First of all - Thanks for your work!

I got a PH1800 10048 hybrid inverter.
First it was connected to the cloud via stock dongle. Monitoring via SmartESS mobile app.
The app is pretty poor, but what was really weird, is that there were TWO devices instead of only ONE (since I got only one inverter).
First I thought is was a duplicate and deleted one of them. But after some time it has re-appeared.
Then I realized that one of those devices (second one) doesn't show any solar activity info. This is probably because I have PV connected only to 1st tracker, 2nd MPPT tracker is not in use.
And finally the amount of energy used from the Grid (according to 1st device) was way smaller then on the meter of my supplier company. But it was nearly equal to the sum of 1st+2nd devices.
So, looks like my inverter it basically 2 inverters combined in one.
This is pretty annoying, cuz I cannot get all info in one peace.

Yesterday I finally received modbus to wifi dongle. After some configurations I've managed to add my PH1800 to HA.
It found one device (which I thought was grate), but it seems like it is 1st device only.
So I don't get real info from inverter, only half.

Describe the solution you'd like

It would be nice either to have a possibility to add second device, and handle data merging in HA.

Describe alternatives you've considered

Or to combine the data in this integration, which I suppose is much harder to do.

Additional context

This is Smart ESS App
