Did you manage to get the omnik data into Toon?[/quote]
(next level: find a way to get the data from my Omnik inverter into Zon op Toon)
Didn't look into this for a long time...
In short: no.
Buying, installing and monitoring a seperate metering device - while all the data is already monitored and available in the Omnik inverter itself, the Omnik portal, my rpi, PVoutput and Domoticz - seems rather silly.
I'm still hoping for someone to find a way to "inject" the available data into Zon op Toon...
