Hi,
these are the steps to install vzlogger on an Orange Pi Zero by using a volkszaehler TTL device as interface to get the measures of the electricity meter. Connect the Output to the Pin 10/GPIO199/UART1_RX
First of all install Armbian .
Enable UART1. Open /boot/armbianEnv.txt and add the device tree overlay.
overlay_prefix=sun8i-h3 overlays=uart1
Reboot the PC. If the volkszaehler TTL interface is already connected you can check if data are received.
Install python serial and start python
root@debdev ~ # apt install python3-serial root@debdev ~ # python3
Enter the following code
import serial
# Serielle Schnittstelle konfigurieren
ser = serial.Serial('/dev/ttyS1', 9600, timeout=1)
while True:
data = ser.read(16) # Read 16 Bytes
if data:
print(data.hex()) # print Bytes as Hex
This should be shown something like this:
77070100100700ff0101621b52005900 000000000000060177070100240700ff 0101621b520059000000000000000601 77070100380700ff0101621b52005900 0000000000000001770701004c0700ff 0101621b520059000000000000000001 77070100200700ff0101622352ff6900 000000000009490177070100340700ff 0101622352ff69000000000000094a01 77070100480700ff0101622352ff6900 0000000000094701770701001f0700ff 0101622152fe69000000000000000401
Download, build and install vzlogger
root@debdev ~ #apt-get install extrace git-core cmake libtool dh-autoreconf uuid-dev libmicrohttpd-dev \
build-essential pkg-config libgnutls28-dev libssl-dev libmosquitto-dev libgcrypt20-dev libcurl3-dev \
libunistring-dev libssl-dev libsasl2-dev libcurl4-openssl-dev uuid-dev libtool libltdl-dev
root@debdev ~ # mkdir ~/software
root@debdev ~ # cd ~/software
root@debdev ~ # export CMAKE_INSTALL_PREFIX=/usr/local
root@debdev ~ # wget https://raw.github.com/volkszaehler/vzlogger/master/install.sh
root@debdev ~ # bash install.sh vzlogger libjson libsml mqtt
Create a user vzlogger and add it to the dialout group to get access to the serial device(s)
root@debdev ~ # useradd -r -s /sbin/nologin vzlogger root@debdev ~ # usermod -a -G vzlogger vzlogger root@debdev ~ # usermod -a -G dialout vzlogger
Edit /etc/systemd/system/vzlogger.service and adjust as seen below
vi /etc/systemd/system/vzlogger.service [Unit] Description=vzlogger After=syslog.target network.target [Service] User=vzlogger Group=vzlogger ExecStart=/usr/local/bin/vzlogger -c /etc/vzlogger.conf ExecReload= StandardOutput=null ExecStartPre=-/usr/bin/mkdir -p /var/log/vzlogger ExecStartPre=-/usr/bin/chown vzlogger:vzlogger/var/log/vzlogger [Install] WantedBy=multi-user.target
Add als the following lines to /etc/rc.local (before exit 0 :-))
/usr/bin/mkdir -p /var/log/vzlogger /usr/bin/chown volkszaehler:volkszaehler /var/log/vzlogger
then you have to define your Smartmeter/electricity meter config. For me a EFR SGM-C8.
Create a file /etc/vzlogger.conf
