venus_kostal_pico

The plugin generates a view of the current PV power on Venus. The inverter values are used for the internal consumption calculation on Venus. It is therefore not really necessary for the system to work, but still practical.

Clone

git clone https://github.com/schenlap/venus_kostal_pico.git on your local computer (git is not installed on venus)

Configure

Kostal version 1 devices

Edit kostal.ini and add your credentials.

[KOSTAL]
ip = http://10.0.0.50 # your ip adress
username = pvserver
password = xxxx
intervall = 10 # seconds
version = 1
# 0 for AC-IN1, 1 for AC-OUT, 2 FOR AC-IN2
position = 0

Kostal version 2 devices

Version 2 devices respond on http://<IP>/measurements.xml with a xml page like

<root>
<Device Name="PIKO 2.5-1 MP plus" Type="Inverter" Platform="Net16" HmiPlatform="HMI17" NominalPower="2500" UserPowerLimit="nan" CountryPowerLimit="nan" Serial="XXXXXXXXXXXXXXXXXXXX" OEMSerial="YYYYYYYY" BusAddress="1" NetBiosName="INVZZZZZZZZZZZZ" WebPortal="PIKO Solar Portal" ManufacturerURL="kostal-solar-electric.com" IpAddress="192.168.0.1" DateTime="2021-11-06T08:10:32" MilliSeconds="055">

<Measurement Unit="W" Type="GridInjectedPower"/>
<Measurement Unit="W" Type="OwnConsumedPower"/>
<Measurement Value="100.0" Unit="%" Type="Derating"/>
</Measurements>
</Device>
</root>

Edit kostal.ini and set version 2.

[KOSTAL]
ip = http://10.0.0.50 # your ip adress
intervall = 10 # seconds
version = 2
# 0 for AC-IN1, 1 for AC-OUT, 2 FOR AC-IN2
position = 0

Kostal version 3 devices

For version 3 devices there are no login credentials necessary, leave them blank. You can test if yoh have a version 3 device if you enter http:<IP>/api/dxs.json?dxsEntries=67109120 in the browser. If you don't get an error you have a version 3 device.

[KOSTAL]
ip = http://10.0.0.50 # your ip adress
username =
password =
intervall = 10 # seconds
version = 3
# 0 for AC-IN1, 1 for AC-OUT, 2 FOR AC-IN2
position = 0

Kostal plenticore devices

For all PIKO IQ and PLENTICORE PLUS inverters see https://github.com/davwil/venus_kostal_plenticore You can check it with http:///api/v1/info/version. My plugin does not support PIKO IQ and PLENTICRE PLUS inverters!

Get root access

A step by step guide for the root access is available at https://www.victronenergy.com/live/ccgx:root_access. This is necessary for venus_kostal_pico.

Install

If setting up root access (preferable with ssh key), create a folder in data and add start script ssh int venus

mkdir /data/venus_kostal_pico
echo -e '#!/bin/bash' >> /data/rc.local
echo '(cd /data/venus_kostal_pico/ && ./start_kostal_pico)' >> /data/rc.local
chmod +x /data/rc.local
exit

and copy all files

scp venus_kostal_pico/* root@venusip:/data/venus_kostal_pico/

VELib python

VElib is necessary. Link the whole velib_python directory somewhere from venus into the directory of venus_kostal_pico or clone from https://github.com/victronenergy/velib_python.

root@venus_pi2:/data/venus_kostal_pico# ln -s /opt/victronenergy/dbus-pump/ext/velib_python ./

The structure of /data/venus_kostal_pico/ should look like this:

Test

You can test you script with /data/rc.local. You should now see your inverter on venus display. To get same debug output you can start kostal.py from the console. It should look something like this:

$ ./kostal.py
