Omnik Statistics

===== Omnikstats will search for your (WIFI connected) Omnik solar inverter and then download its statistics. Statistics can be logged to a CSV data file and/or uploaded to PVoutput.org

With a 5 minute interval cronjob, this program can upload statistics to PVoutput.org

You only have to edit omnik.conf with your APIkey and System ID, to be provided by PVoutput.org

Installation and Setup

• You may have to update first: sudo apt-get update
• The curl development must be installed: sudo apt-get install libcurl4-openssl-dev
• Clone the source with sudo git clone https://github.com/arjen/omnikstats.git
• Edit omnik.conf with your API key and SystemID
• do a make clean
• do a make all
• run: ./omnikstats -? for the usage.

cronjob

The following cronjob command starts omnikstats every 5 minutes between 6 AM and 11 PM (no use to get statistics during night time)

*/5 6-22 * * * /<path to omnikstats>/omnikstats

UPDATE

On my raspberry, the cronjob did not start in the correct directory. Further, pvoutput only registers every 10 minutes so edit cronjob with: (enter sudo crontab -e)

*/10 6-22 * * * cd <path to omnikstats> && /<path to omnikstats>/omnikstats

REMARKS

• If no key and/or systemID is provided the program will still run (with an error from PVoutput)
• This program might not work for all Omnik inverters. Contact me for possible solutions.
• If you have more than 1 string in your solar system, it will get the statistics and -if desired- will log this to CSV. However, only the first string will be uploaded to PVoutput.org (for now)
