Hello, I have installed the dongle a few days ago. When I compare the electricity production results between the SolarEdge app and the homey energy tab, the differences are big (Solaredge 16,4 kwh vs Dongle 27.6 kwh. I use mono phaze inverter. See pictures.  
Anybody an idea what is wrong.  
Thanks for your help.

It looks like your sunpanels are counted twice in the Energy Tab, one as invertor and one as Modbus. You can exclude one in the advanced settings of the device.  
The Homey dongle measures your P1 Energiemeter, not your sunpanels..

Thanks for your reply.  
Could be, but I am not able to reconstruct the figure of the Dongle with your suggestion.

No it is. In the Energy tab there is a device Modbus and a device Invertor as shown in your figure.  
Probably the devices are installed during the current day shown, so they don’t report the same period, and thus is the PV production not twice the figure of your invertor.

OK, I have elimated the modbus and will check tomorrow what figures are produced

It takes a while before the Modbus device will disappear from the Energy Tab, when you exclude it in the advanced settings.
