Hi Jim!  
my fronius was installed some weeks ago and since last week i also can export to grid.  
i configured the binding with text files and i don’t get any errors, but the values i get from the binding differ from the values i see in the fronius app…

Binding data:

```auto
fronius:powerinverter:mybridge:myinverter:inverterdatachanneltotal = 0.3852054927777778 MWh
fronius:meter:mybridge:mymeter:energyrealsumconsumed = 1015811 Wh
fronius:meter:mybridge:mymeter:energyrealsumproduced = 93519 Wh

```

Here’s a screenshot from the app:

according to your post `inverterdatachanneltotal + fronius:meter:mybridge:mymeter:energyrealsumconsumed - fronius:meter:mybridge:mymeter:energyrealsumproduced ` should equal `household consuption`, right?

but `385.21 kWh + 101.58 kWh - 93.52 kWh = 393,27 kWh` whereas the app tells me consumption was 1319.99 kWh ?

What am i missing?

and which values should i use to replicate this info from the app?

the last one (“to grid”) is the value from `fronius:meter:mybridge:mymeter:powerrealsum`

first value shoud be `fronius:powerinverter:mybridge:myinverter:powerflowchannelppv` (same as `fronius:meter:mybridge:mymeter:powerrealsum` ?)  
last one should be `fronius:powerinverter:mybridge:myinverter:powerflowchannelpgrid`  
but is there also a channel for the 2nd value (total consumption)? or is this just the difference between the 2 (given) values?

hope you still use this binding and can provide some insight!

best regards,  
Peter
