Omnik Data Logger

omnik-data-logger

This is a Python3 based PV data logger with plugin support, specifically build for the Omniksol-5k-TL2. This datalogger uses the omnikportal to fetch data pushed by the inverter. I tried using the inverter directly, but the firmware is very buggy: it either spontanious reboots, hangs or returns seemingly random data.

Installation

Install using the following command:

$ pip install omnik-data-logger

Help

usage: omnik-logger [-h] [--config FILE] [--every EVERY] [-d]

optional arguments:
  -h, --help     show this help message and exit
  --config FILE  path to configuration file
  --every EVERY  execute every n seconds
  -d, --debug    debug mode

Configuration

Example configuration

This data logger needs a configuration file. By default, it look for a config file called ~/.omnik/config.ini. You can override this path by using the --config parameter.

[omnikportal]
username = [e-mail]
password = S3cret!

[plugins]
output=pvoutput

[pvoutput]
api_key = <YOUR API KEY>
sys_id = <YOUR SYSTEM ID>
use_temperature = true

[openweathermap]
api_key = <YOUR API KEY>
endpoint = api.openweathermap.org
lon = 4.2232362
lat = 51.8819023
units = metric

PS: openweathermap is currently only used when use_temperature = true.

Run

Just run omnik-logger ... that's it ... for now.

You just need to schedule this.

Plugins

Working on a couple of plugins to customize processing of the omnik-portal data:

• pvoutput ~ write data to PVOutput
• influxdb ~ write data to a InfluxDB time series database (work in progress)
• ...
