The easiest way is to download a prebuild image. Further information under: https://www.enerserve.eu/service.html
Download Raspbian Bullseye Lite (64bit) (the big bullsyeye should also work) from https://www.raspberrypi.com/software/ and copy it on your SD card. The easiest way is to use the Raspbbery Pi Imager.
Create a user with the name smartpi and a password of your choice. We use the password smart4pi here. During installation, please use the password you have chosen and replace smart4pi with the one you have chosen.

Create user with name smartpi and password smart4pi. Use smartpi for Initial Organization Name and meteringdata for Initial Bucket Name
Login and add an addition Bucket called fastmeasurement
Create an API-Key and save it for later use. You have to adde the API-Key later in the SmartPiconfiguration

echo "tmpfs /var/tmp/smartpi tmpfs nodev,nosuid,size=20M 0 0" | sudo tee -a /etc/fstab
For secure 24/7 operation, we recommend that you also create a tmpf for the log and tmp files.
echo "tmpfs /var/log tmpfs defaults,noatime,mode=1777,size=50M 0 0" | sudo tee -a /etc/fstab
echo "tmpfs /var/tmp tmpfs defaults,noatime,mode=1777,size=30M 0 0" | sudo tee -a /etc/fstab
echo "tmpfs /tmp tmpfs defaults,noatime,mode=1777,size=20M 0 0" | sudo tee -a /etc/fstab
If you want to compile yourself, increase the value for tmp to 200M.
sudo nano /etc/logrotate.d/rsyslog
And add size 10M and change from weekly to daily. The file looks like:
/var/log/syslog
/var/log/mail.info
/var/log/mail.warn
/var/log/mail.err
/var/log/mail.log
/var/log/daemon.log
/var/log/kern.log
/var/log/auth.log
/var/log/user.log
/var/log/lpr.log
/var/log/cron.log
/var/log/debug
/var/log/messages

daily
missingok

compress

sharedscripts
postrotate

}
sudo nano /etc/logrotate.conf
The file should be looks like this:

create
#dateext
compress
include /etc/logrotate.d
sudo nano /etc/dhcpcd.enter-hook
Insert the following content:
# File /etc/dhcpcd.enter-hook
# Assign an IP alias to the eth0 interface.
if [ "$interface" = "eth0" ]; then

# Other reasons are: NOCARRIER|CARRIER|BOUND

sudo reboot
By default, the I2C bus is disabled on the raspberry Pi. It must be activated for the operation of the SmartPi. There are 2 ways to activate tccce I2C bus.
With the help of raspi-config:
sudo raspi-config
Select 3 Interface Options --> I5 I2C --> Yes
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 20480 0
i2c_bcm2835 16384 0
If the module is not listed, activate i2c via sudo raspi-config or add it in following way to the system:
echo 'i2c-dev' | sudo tee -a /etc/modules
sudo modprobe 'i2c-dev'
i2cdetect -l
The output should list your I2C channel. "i2c-1" in my case.
i2c-1 i2c 20804000.i2c I2C adapter
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
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

You can add support for the RTC by adding a device tree overlay. Run
sudo nano /boot/config.txt
to edit the pi configuration and add the RTC chip of the SmartPi
dtoverlay=i2c-rtc,pcf8523
to the end of the file.
sudo reboot
Disable the "fake hwclock" which interferes with the 'real' hwclock
sudo apt-get -y remove fake-hwclock
sudo update-rc.d -f fake-hwclock remove
sudo systemctl disable fake-hwclock
Run
sudo nano /lib/udev/hwclock-set
and comment out these three lines:
#if [ -e /run/systemd/system ] ; then
# exit 0
#fi
And also comment out:
#/sbin/hwclock --rtc=$dev --systz
#/sbin/hwclock --rtc=$dev --hctosys
Use
sudo hwclock -w
to write the time to the RTC and
sudo hwclock -r
to read the time from the RTC.
Open
sudo nano /boot/config.txt
and add:
dtoverlay=sc16is752-i2c,int_pin=24,addr=0x4D,xtal=14745600
sudo apt-get remove golang
sudo apt-get autoremove
Download the archive and extract it into /usr/local, creating a Go tree in /usr/local/go. Currently version 1.20.5 is up to date. You may need to adapt the filename according to latest version.
cd /usr/local
sudo wget https://go.dev/dl/go1.21.4.linux-arm64.tar.gz
sudo tar -xvzf go1.21.4.linux-arm64.tar.gz
sudo rm go1.21.4.linux-arm64.tar.gz
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.
cd ~
git clone github.com:nDenerserve/SmartPi.git
cd ~/SmartPi/src
make
NOTE: Executables files are located in the bin directory
Add the saved API-Key into the /etc/smartpi
influxapitoken =
Or you can add it later via webgui:
added week consumption
added modbus-server
removed support for UMTS-Sticks
