, you can either look in the list of registered on your router or search the IPaddress with a network scanner Angry IP (http://www.angryip.org) or Netscan.
The hostname of the correct IP must be "smartpi" or "raspberry". You can now access the website with http://<IPaddress>:1080.
A sshlogin is also possible:
Password: smart4pi or raspberry
In the case of an Internet share (port share), we strongly recommend that you change the user's password for security reasons (command: passwd). The default password is known and allows hackers very easy access to your SmartPi and thus to your home network.
You can reach the web interface at http://<IPaddress>:1080
The web page currently displays the current values of power, current, voltage, cos phi and frequency. A bar display shows the energy of the last 8 days.
A right click on Chart opens the display of the daily history of all measured values. A click on the button of the corresponding value adds the value to the daily history. Another click removes it again.
The button "Day back" can be used to go back one day. The button "Day forward" jumps one day forward. The "Add day back" and "Remove day back" buttons can be used to extend or shorten the day view to several days.
The table view can be selected via the drop-down menu at the top left. Here a view or an export of the table is possible. Via the date fields an exact period can be selected. Please note that it may take some time until the view is loaded.
The configuration page can also be loaded via the drop-down menu. For access you need user name and password. These cannot be changed at this time:
In the "default settings" you can assign a serial number, a name and coordinates to the smartpi. When using the API (at http://blog.enerserve.eu) this information is already evaluated.
The tab "measurement" contains all settings for the measurement. Here you can select the appropriate frequency for your country (50Hz or 60Hz). Furthermore you can set at which phase the measurement should be done and which sensor is connected. Here you can also set whether the voltage is to be measured or assumed. The corresponding voltage can then be set.
