omnikdataloggerproxy 1.0.0

Omnik Data Logger Proxy

OMNIKDATALOGGERPROXY

Use these files to intercept your inverters data messages. See the comments in the example shell script en config.ini about how to use them. Good luck with them

Install using pip3

pip3 install omnikdataloggerproxy

Prearing your Synology to run run omnikdatalogger the proxy script (manual install)

• Make sure you have shell access (ssh or telnet).
• Install pip: curl -k https://bootstrap.pypa.io/get-pip.py | python3 See: (https://stackoverflow.com/questions/47649902/installing-pip-on-a-dsm-synology)
• Install the paho mqtt client: /volume1/@appstore/py3k/usr/local/bin/pip3 install paho-mqtt. The path may be diferent. I used a Synology DS218 play

On upgrades it might be neccesare to reïnstall pip and paho-mqtt. Make sure you chack on this after an update for your Synology.

Now take the following steps:

• Place the omnikloggerproxy.py script, the bash script (omnikproxy_example_startup.sh) and config.ini_example.txt to a folder that will not be affected by upgrades. E.g. /volume1/someshare/yourscriptfolder.
• Rename config.ini_example.txt to config.ini and configure settings.
• check the commandline settings in the shell script.
• Try to execute the script to test if it is working. (You can use task plannel later to start the script at boot automatically as activated task)
• The lines to configure iptables should run as root. The omnikproxylogger script works at userlevel too.
• On your internet router/gateway, set up a static route for 176.58.117.69/32 to your synology.
• Configure MQTT to forward the data to be able to use the localproxy plugin with hassapi or mqtt_proxy.

You can forward the logger trafic to the omnik servers, but if you rerouted yhe traffic for 176.58.117.69 you need to forward to a linux server elswere in the internet.

Prearing your Synology to run run omnikdatalogger the proxy script

You can use the following systemd config to run the script as a service (The example shows a forwarding only setup)
