Omnik datalogger is my solar project on Github<\/a> that enables you to do more with your Omnik Solar System logging. The manual page\/documentation has been updated and there is a now a wiki<\/a> for more information (Note: The wiki is still onder development). Thanks to Pascal Prins who’s wrote the initial code base<\/a>. His project used the omnik portal<\/strong> API, which now is no longer available. Many installed a Omniksolar PV system with a wireless datalogger to enable reporting at https:\/\/www.omnikportal.com<\/a>. Over the years this portal supplied reporting for your Omnik solar system. Now this functionality is still available at https:\/\/www.solarmanpv.com\/portal<\/a>. Many users now have a home automation system installed and want to do more with their solar data. Others want to use other reportings tools that process there solar power data. Omnik datalogger can help you achieve this. Omnikdatalogger can export Omnik inverter data to pvoutput <\/a>, an Influxdb database or publish at an MQTT broker. For Home Assistant<\/a> auto discovery is supported.<\/p>\n\n\n\n

How does it work<\/h4>\n\n\n\n

Omnik datalogger can retrieve the data from the SolarmanPV portal (the infrastructure behind Omnik portal). You can register your inverter on Solarman portal to be able to use this software using the build-in the portal clients, but you can also use omnikdatalogger without the portal . Some older Omnik inverters doe not have a possibility to get the data directly, some types do, but if not the portal seems the only place you can collect the submitted data. My inverter (installed October 2012) is of that older type, and cannot be accessed directly to get the actual data. All Omnik inverters sends an update to a fixed IP ‘176.58.117.69’ about every 5 minutes (approx. 310 seconds). This IP address seems to be part of infrastructure the Solarman. Omnikdatalogger can intercept this traffic<\/a> using the localproxy<\/strong> client. This will completely bypass the Solarman infrastructure, but needs some advances skills.<\/p>\n\n\n\n

Using tcpclient<\/h5>\n\n\n\n

If you own a newer inverter (introduced in 2013 or later) that supports local readout at port 8899, you are advised to try the tcpclient.<\/strong> This will enable polling your inverter as many times as you want, not being limitted to a 5 minute interval. A big advantage is that you will not rely on the SolarmanPV infrastructure. Further you do not need to intercept the network traffic, which requires advanced skills. If your Omnik WiFi logger is supported, you now can use the buit-in tcpclient to poll your inverter directly. Not all inverters support this method, but is worth it to try this method first before switching to interception. Thanks to Han Lubach this method could be tested. If you have any problems or questions, please let me know!<\/p>\n\n\n\n

Intercept the logger data with localproxy client<\/h5>\n\n\n\n

The inverter sends data updates to the fixed IP ‘176.58.117.69’ <\/em>that can be intercepted on your local network. The traffic is not encrypted and is decodable using the Omnik-Data-Loger project of Wouter van der Zwan<\/a>. The code to intercept I have adapted from t3kpunk at Github<\/a>. An additional proxy script<\/a> will help to support this. My logger sends updates approximately every 305 seconds. <\/p>\n\n\n\n

The new localproxy <\/strong>client together with this proxy script will help to set this up. This new client has 3 plugins (hassap, mqtt_proxy and tcp_proxy) and integrates with the proxy script through AppDaemon and Home Assistant with the hassapi <\/strong>client plugin. The mqtt_proxy<\/strong> client plugin allows to montor MQTT for the changes of the proxy script. Direct logging is supported using the tcp_proxy<\/strong> client plugin.<\/p>\n\n\n\n

Using Solarman PV API (fallback)<\/h5>\n\n\n\n

Solarman still provides the data logging for omnik portal users with the portal at SolarMAN<\/a>. Solarman announced that it will be providing this service for free till the end of the year. But the period after that is still unclear. The portal at SolarMAN<\/a> can still be accessed using the same login credentials that ware used at the Omnik portal. There is 1 API’s Omnik datalogger supports to fetch the data collected from your inverter.<\/p>\n\n\n\n
