SunnyWebbox with dual inverters - totals don't match

Hi,

I have a SMA PV system with dual SunnyBoys. I’m monitoring this with a SMA Webbox and have this successfully connected to the SunnyPortal where you can see larger production results. I followed the instructions to setup my system with PVOutput for dual inverters (see related post SMA Webbox Generation Totals don't match) but I’m unable to get matching production results. It appears the system may only recognize one of my inverters or some of the data isn’t getting factored in.

In the PowerKey setting I have:
WR60U06E:2000140995:Pac+WR60U06E:2000141006:Pac

My XML file has the following keys:

Any idea what the issue might be?

Thanks,
Nigel.

The key setting to add both looks correct.

How much is the difference? If is it is small then sunnyportal may be using energy instead of ‘Pac’.
