Basically you look at it from the fronius “Box” perspective. Anything that comes INTO the box is positive and anything that goes OUT from the box is negative.

Things that flow into the box:

  • Power you draw from the grid
  • Power that comes from the solar panel

Things that flow OUT from the box:

  • Power that goes to the load in the house
  • Power that feeds back to the grid (power from grid is positive but when it flows out to the grid it’s the negative of power “from” grid)

The total sum of power in + out = 0

So be able to “isolate” an item to household consumption, I will have to calculate in/out in a script?

Hi Simon.
Do you get any udates from these three channels?
I have a 10kW Symo Gen24 inverter, and I get no updates about day, total and year? Other channels are working fine.

I’m also struggeling with calculation of the current load.. The Channels gives back wrong values. See screenshots an explanation here:

@Kim_Andersen - wow, two years and I finally get back to programming. Talk about a sabbatical. I cannot confirm I am getting data from those. For starters I’m going to need to update my whole setup to OH4.5 (or whatever the latest it) which will no doubt cause all sorts of cascading errors with my code. Once I’ve gone through that pain I’ll come back and see if there’s more data I can grab out of the Fronius.

You can get the information via Main UI → about

Yes, upgraded from OH4.1.1 to OH4.3.5 with no issues at all!! Matter of fact, it now gives me health messages about my code (much to my embarrassment - but hey I’ll take the help thanks!).
